The white rose I picked up cried and said she liked me.

It has to be said that Qi Yu is really good at this.

Xu Xi, who had initially felt somewhat inferior about her exam scores, suddenly became confident.

For some reason, Xu Nian felt a pang of sadness in her heart.

He spent the whole night trying to calm Xu Xi down, but once she was in Qi Yu's hands, he managed to appease her with just a few words.

"Then you all study hard, I'm going to get back to work."

Yesterday, Qi Yu replaced Xu Nian for the night shift; today it's Xu Nian's turn to replace Qi Yu.

He waved goodbye to Xu Xi, while giving Qi Yu a warning look.

That look seemed to say, "Behave yourself, or I'll cripple you."

Qi Yu returned his gaze with a deep, enigmatic look, as if to say, "Give me back my beautiful hair."

After Xu Nian left, Xu Xi changed her clothes before inviting Qi Yu to her desk.

Although he was my brother's friend, I wasn't very familiar with him.

Xu Xi was still somewhat wary of Qi Yu, and covered herself up completely.

Qi Yu didn't notice her thoughts. He sat down at his desk, put on his glasses from his pocket, and began to carefully examine Xu Xi's test paper.

As he looked at it, Qi Yu frowned.

"This is incredible, absolutely incredible!"

"What's wrong, Brother Qi Yu?"

Xu Xi felt a little nervous.

"It's really amazing that you could solve this kind of problem."

Qi Yu pointed to a question on the math exam paper.

"This question is about solid geometry, which is entirely from the second semester of the first year of high school. However, your problem-solving approach and steps are correct, but you made a mistake in one step when deriving the answer."

Xu Xi nodded shyly: "I studied some of the first-year high school math on my own, but I found it very difficult. The textbooks are mostly theoretical."

Qi Yu took out a piece of draft paper and explained the problem to Xu Xi again.

Unlike the textbook version, Qi Yu used simple and easy-to-understand language, and when he saw Xu Xi frown, he would pause and repeat it again.

"This type of question is relatively simple. I'll give you another one, and you can try the method I taught you."

......

Night fell, and the clock struck ten o'clock.

Before they knew it, Qi Yu had been talking to Xu Xi for four hours.

Qi Yu was surprised to find that Xu Xi had a high level of comprehension; she could understand most of the question types after just one explanation.

As a result, he explained the questions at a very fast pace, finishing all the wrong answers and knowledge points in three subjects in four hours, and was able to apply what he learned to other problems.

"You're so smart, Xu Xi. If you keep going like this, it won't be long before you've learned all the material for the first year of high school."

Qi Yu praised sincerely.

"It's all thanks to Brother Qi Yu's excellent teaching."

Xu Xi poured Qi Yu a glass of water and was just about to continue listening to the lecture when she heard Qi Yu's stomach rumble.

"Haha, I was in such a rush when I came that I forgot to eat anything."

Qi Yu took out his phone, ready to call Xu Nian.

"I'll have your brother bring over two meals."

"Brother Qi Yu, let me cook for you."

"Huh? Forget it, it's too much trouble."

"No trouble at all."

Xu Xi jumped off the stool, preparing to go to the kitchen to cook some dishes for Qi Yu.

In her opinion, Qi Yu taught her a lot of knowledge and helped her a lot today.

According to my brother, if you ask someone for help, you have to give them a gift in return.

Since I don't have anything to give Qi Yu in return, I might as well cook him a meal as a way of repaying the favor.

"Haha, then I'll gladly accept your offer. I've heard from your brother that you're an excellent cook."

Qi Yu raised an eyebrow, also becoming somewhat expectant.

He originally thought that he would only need to teach Xu Xi for two hours at most before she could stop learning, and then he could go out and get something to eat.

Unexpectedly, Xu Xi showed no signs of fatigue, and because she learned so quickly, she didn't even realize that four hours had passed.

Watching Xu Xi's busy figure in the kitchen and smelling the aroma of food wafting out, Qi Yu suddenly had a strange feeling.

How wonderful it would be if, in the future, after a busy day, I had such a virtuous wife waiting for me to come home, preparing a hot meal for me.

However, this thought only appeared for a brief moment before Qi Yu dismissed it with a wry smile.

"It's ready, Brother Qi Yu, come and have a taste."

Xu Xi brought a dish, a soup, and a meat dish to the table.

"Mmm! It smells delicious, and tastes great."

Qi Yu picked up a piece with his chopsticks and tasted it; his eyes lit up.

No wonder Xu Nian always brags to him about how delicious her sister's cooking is.

I tried it myself today, and it was indeed extraordinary.

"Isn't it too salty?"

Xu Xi felt a little uneasy. When she was sprinkling salt, she accidentally added an extra spoonful, and when she tasted it, it seemed a bit too salty.

"Not too salty, not too salty, just right."

Qi Yu wolfed down his food. People like him, who are out in the wind and rain every day and whose shirts are always soaked with sweat, need to replenish their salt intake.

Therefore, Qi Yu's tastes tend to be relatively strong.

Xu Xi breathed a sigh of relief, then remembered that she hadn't eaten anything that night, so she grabbed a bowl and chopsticks and sat down to eat with them.

After the two finished eating, Qi Yu thought that it was still early and he didn't have to work the early shift tomorrow, so he started giving Xu Xi another lesson.

Xu Nian finished work and went home at 12 o'clock.

"I'm back."

He pushed open the door, but did not see Xu Xi waiting for him at the door.

Xu Nian sniffed and smelled the familiar aroma of the food.

He rubbed his rumbling stomach, knowing that Xu Xi must be preparing something delicious for him.

"Xu Xi?"

But when they went into the kitchen, they didn't see Xu Xi or any hot dishes covered with plates to keep them warm.

All I could see were clean plates and two pairs of chopsticks in the dish rack.

The sound of Qi Yu and Xu Xi talking could be heard from inside the room.

So you're still studying.

Xu Nian touched her nose, looking at the two pairs of used chopsticks, feeling a pang of sadness.

This little guy cooked for Qi Yu, and didn't leave himself a single bite.

......

See you tomorrow, Brother Qi Yu.

"See you tomorrow."

Xu Xi and Qi Yu walked out of the room and saw that Xu Nian had already arrived home and was sitting at the dining table, propping her face up with her hand and staring blankly.

"elder brother!"

"Brother Xu."

Qi Yu stepped forward and greeted them.

"I've heard you say that Xu Xi is a first-rate cook, and today I got to enjoy her cooking. The food is really delicious."

Xu Nian forced a smile and nodded weakly.

"I'll be going now, Brother Xu, see you tomorrow."

"Goodbye, Brother Qi Yu!"

After seeing Qi Yu off, Xu Xi looked at her tired brother and suddenly realized that she had forgotten to cook for him.

"Brother, are you hungry? I'll go make you something to eat."

"Need not."

Xu Nian waved her hand.

"I've already eaten out."

"Oh, okay then."

Xu Xi didn't think much of it and went back to her room on her own.

She's had a lot to say today, so she needs some time to process it all.
