☆、Four personalities ([-])

At an altitude of [-] meters, the plane encountered a turbulence and was violently bumped for a while.

Cheng Yan was shaken awake.He took off the blindfold, looked at his watch, and found that he had only slept for less than 10 minutes, and there were at least three and a half hours before the plane landed.

Cheng Yan's check-in time was not early, and the seat was assigned to the second-to-last row near the window.The tail of the plane was shaking extremely violently in the air current. Sitting next to him was a family of three, a young couple with a child who looked like two or three years old.At this moment, the fuselage has not stabilized, and the sweet voice of the stewardess sounded on the radio, asking all passengers to sit in their seats and fasten their seat belts.She said it first in English and then in Mandarin, in a gentle voice, but it didn't do much for some passengers.

The child has been crying since Cheng Yan woke up. He has been wailing for 5 minutes without stopping. His parents are more and more at a loss. The mother holds the child in her arms and keeps patting and coaxing him. Trying to divert the child's attention with the newspaper folded into a small animal in his hand, looking up from time to time to see the reactions of other passengers, and whispering "I'm sorry" in both Chinese and English, appearing anxious and embarrassed.

Fortunately, the nearby passengers also showed full understanding. The old American lady sitting in the front row thoughtfully moved the seat forward to leave more space for the couple and the scared child.The passing stewardess also stopped, leaned over to comfort the child, and handed him a cup of hot water.It's a pity that these measures had little effect. The child was probably on a plane for the first time. He was so frightened that he was hoarse from crying and was still sobbing and howling.

Realizing that Cheng Yan was looking at them, the father forced a smile and apologized again and again: "I'm really sorry for disturbing you."

Cheng Yan shook his head: "It's nothing, I was awake."

Of course, he could have continued to sleep for a while.

But he wouldn't say these words, nor would he show them on his face.In front of outsiders, Cheng Yan always had a talkative demeanor, his manners were gentle and gentle, making him amiable.For example, now, no one can see that he actually hates being woken up while sleeping, and he never likes dealing with children.

The man probably also thinks that Cheng Yan is a good person, so he wiped the sweat off his face helplessly, and then said: "My son usually doesn't make trouble at home, even if he starts to cry, he will be quiet after a few words with his mother. I know today... oh."

Cheng Yan listened silently, nodded understandingly, took off his earphones, moved closer to the child, hung them lightly on the side of the child's head, and paid special attention to make sure they didn't press the little guy's ears.

The headphone cable was still plugged into his computer, and the music didn't stop.

In less than 2 minutes, the child slowly stopped crying, opened his mouth, and yawned. His expression of being bitter and vengeful just now turned into a drowsy expression, with his head He arched into his mother's arms, and his hands and feet stopped moving, as if he had suddenly entered silent mode.

The couple stared blankly at their son for a while, and then at Cheng Yan, their surprise was beyond words, as if he had performed a magic trick in public.

Cheng Yan could only briefly explain: "A sleep aid."

Sometimes scientific methods are more direct and effective than human language communication, especially when the person trying to communicate is a child whose brain function is not yet fully developed.

The child's father wanted to thank him. Cheng Yan made a quiet gesture and pointed to his precious son who had finally fallen asleep. Under the grateful eyes of the couple, he put on the blindfold and leaned back in his seat.

There was no white noise in his ears, and for the next three hours or so, Cheng Yan didn't fall asleep for another minute.

After finally surviving until the plane landed, when the entire plane was slowly emptied, Cheng Yan stood up, first helped the couple next to him unload their luggage, and then took his own.

Maybe it was because of the crying and fussing just now that consumed a lot of energy, the child was still sleeping soundly in his father's arms, with a stream of saliva dripping from the corner of his mouth.

The child's mother carefully took off the earphones, returned them to Cheng Yan, and said thank you several times.

The four of them walked out of the plane together with the flow of people. Along the way, the couple enthusiastically chatted with Cheng Yan, from what he did to the United States, how long he would stay this time, and asked him what job he had in China and where he lived. I plan to recognize my son as a godfather.

Cheng Yan responded as best he could, but he wasn't impatient, but most of the questions were vague, and when he saw the luggage claim sign, he immediately expressed regret that he didn't have checked luggage, so he went ahead, and walked away quickly after speaking. Faster than when I was catching a plane.

He dragged the suitcase into the nearest restroom, took off his glasses and turned on the faucet, and couldn't wait to wash his face with cold water.

The water trickled down from the wet temples and knocked on the tiles of the sink. Cheng Yan felt a muscle in his head jumping up and down. The pain was so overwhelming that it almost made his stomach shiver. Spit in the pool.

There was still buzzing in his ears, and the sunken eardrum hadn't recovered automatically, so he didn't need to listen to white noise anymore, his eyes and mind were filled with noise spots.

Cheng Yan paused for a few seconds before raising his head.

The man in the mirror was pale, as if hungover.

Cheng Yan secretly rejoiced, fortunately he came back a day early this time, otherwise he would report to the school with such virtue, fearing that the department leaders would suspect that the newly hired researcher had a serious illness or bad conduct.At any rate, he will be regarded as a model teacher in the future, and he still can't afford to lose this person.

He wiped the water off his cheeks with his backhand, unzipped the outermost zipper of the suitcase, touched a small medicine bottle with his fingertips, hesitated for a moment, ignored it, and took out a wipe from another inner pocket on the side. Lens paper, wipe off the water vapor on the rimless glasses, and put them back on the bridge of the nose.

The pocket of the windbreaker was bulging. He remembered that it was the earphones he borrowed on the plane just now. He was about to take it out and put it away again when he realized that the tentacles were sticky.

In all likelihood it was the child's saliva.

Cheng Yan frowned, took out the earphones, threw them into the trash can beside him, washed his hands again, and walked out of the bathroom.

At this time, the cell phone in the other pocket rang.

Cheng Yan's mobile phone number in China has been useless for five years and has been canceled long ago. At this time, he has not yet reissued a new card, so the phone probably automatically connected to the airport wireless.

He hastily glanced at an unread email from Xu Mowen, with only a single line of words and two questions.

"Are you here? Are you airsick again?"

Cheng Yan walked towards the exit without raising his head, and typed a reply with one hand: "Yes. No. Thank you teacher for your concern."

He has lived for more than 20 years in his life, from kindergarten all the way to Ph.D., and met eighty if not a hundred teachers, but Xu Mowen is the only one who makes him call him a teacher instead of a certain teacher.

Cheng Yan's parents mixed from the academic world to the business world. When they were busy with work, they traveled all over the world. They didn't spend much time with their son since he was very young.When Cheng Yan was 12 years old, they even settled in the United States directly. Naturally, they planned to take Cheng Yan away, but Cheng Yan only stayed in the United States for less than a year, and then ran back to the country alone. In the next five years of middle school and four years of university, they all lived under Xu Mowen's care.

Xu Mowen is an undergraduate classmate of Cheng Yan's father, who has been firmly rooted in the academic world over the years, and is now regarded as the pinnacle of psychiatry in China.He was originally a professor at Jiangcheng University and concurrently the director of the Mental Health Center. It was a coincidence that he went to Germany as a visiting scholar at the very moment when Dr. Cheng Yan graduated and returned to China, and he would not come back until a year later.

Although he is not in the country, and there is a half-day time difference between China and the United States, Xu Mowen obviously still keeps the time when Cheng Yan's plane landed in his heart, and sent an email as soon as possible to inquire about the situation.

Within a minute, Cheng Yan received a new reply.

"Remember to take medicine for headaches. I have transferred your things to Mu Mu. When you get home, take a good rest and contact her tomorrow morning."

Cheng Yan replied "Yes", put down the phone, and a little smile appeared on the corner of his mouth.

No matter how hard he said that his head didn't hurt, he couldn't hide it from the teacher.After all, from childhood to adulthood, there was never a time when he was able to fly without airsickness. It might be better when he grows up, at least he didn't vomit like he did when he was a child, scaring Xu Mowen so much that he wanted to send him to the hospital as soon as he got off the plane.

After queuing for half an hour, Cheng Yan finally got into a taxi.

The driver was a middle-aged man in his 40s. He helped Cheng Yan move his luggage to the trunk, and he got into the mood as soon as he closed the car door. The students must be very smart."

It's been a long time since I've heard the local dialect of Jiangcheng. It took Cheng Yan a while to react and deny it: "I'm not a student."

Driver: "That's right, it doesn't look like it. How can a young boy who is still in college have such an air. Let me tell you, college students nowadays, even boys, like to dress fancy..."

As he spoke, he talked endlessly, from the latest central bank interest rate cut policy to the newly built subway line near the airport, and he would shake his head with few hairs left when he talked about the rise.

Cheng Yan leaned on the back seat, half-closed his eyes, and responded a few times, continuing the conversation.

The summer night in Jiangcheng was not too hot. The driver did not turn on the air conditioner to save fuel. The wind came in through the half-opened car window, blowing on his wet hair and face. It was quite cool and comfortable.The driver's mandarin with a thick accent played a similar effect to white noise, the awkward tendon in Cheng Yan's head finally settled down, the pain gradually subsided, and drowsiness followed.

It was dark in front of my eyes, and every once in a while, a little white light jumped over quickly.

"Thirteen."

Cheng Yan counted silently in his heart. In 1 minute, thirteen cars passed by on the opposite side.The road is still the same, and the city is more lively than it was five years ago.

The driver thought he was asleep, and gradually stopped talking.

After a while, the person in the back seat suddenly said, "No need to go to the overpass."

The driver was startled, a little embarrassed, and muttered, "Oh, I almost saw the wrong way in the middle of the night. Fortunately, you know each other, otherwise I almost took a detour."

Cheng Yan didn't speak, then closed his eyes.

He asked the taxi to stop at the east gate of Jiangcheng University, got off the bus and stood there for a while, instead of going to the opposite community, he dragged his suitcase and walked 50 meters, and entered a hotel on the street.

Cheng Yan took a shower, took a set of long-sleeved trousers that he didn't usually wear from the suitcase, changed into them, and lay down on the bed.

He lost his earphones, and he was unwilling to play the music publicly, so he had to lie down for three hours before barely falling asleep.

Then the phone rang again.

Cheng Yan grabbed the phone from the bedside table and took a look, this time it was an overseas call.

"Well, Mom. It's yesterday's flight, and I'm in Jiangcheng now. I've contacted the teacher. Okay, I know, go get busy if you have something to do." He finished speaking calmly, hung up the phone and sent another email , then pressed the off button, and lay back on the bed straight.

This time Cheng Yan fell into a deep sleep and didn't even have a dream.

Until a loud knock on the door woke him up.

The author has something to say: It’s the first pitfall of Zheng’er’s Eight Classics... I hope some new friends are willing to ask me to play XDDD

Another: The author is not a psychiatrist. If you find a bug, please feel free to point it out.

☆、Four personalities ([-])

Cheng Yan put on his glasses, got up from the bed, adjusted the hem of his clothes, and opened the door unhurriedly.

Standing at the door was a pretty girl, not tall, wearing a pink and blue dress. As soon as the door opened, she stepped on her high heels and rushed into the room aggressively.

"Cheng Tuhao, you'll be staying in a hotel as soon as you come back. I thought you'd dated a girl." She gave Cheng Yan a sideways look, and sat down on the sofa beside the bed.

Cheng Yan put his hands in his trouser pockets, ready to go to the bathroom to wash up, and said leisurely, "You have the key to my house."

A cry came from behind: "What, there are keys to your house in the pile of junk that the boss gave me?"

Cheng Yan squeezed the toothpaste calmly: "The house is here, and I can't take it away. What am I going to do with the key?"

"Let me do the math. After you left, the housing price has increased by at least three times in the past five years, and now your small apartment is worth 300 million." The people outside followed, leaning on the door frame, gently Lightly kicked Cheng Yan's calf, "Be good, call me Senior Sister."

With water in his mouth, Cheng Yan didn't intend to talk to her.

Mu Mu is a doctoral student under Xu Mowen's supervision. He is one level higher than Cheng Yan. They have known each other since they first entered university.After graduating from her Ph.D., she didn't go to other places. She stayed in the department as a postdoctoral fellow, and by the way, worked as a small boss for Xu Mowen. When Xu Mowen left, he entrusted Cheng Yan to her.

Seeing that Cheng Yan refused to obey obediently, Mu Mu smiled sweetly and threatened: "Don't call me senior sister, the house will be mine. Tsk tsk, school district house, how much can I earn from renting it out..."

Cheng Yan said "Oh", put down his glass, turned outside, and picked up his phone.

Mu Mu was annoyed: "Brat, it's been five years since I've seen you, so you're even more arrogant. How dare you ignore your senior sister!"

Cheng Yan: "I'll send an email."

Mu Mu leaned over: "Who is it for, female ticket?"

Cheng Yan: "... Teacher."

Mu Mu was startled: "It's really shameless to dare to sue the imperial court!"

Cheng Yan put the phone back in his pocket: "I can send it later."

Mu Mu immediately surrendered: "Okay, back to school, everything is in my office."

She has always been afraid of Xu Mowen, or not afraid, but awe of admiration. In Cheng Yan's eyes, Xu Mowen is both a teacher and an elder, and in Mu Mu's eyes, he is both a teacher and a boss. As soon as Cheng Yan put out Xu Mowen, Mu Mu lost all arrogance and retreated.In her words, Cheng Yan is simply a shameless villain who relies on his teacher's favor to make trouble. younger brother.

Cheng Yan didn't really want to threaten Mu Mu, he was old anyway, how could he do such tricks like kindergarten kids suing the head teacher.Seeing that Mu Mu was automatically discouraged, he followed suit, put his phone back, and planned to reply to Xu Mowen's email after he had been to school.

"I was planning to go to school to find you." Mu Mu stayed in the room, so he had to go back to the bathroom to change his shirt.

Mu Mu snorted: "Well, the young master has returned from his studies, and the young one is already very anxious if he doesn't go to the airport to pick him up. How dare he wait for you to go to the school to find me? I promised the boss that I will pick you up at school. You didn't tell me that you lived here, and I couldn't open the door when I went to your house early in the morning, so I thought you had been kidnapped, so I was so frightened that I called the police."

"I'm rich and colorless, and I'm sober, who will kidnap me." Cheng Yan glanced at Mu Mu as he walked by, and added, "It's not like you."

"Have a conscience, I know that your senior sister is talented... Well, you want to say that I have no brains!" Mu Mu reacted, and was so angry that he wanted to kick someone, but Cheng Yan hid away without looking.

Cheng Yan buttoned it up and pulled the suitcase in his hand: "Let's go to school."

Mu Mu looked around: "Don't tell me you took a boarding case when you returned home?"

Cheng Yan: "The books have all been sent back, and they are still on the way."

Mu Mu couldn't believe it: "What about the clothes? What about other sundries? You have been in the United States for five years, and this is all you need?"

When others go back to China, they are full of big bags and small bags, and they can't wait for one person to carry two 28-inch large boxes.

Cheng Yan frowned: "Things outside the body, I will buy them when I come back."

Mu Mu sighed while shaking his head: "Tsk, you are really cold-blooded and ruthless. I read you right."

Cheng Yan: "I'm still going after my life. Miss, if you don't hurry up, I'll be late on the first day, and I'll ask you for the deducted bonus."

He only had a small boarding case in his hand, but Mu Mu still insisted on snatching it into his hand, euphemistically saying that since he said he would pick up someone, he must do it right, and he must not break his promise to the boss, and taking care of the younger brother is a matter of course, she is not like Some people don't know how to respect the old and love the young.

Cheng Yan had no intention of arguing with her over such a trivial matter, so he let her go.

The school is about to start these few days, and the freshmen have come to report one after another. Most of the passers-by are dragging their luggage. Seeing the two of them entering the school together, the petite girl is struggling to drag her luggage, while the big man beside him is empty-handed. They all cast contemptuous glances at Cheng Yan.

Even the security guard directing traffic at the gate couldn't stand it any longer, and said righteously, "Student, help your girlfriend."

Cheng Yan was speechless, intending to reach out and drag the luggage back.

"It's okay, brother, this is my younger brother." Mu Mu smiled at the security guard, took advantage of the situation and changed hands to carry the luggage, without giving Cheng Yan a chance.

After walking a few steps, Cheng Yan heard the security guard muttering, "Another guy who grows up and cheats on my sister."

Cheng Yan's face darkened, and Mu Mu raised his chin at him, smiling like a villain.

The old campus of Jiangcheng University is located in the urban area and covers a small area. The mental health center is in the northeast corner of the school. It is a three-story red brick building. Next to it is the new six-story building of the Department of Biology. Two buildings are on the second floor. The locations are connected by a corridor.

Dr. Cheng Yan holds a degree in neurobiology, and this time he came back to work as a researcher in the Department of Biology.Today was the day of registration, and the road was crowded with pedestrians. The two walked for a quarter of an hour from the south gate of the university to the southeast corner. He looked at the time and saw that there were only 10 minutes left before the nine o'clock appointment with the leader.

Walking between the two buildings, he stretched out his hand to Mu Mu: "I'll report first."

Mu Mu pressed the suitcase and did not put it, and mouthed with a smirk: "My sister."

... This time she has directly evolved from Senior Sister to Sister. It seems that she is determined to take back all the embarrassment she got from Cheng Yan early in the morning.

Cheng Yan didn't bother to waste any more words, and was about to forcefully take back his own suitcase, when he saw someone walking by and called Mu Mu "Senior Sister" in a low voice.

It's about time.

Mu Mu was taken aback for a moment, and then smiled, "Hey, Dong Xing, come to school so early again."

The person who came was a boy, about the same height as Cheng Yan, wearing a black short-sleeved T-shirt, probably a student from the department.Seeing that Mu Mu was holding a suitcase in his hand, he naturally reached out and took the suitcase into his hand: "Senior Sister, I'll help you carry your things."

Mu Mu didn't intend to stop him at all, he let the boy lift up the suitcase, said "good junior" with a smile, and deliberately turned his head to look at Cheng Yan.

Cheng Yan was startled: "That's me..."

The boy ran very fast, and in the blink of an eye, he had already walked up the steps leading to the red brick building. He opened the door and waited for Mu Mu, obviously not hearing what he was saying.

Cheng Yan waved his hand dejectedly, not in the mood to look at Mu Mu's almost laughing face, turned and walked into the biology building.

Hurrying up to the sixth floor, Cheng Yan stepped out of the elevator, straightened his shirt collar, and knocked on the door of the department head's office.

The head of the department looked at him and said with a smile, "Xiao Cheng, you're quite punctual."

Cheng Yan glanced at the clock on the wall, it was [-]:[-].

"Mr. Wang, I'm sorry." He bowed his head and apologized.

The dean of the department didn't change his smile, and said quite kindly: "It's okay, you just came back, there is still a jet lag, and you were supposed to come over in the afternoon."

Cheng Yan's heart skipped a beat.

Wang Yongchun, the head of the Department of Biology, is about to retire. It is said that his teachers and students are notoriously strict. Even Xu Mowen, who usually doesn't talk about these things, reminds the process in a roundabout way.Today's performance, if the rumors are not wrong, must be an ominous sign.

Cheng Yan guessed it right, Wang Yongchun first said a few words in official language, and expressed his warm welcome to young talents like him who came back to support the scientific research and development of the motherland with the qualification of the National Thousand Talents Program, and then talked about him and Xu Mowen The polite words finally cut to the point.

"Xiao Cheng, it's like this." Wang Yongchun made him a cup of tea, "There has been a slight change in the department's personnel arrangements this semester. The old professor who said he was retiring before has applied for an extension of his retirement, so that, the office arrangement is the same. It's a little difficult."

Although the Department of Biology occupies these six floors, plus two floors underground, most of the site is dedicated to various laboratories, leaving little space for the office area.

Cheng Yan expressed his understanding: "It's okay, Teacher Wang, I can squeeze with other teachers."

Wang Yongchun looked embarrassed: "This is also a bit difficult."

Can't even squeeze out the space?Cheng Yan was taken aback, thought for a while and came up with the narrow corridor of the elevator, wondering if he could still work in the corridor, or go directly to the underground animal room to compete with the monkeys for territory?

Wang Yongchun: "So I just said hello to Mr. Xu this morning. He said that there are still vacant offices in the building next door. You can go there first this year."

Cheng Yan instantly understood what the email he missed this morning was about.

Wang Yongchun patted him on the arm: "You are familiar with the environment over there, so it's a good thing? I promise I will vacate the office for you in a year."

Cheng Yan smiled and nodded: "Well, thank you Teacher Wang, this arrangement is quite good, please take your troubles."

When he came out of the department head's office, he didn't even go to see the experimental equipment that he would use later as planned, and walked out of the biology building without knowing it.

In front of you is the small three-story building. The brick red wall is the same as before, and the color has not been washed away by time.There is a large shadow on the left wall, it should be those creepers, which have been occupying the old territory for ten years.

Cheng Yan walked up the steps slowly, feeling a sense of absurd fate in his heart.

In the past so many years, Xu Mowen asked him several times if he wanted to do psychiatric research as well.It was Cheng Yan who insisted on going his own way. He filled in biology when he was in college, rejected Xu Mowen's recommendation letter when he applied, and firmly chose to be a neurobiology tutor.

It's not that he doesn't know that Xu Mowen has high hopes for him and sincerely hopes that he can be his student.

Cheng Yan didn't know why he refused to choose this path, but he was probably just like what Mu Mu said, he was a rebellious bastard.

The stairs leading to the small brick building were quickly completed, much shorter than in memory.

Cheng Yan stood at the door for a while, until someone opened the door and came out. The door shook violently and bounced back quickly, almost slapping him in the face.

"Even the door hasn't been changed in ten years, so poor." He pressed the glass door in time, only to feel that the little emotions in his heart that hadn't had time to accumulate were blown away by that one.

The bottom two floors of the mental health center are consultation rooms, which are responsible for receiving patients who come for consultation, and the third floor is an office.Most of the professors who visit the center also work in the medical school or the psychology department, and not many of them often work in the building.No wonder Wang Yongchun wanted to kick him here.

There is a small living room on the first floor, and a few patients waiting for treatment are sitting on the sofa, their expressions are usually dull after taking medicine.The intern who was communicating with his family was probably still a young student, and Cheng Yan didn't know him well.

Cheng Yan stood at the entrance of the stairs for a while, and realized that he hadn't obtained an access card, so he couldn't go upstairs at all.I was going to send an email to Mu Mu, but I remembered that my gateway account hadn't been opened yet.

He suddenly wanted to go home.

Well, the keys and luggage are not with me.

Fortunately, someone came out of the stairwell at this time, and when he saw him, he called out, "Cheng Yan?"

Seeing a savior, Cheng Yan stepped forward excitedly, "Teacher Fan!"

Fan Mingfan is Xu Mowen's old colleague. He has been in the mental health center for more than [-] years, so he naturally recognizes Cheng Yan who used to hang around here like Xu Mowen's follower.

"It's really you, so I said you look familiar." Fan Mingfan raised his eyes and looked at Cheng Yan, "After five years abroad, his appearance has changed a lot. Lao Xu is not here, are you coming back to see your classmates?"

Cheng Yan smiled: "I graduated and came back to find a teaching position."

Fan Mingfan was very pleasantly surprised: "Let me just tell Lao Xu, you look like a good seedling, and you are so interested in scientific research, you will come back here sooner or later!"

Considering who usually comes to "here", this doesn't sound like a good word at all.Cheng Yan explained: "Teacher Fan, I'm in the Biology Department..."

Fan Mingfan misunderstood what he meant: "It's not bad to have a temporary job in the Department of Biology. It's richer than the Department of Medicine. It's good to work hard when you come here. If you have any questions, come to me at any time."

Cheng Yan thought about the fact that he usually stayed in this building, not seeing up and down, and it was hard to make sense if he didn't work part-time in the center, so he could only thank with a wry smile.When Fan Mingfan went to the consultation room, he had the opportunity to sneak to the third floor.

There are several special treatment rooms on the third floor, and another large office. There are no people in it right now. Mu Mu occupies the three tables in the middle by himself. .

There was a sofa in the corner, and a plastic storage box was piled up diagonally on the sofa. The word "Cheng Yan" was written on the box with a marker pen, which was written by himself back then.His suitcase stood beside the armrest of the sofa, which was much more securely placed than the glove box.

Cheng Yan didn't move the suitcase, picked up the glove box first, walked through the big office and went further inside.

There are three separate small offices on the other side of the wall.

Mu Mu looked up strangely and said, "The boss is not here, the office is locked."

Cheng Yan didn't go to the first room with the closed door, but opened the second door with one hand.

Mu Mu jumped up from behind: "Wait a minute, Cheng Yan, don't tell me you changed your mind and came here to stay?"

Cheng Yan just entered the room and turned on the light, put the storage box on the empty table, and said "hmm".

He would never say that he was exiled by the biology department.

Mu Mu turned pale with shock: "Why?"

Cheng Yan didn't even lift his eyelids: "I miss you."

Mu Mu: "Master, I'm going to throw up. Tell the truth."

Cheng Yan: "I heard that postdoctoral fellows must be dispatched by teachers in the department..."

Mu Mu wailed: "I knew you had bad intentions!"

Cheng Yan felt that today finally had a moment of comfort, and smiled slightly: "Sister, we will work together in the future, please take care of me."

Mu Mu was so disgusted that he jumped back a small step, rubbing the non-existing goosebumps on his thin white arms.

At this moment the door was pushed open.

Someone said softly: "Sister, you want a strawberry milkshake."

A somewhat familiar voice jumped into Cheng Yan's ears. He looked up and found the boy who had just dragged his suitcase standing at the door.

The boy was a little surprised when he saw him, and blinked his delicate eyes.

Mu Mu snatched the milkshake from the boy, took a big sip, and pointed to Cheng Yan casually: "Dong Xing, come and see, remember this ugly face of the exploiting class, he is the one I mentioned to you before Damn it, your teacher Xu's baby boy... no, good student."

The boy raised his eyebrows, walked over, and smiled very lightly at Cheng Yan, a shyness appeared on his originally cold face.

"Hi brother, my name is Li Dongxing." He carefully put the bag in his hand in front of Cheng Yan, "I just bought an extra cup of coffee, brother?"

☆、Four personalities ([-])

Glancing at the steaming cup of coffee on the table, Cheng Yan hesitated for a while before accepting it: "Thank you."

Li Dongxing smiled and waved his hands, then turned and went out, remembering to close the door lightly.

"Be good? He is really my dream junior. He is capable and obedient, and also handsome." Mu Mu turned his head to look at Cheng Yan, and clicked his tongue, "It doesn't look like you."

Cheng Yan raised his eyebrows thoughtfully: "Old cows eat tender grass?"

Mu Mu almost sprayed him with a milkshake: "What nonsense are you talking about! I like the calm uncle, Masaharu Fukuyama, Daoming Chen! And tell me clearly, who is old, huh?"

"No one." Cheng Yan silently moved the coffee to a safer place, picked up a wet towel and wiped the table, "The teacher never mentioned to me that he has accepted another student."

Xu Mowen likes to be quiet, and has been studying abroad for many years, so he rarely accepts students. After Mu Mu, he only brought two or three graduate students. Cheng Yan also knows more or less about these people, and has occasionally dealt with them. .

But this boy named Li Dongxing, Cheng Yan didn't know his existence at all.

Mu Mu looked at Cheng Yan's face happily: "Why, you see someone younger than you and more likable than you, is there a psychological crisis?"

Cheng Yan cleared the table without raising his head: "I'm not like some people, I just want to take good care of my junior."

Mu Mu sneered: "Pretentious."

Cheng Yan ignored her and asked, "What grade is he in?"

Mu Mu: "Winter trip? He hasn't entered school yet. He just graduated from undergraduate and is working as a research assistant at the center."

Cheng Yan was taken aback: "Why do you want to be a research assistant?"

Research assistants are neither regular employees nor students, with meager wages and no academic qualifications, but they do more work than ordinary students and most employees.

Mu Mu thought for a while: "Probably because the boss is going out this year. The boss really likes winter travel, and he definitely wants to take the students by himself."

Cheng Yan frowned: "It's still quite a delay."

Mu Mu: "It's your own decision. You don't want to work with the boss. There are plenty of people outside who want to be his students. I think winter travel is also voluntary. If you accumulate experience this year, you will be able to graduate more smoothly in the future."

Cheng Yan responded and didn't ask any more questions.

All the things in the glove box were displayed in a short while, including a dozen books, five or six notebooks, two pens, a purple bamboo pen holder that was worn to a whitish level, and a bunch of keys lying under the box.

"It's just a few things." Mu Mu muttered while helping him arrange the books, "I lost everything I could lose when I graduated, remember to buy anything that is missing, and ask me to borrow it before it arrives, senior sister Very generous."

Cheng Yan twitched the corner of his mouth: "Thank you."

Although he has been making noise all the time, he also knows that without Xu Mowen, the only person closest to him in the country is Mu Mu.

Mu Mu was so flattered that he threw away the towel in his hand and wanted to touch Cheng Yan's head: "Why are you so obedient all of a sudden?"

Cheng Yan dodged the dusty hand, and stuffed the waste paper that had just been cleaned up into Mu Mu's hand: "A good man will do his best, help throw it away."

"I know I have to order people around." Mu Mu rolled his eyes, but still picked up the trash, and wanted to take the coffee from Cheng Yan's table by the way.

Cheng Yan quickly grabbed the paper cup tightly: "Don't move, you haven't drunk yet."

Mu Mu: "Didn't you never drink coffee?"

Cheng Yan: "It's from my younger brother."

Mu Mu curled his lips: "You just pretend to be you."

After speaking, she also left the office.

Cheng Yan turned on the computer and looked at the schedule for the past few days, and then dealt with chores, several hours passed in a flash.The jet lag played a role near noon, and he only felt dizzy and sleepy inevitably.

The cup of coffee was still there, untouched by a sip.It's true that Cheng Yan doesn't drink coffee, it's not that he doesn't like it, but that he gets a headache when he drinks it.He took the cup of coffee and didn't let Mu Mu take it out untouched. He was really putting on a show in front of Li Dongxing, fearing that the first time they met, he would lose face to his junior.

Mu Mu was right, Cheng Yan just loves to pretend.

It's so small that you can talk and laugh politely with others even if you have no interest, and it's as big as [-] degrees high fever and headache, and you don't want to be absent from the school sports meeting.

Cheng Yan has been like this for a long time, not because of gaining fame, but because he is afraid of trouble.He doesn't care about many things, and he doesn't want to get too involved with others. Compared to arguing with others with his true temperament, it's better to put on a humble and gentlemanly appearance.

His performance was too perfect, so many people who were not familiar with him said that Cheng Yan really looked like Xu Mowen's own.

Mu Mu knew his true face because, as Xu Mowen's first student, she had many opportunities to get in touch with Cheng Yan.At that time, Cheng Yan was just in college
