In the center of the simple mourning hall hangs the portrait of the deceased. The woman in the black and white photo looks very young. She had few relatives and friends when she was alive, and only the neighbors nearby came to offer condolences after her death.Her only son stood beside the spirit, bowing to every guest with a blank expression, his expression was strangely calm.

Several middle-aged women whispered together.

"What a miserable person. Married to a man who gambled and drank heavily, and raised his son through hard work alone. Seeing that he was enjoying life, how could he have contracted this disease in a blink of an eye, and passed away in a few years, hey."

"The saddest thing is that it has been a week since my mother passed away, and I haven't shed a single tear as a son. Could it be that he was beaten stupid by his father when he was a child?"

"Back then, his bastard father would take his anger out on his son whenever he lost a bet. The children could hear the whole building crying. I secretly called the police a few times. Then nothing happened. I thought he changed it. Who knows? Seal your mouth and continue beating until you're dying, it's really vicious. If the mother didn't run out desperately to ask us for help, the child would have almost died."

"I'm not a thing, but the boy is too hard-hearted. Could it be that he inherited his bastard father?"

"If we hadn't watched him grow up as children, we would have thought that the one over here was a passer-by, and the one over there was her own son."

The person they were talking about was hiding alone in a remote corner of the mourning hall, crying heartbroken. The focus of everyone's attention was not on the real family members of the deceased, but on him.

The voices of the neighbors in the neighborhood reached Ling Chuan verbatim. He sighed helplessly, walked to the corner, lowered his head and rummaged in his pocket, and found a handkerchief.

"Wipe it, don't cry, if you cry again, I will suspect that you are my mother's real son."

Lu Nan cried uncontrollably, Ling Chuan had no choice but to wipe his tears with his own hands.

"I told you not to cry, look at you, your eyes are swollen like walnuts."

"You...don't be too sad..." Lu Nan said in tears, obviously he was the one who cried the most, but he comforted others instead.

Ling Chuan shook his head: "It's been three years since my mother was diagnosed with the disease. Maybe it's because I've been mentally prepared for a long time. When this day actually comes, I'm not as sad as I imagined."

Lu Nan's crying gradually stopped, but he still sobbed from time to time.It was only then that people realized that, ignoring those red and swollen eyes, this man was actually a very handsome man, with a tall and straight figure and elite attire, making it hard to believe that he was the same person who cried bitterly before .

An unwelcome man broke in and caused quite a commotion in the mourning hall. Everyone who knew him at the scene showed contemptuous expressions on their faces.

Ling Chuan was still calm, but Lu Nan stepped in front of him with a stride. Ling Chuan's gaze drifted down, only to see Lu Nan's trembling hand that was deliberately hidden behind him.

"What are you doing here?" Lu Nan asked, holding back his fear.

The man replied bluntly: "This is my family's business, why should you take care of it?"

"Xiao Chuan's business is my business. He doesn't have a family like you at all." Although Lu Nan forcibly restrained, the slight tremor at the end betrayed him, and keen people found that he was afraid.

"He was shot by Lao Tzu, so it's okay if you say it's okay?" The man sneered, his vulgar words were disgusting.

Ling Chuan took a step from behind Lu Nan, and calmly faced his biological father.

"Exactly, I also have something to tell you. Dad, this is the last time I will call you Dad. Now my name is Ling Chuan. From the day I changed my surname, I have nothing to do with you. My little one I was afraid of you at the time, and I never dared to disobey your words. But now it is different, I have grown up, and I am no longer the cowardly and incompetent child who let you beat me, and you can no longer use threats and intimidation, from I can get anything from here. From now on, you and I will have nothing to do with each other. Mom is gone, so let her go in peace. "

The man sneered at his son's words: "Don't think that you are not my son because you took the surname of your short-lived mother. You want to sever the father-son relationship with me? All right, give me my share of the inheritance. I don't want to be alone."

Before Ling Chuan could speak, Lu Nan became angry: "Are you shameless? Auntie earned so much money and you gambled it. When did you take care of Auntie and Xiao Chuan? Auntie was sick and you disappeared without a trace. Auntie Are you still willing to ask for money after you leave?"

Neighbors who couldn't see it anymore followed suit, and the man had to restrain his arrogance when he saw that the other party was crowded, but his attitude was unrelenting: "I checked, and the house has not been sold. Now that your mother is dead, the house is a mine!"

Lu Nan still wanted to get angry, but Ling Chuan held him down calmly: "The house is where I grew up, and despite your bad past, it is also the last memory of me and my mother. I didn’t sell it when I couldn’t pay the medical bills, and I won’t give it to you now.”

"Do you think you can send me away by saying that?" The man pointed at Lu Nan, "I remember your concubine is still a lawyer, he should know who this house belongs to better than you. Hand it over, lest everyone see you in court!"

His words provoked a mocking laugh from Ling Chuan, and he was irritated by the obviously contemptuous laughter: "What are you laughing at? Your father and I are also people who understand the law!"

"That would be great. Since you understand the law, you must be clear that husband and wife not only own joint property, but also jointly bear debts, right?" Lu Nan tremblingly took out a piece of paper from his arms and unfolded it in front of the man, "In order to give Auntie is treating the disease, the house here was mortgaged by usury three years ago, now that Auntie is gone, you are the first debtor, please pay back the money immediately!"

"Repay the money!" "Repay the money!" The onlookers echoed.

The man became angry from embarrassment: "You are talking nonsense!"

"Didn't you want to see the court? Am I talking nonsense, you will know when you go to court." Lu Nan picked up the IOU, "But I want to warn you, if you continue to pester Xiao Chuan, it will be based on what you have done in the past For any crime, I can let you go in and squat for a few years. It is easy to see the court, but I am afraid that I will have to go to the prison to see you later. "

This righteous warning was slightly compromised because of Lu Nan's lack of momentum, but it still had the desired effect. The onlookers pointed at their noses and scolded him: "Either pay the money, or get out!"

The man knew that he was no match for so many people in a fight, and Ling Chuan was backed by the lawyer he hated the most. Now that he was at a disadvantage, he could only put down a harsh sentence angrily: "You two wait for me, sooner or later this house will be destroyed. Every day is mine!"

The corners of Ling Chuan's mouth turned up, revealing an inappropriate and weird smile.

"You can still laugh when your mother is dead. I think you are the real wolf." The man cursed him viciously, "I really committed a crime to give birth to you, a bitch who is fucked by others."

Ling Chuan looked calm, he didn't know if he was pretending to be watertight, or he was really indifferent, but Lu Nan beside him turned pale and bloodless.

"If you have said enough, please leave from mother's grave." Ling Chuan gave the order to evict the guests.

After driving away the uninvited guest, the others left one after another after a few simple words of comfort to Ling Chuan, leaving only Lu Nan still here with a bad expression on his face.

Ling Chuan asked him with a smile: "I don't care about him anymore, why do you still care so much about what he says?"

Lu Nan clenched his fists: "Because... because I don't want him to talk about you like that."

"Can you believe it? No matter what he says now, he can't hurt me anymore. Probably because he is really just a small passerby in my heart, even more insignificant than passersby."

Lu Nan lowered his head: "I believe it."

Silence fell between the two, and neither of them knew what to say next.

"Come here by car?" Ling Chuan broke the embarrassment.

"Ah."

"downstairs?"

"Ah."

"Then," he paused, "I'll see you off?"

"……Um."

The two walked down the stairs silently side by side. There was no elevator in this old residential building, and the exact same corner circled seven times clockwise before reaching the end.

Lu Nan's car stopped on the south side of the road, and the two stopped on the north side of the road.

"arrive."

"Ah."

Lu Nan didn't leave for a long time, the two were relatively silent, Ling Chuan suddenly said:

"How long has it been since we broke up?"

"Three years."

"Three years ago, the relationship between you and me was exposed. My mother strongly opposed it, but I refused. She went to the hospital in a fit of rage, and found out that she had a tumor in her brain." Ling Chuan couldn't help but smile bitterly, "What a clichéd plot, In order to let her recuperate at ease, I proposed to break up, and you agreed."

"I know you don't mean it, I just don't want to embarrass you."

"Yeah, but I always feel that my mother's illness was caused by you and me. After that, I deliberately avoided seeing you. In fact, I know very well that these two things have no cause and effect. You were innocently angered by me and took over me at a high price. house. I know every sum of money you have given me secretly over the years. Without you, my mother could not have persisted for so long, and today it is not so easy to get rid of that scumbag. You have been helping me, but I have been I owe you."

"Don't say such foreign words, it will make me feel that I have become a passerby in your heart."

"Okay," Ling Chuan pursed his lips, and changed the subject, "How are you doing now, do you have... a new partner?"

"Still single."

Ling Chuan bit his lower lip, struggling: "I'm thinking, if it's possible... I mean, if you're willing... Is it possible for us to start all over again?"

The light in Lu Nan's eyes was lit, he pulled the person opposite into his arms, and buried his head deeply into his neck, as if the whole world had been lost and regained.

Ling Chuan returned to his long-lost embrace. He slowly raised his arms and wrapped them around his broad back.

"It's not starting all over again." Lu Nan said in a muffled voice.

"what is that?"

"It's unfinished."

Ling Chuan closed his eyes, and felt it quietly for a moment, until he felt something strange, and he struggled to break free, only to find that Lu Nan's eye sockets were red again.

"Why are you crying again?" Ling Chuan took out a handkerchief to wipe the corners of his eyes again, "You're crying so much now."

After wiping his tears, he simply folded his handkerchief and stuffed it into Lu Nan's breast pocket: "This is yours, remember? When I used to cry, you used it to wipe my tears. But now, you seem to Need it more than I need it."

Lu Nan clasped his wrist and lowered his head to kiss his mouth. Ling Chuan dodged with a smile, and kissed him passionately on the side of his face.

"No, there are too many people."

Lu Nan couldn't help himself: "If we go back now, will it be an offense to Auntie?"

Ling Chuan took his hand and turned away. The two circled around the same corner counterclockwise seven times and returned to the starting point.

As soon as they entered the door, they kissed selflessly, passed through the mourning hall, broke into the bedroom, and both fell on the bed again, vowing to make up for the three years they missed.Lu Nan's fiery lips wandered over Ling Chuan's cheeks, forehead and hair tips. The hands raised above his head couldn't help clasping their fingers together, breathing lingeringly, their limbs intertwined, and the white sheets folded under them into a gully of time.

The moment the vacancy was filled, Ling Chuan felt the moistness from his cheeks, he opened his eyes, there were still crystal teardrops hanging on Lu Nan's thick eyelashes.

"Don't cry." Lu Nan held Ling Chuan's cheek pitifully, carefully licking off the salty liquid, "Xiao Chuan, don't cry."

Ling Chuan couldn't help laughing, and also held his face: "Obviously you are crying, and you want me not to cry."

"Xiao Chuan doesn't cry." As if he didn't hear it, Lu Nan repeated it again, buried his head in his neck and gnawed carefully, and the place where the eyelashes brushed was wet all the way.

"I don't cry." Ling Chuan rested his hands on the back of Lu Nan's head devoutly, raised his head, and felt the beauty of life connection with satisfaction, "I will never cry again."
