He Chao was still looking at the problem, following the conditions highlighted by Old Wu with a red chalk, and combining the data, several different problem-solving ideas emerged in his mind.

The knowledge points taught in this class were actually very common, but when small concepts were tested together in a problem, the difficulty immediately increased.

He Chao couldn't help but want to tear a piece of paper and make some drafts.

Xie Yu glanced at him and vaguely felt that He Chao's concentration on the blackboard was more focused than when he was playing games earlier.

He Chao didn't have much passion for playing games, lazily clicking a few times without much effort.

Compared to being passionate about playing, it was more like he was just killing time.

His skills were not bad, with many fancy moves. Wan Da and his friends often came over during evening self-study and shouted, "Brother Chao, can you teach me? Which tier are you in?"

He Chao always said, "No, I want to play doubles with my desk mate romantically."

Wan Da persistently tried to get a spot as a good friend, "With Brother Yu? That's a death sentence for solo play. Don't you want to experience the feeling of having a teammate?"

Thinking about this, Xie Yu reached out and lightly tapped He Chao's phone screen.

On the game interface, "Handsome He" dodged attacks, swung his sword and flashed back, dragging his remaining health to the side.

Xie Yu withdrew his hand and asked him, "What are you staring at?"

"First, look at these prerequisites, combine them with the problem," Old Wu emphasized, and drew a picture while tapping the ruler on the blackboard. "Take a few minutes to think about it..."

After Old Wu finished speaking, he wanted to call someone up to the blackboard to solve the problem. He looked around and saw that only Xue Xisheng was trying hard to analyze the problem. He said, "Student representative, why don't you come up and give it a try?"

Xue Xisheng raised his hand to adjust his glasses and walked up to the blackboard. He wrote "Solution" in the upper left corner of the problem, neatly and precisely.

He Chaoan quickly fed some healing medicine to his game character, but didn't know what to say afterwards.

He couldn't just say: Old Xie, this extension problem is pretty simple. I can come up with three different solutions in one minute. Do you want to hear them?

Fortunately, Xie Yu didn't continue to ask.

Xie Yu wrote down a few steps on his phone's memo, organized his thoughts, and then deleted them. He opened the calculator and began to solve the problem.

Neither of them understood much about love, but there were many people around them who were already in relationships.

Just from what Wan Da said, you could circle the school twice with all the couples. Which class has another new pair, who broke up with whom in that class, and the reasons for the breakups were all kinds of trivial things, as if they were just playing around.

The biggest scandal was last year, and even people like Xie Yu who didn't listen to gossip knew about it.

There was a girl with excellent grades, the representative for Chinese class, who would give a speech at the annual parent-teacher conference about her learning experience. She looked very obedient. Later, she fell in love with a transfer student who spent all his time in their class.

As they were dating, the transfer student wanted to break up, but the girl refused.

When they broke up, they made a big scene in the hallway. The transfer student said painfully, "We're not suitable for each other. Let's just end it. When you have difficulties in your studies, I can only watch you suffer, but I can't help you with anything."

"I can ask the teacher if I have any questions-"

"No, you don't understand. This is not something that can be solved by just asking the teacher. It's a gap between us that cannot be bridged."

"..."

This incident is still widely circulated on the online forum of the No. 2 High School, with many likes and comments.

Xie Yu figured out the answer and cleared his memo, thinking to himself that there was no need to rush, he could take his time.

Little did he know that He Chao was also thinking: No, the gap is too big, I'm afraid the little friend will feel inferior.

Xue Xisheng used the most complicated method, filling up half of the blackboard, and even made a mistake in the final step by forgetting to consider the range of values.

As class was nearing its end, Old Wu briefly explained this extension problem.

He Chao continued playing the game, but couldn't resist looking up at the blackboard while it was loading. After finishing two rounds, he realized he had completed all the tasks he could do and was about to log off when he received a team invitation from Shen Jie. He instinctively accepted it.

Wu Zheng reminded the class representative to go to his office later to pick up their homework, then packed up his things and went to the next class.

Xie Yu had just put away his phone when he heard He Chao curse next to him.

Xie Yu thought he had lost the game, but when he looked closer, he saw a long-haired female character in a skirt on He Chao's phone screen.

He Chao had earphones in his ears and seemed to have turned on the team voice chat. Xie Yu reached over and pulled one out, then put it in his own ear. He heard a soft voice of a girl saying, "I'm not very good at playing, can you protect me later?"

Xie Yu twirled the headphone cord around his finger and drawled, "Life's been pretty good huh, bro. Bringing a girl along."

He Chao couldn't express the bitterness in his heart.

Earlier, Shen Jie had invited him to join the team and help out with someone, saying it was related to his lifelong happiness. But then his stomach started hurting and he needed to go to the bathroom to take care of his physiological needs.

Before He Chao could refuse, Shen Jie had already pulled the girl into the team and ran off.

"It's not what you think."

Xie Yu's words were dripping with sarcasm. Although it felt good to see his boyfriend jealous, He Chao immediately explained with his mic off, "I don't know her, she's brought by Shen Jie. I really don't know her."

Xie Yu retorted, "If you don't know her, why did she ask you to take care of her?"

"He went to the bathroom and asked someone to take care of her for a while."

Xie Yu sneered, "Why did he ask you instead of someone else? Seems like you have some experience?"

He Chao was at a loss for words.

Xie Yu wasn't really going after the matter.

He just saw He Chao explaining so earnestly and continued with a few more sentences. After he finished, he didn't let him leave the team, but instead took the initiative to press start: "Hurry up and carry her along, class is starting soon."

That girl was still talking, but He Chao didn't listen to anything she said.

His mind was full of: Damn, my boyfriend is usually cold, but occasionally showing a little attitude is so damn cute.

That girl, who was playing the game, had emoticons as her username and was obviously interested in He Chao, even though he didn't say much from beginning to end.

Emoticons: "Big brother, are you also from No. 2?"

Emoticons: "Do you have a girlfriend?"

Having followed Xie Yu for so long, He Chao had learned some real skills, but he still couldn't match Xie Yu's level of fierceness. Xie Yu would always start with the four words "What's it to you?" So He Chao said, "I have a boyfriend."

"..."

Finally, the game ended. He Chao immediately quit, afraid that Emoticons would drag him into another round.

Xie Yu leaned on the table and looked at him. "Aren't you afraid she'll tell Shen Jie?"

He Chao unplugged his headphones and looked at the schedule. There was only one class left. "She doesn't need to tell him. Shen Jie already knows."

The classroom was very noisy.

Liu Cunhao and Wan Da were playing around. When they passed by, Liu Cunhao's waist hit the corner of Xie Yu's table, causing it to shake slightly. The vibration sound entered Xie Yu's ears.

Xie Yu blinked. "He knows?"

"When we were playing games during the autumn outing," He Chao said while flipping through his text messages, "let me check. You can just read it?"

Xie Yu took the phone and glanced at it. He saw Shen Jie anxiously asking several questions and the proud words written by He Chao in response.

It was a firm declaration, even with a hint of arrogance between the lines.

- Xie Yu, my boyfriend.

Xie Yu never expected He Chao to be so direct.

Their relationship was not as convenient as others, where they could openly declare their status or act recklessly around school as long as they avoided the teachers.

After thinking for a moment, Xie Yu realized that he would have done the same thing if he were in He Chao's shoes.

- He Chao, this idiot, my boyfriend.

When Shen Jie finished using the restroom and returned to his classroom, he stopped by Class 3 on the way. He snuck in through the back door and patted He Chao's shoulder, asking, "How did it go, did you finish carrying her."

"What do you mean, how did it go?" He Chao kicked him directly and said, "I have a boyfriend now, and you pushed me into a pit of fire."

Shen Jie dodged and said, "I only came to find you because you have a boyfriend...I wouldn't trust anyone else."

He Cha threw a bottle of mineral water back at him.

"Fine, I won't come to you next time."

Shen Jie picked up the bottle and put it back. "I'll go find your family's Old Xie, I trust him too."

He Cha said, "...I think you're trying to get yourself killed."

Shen Jie didn't have any unusual reaction to the two of them, as if he had already digested everything he needed to in the past few days.

It was quite natural.

"What do you want from me?" Xie Yu asked. "Do you want to experience a two-people solo game?"

Shen Jie: "..." He almost forgot about this lone wolf player.

After causing a commotion for a while, when the bell for class rang, Shen Jie went back to Class 8. Before leaving, Shen Jie paused and noticed the red string bracelets on the wrists of the two people. He glanced at them and said without preamble, "It's quite good, nothing special actually, and I'm not surprised at all."

After all, with his brother's lack of emotional intelligence, it was already a miracle.

He Chao smiled and said, "Get out of here."

After the last class, the people rehearsing the program stayed for an extra half hour to continue practicing their dance.

Most of the people in the classroom had already left, leaving only a few students on duty.

Xu Jing played a song on the classroom computer, which required two people to coordinate and form a couple. The movements were quite ambiguous, with a waist-hugging section.

Xu Jing and Xu Qingqing demonstrated it once.

He Chao stood behind, with his hand resting on Xie Yu's waist, holding him in his arms and not wanting to let go. "Are you going to the evening self-study later?" he asked.

Xie Yu was still thinking about the previous movement and instinctively asked, "Aren't you going?"

"What for?" He Chao said, "I want to go back to the dorm and do something else."

"..."

Xie Yu noticed that He Chao had become increasingly skilled at making suggestive remarks lately.

Luo Wenqiang was of a large build, and being hugged by another boy of similar size made him look particularly strange. Xu Jing had originally wanted to guide the two of them, but ended up almost laughing out loud.

Luo Wenqiang sighed stiffly, "Jingjing, you didn't mention that there was this movement before."

"Relax a little, look at Brother Chao and Brother Yu, how natural they are..." Xu Jing said.

Wan Da waved his hand, already seeing through it all. "They're different."

At last, when it was all over, a group of people formed a discussion group called the "Unbeatable Most Handsome Squad" to share instructional videos and rehearsal schedules.

Even during evening self-study, the group never stopped buzzing like a group of trainees waiting to debut, with notifications constantly shaking their phones.

Everyone was eager to show off their charm on stage and become famous.

[Luo Wenqiang]: Last year, someone from the class next door played the guitar and got a lot of girls adding him on social media

[Luo Wenqiang]: I don't need that many, just one is enough.

......

After showering and drying his hair, Xie Yu came out to find that He Chao had 99+ notifications. With wet fingertips, he swiped through them and saw a familiar green icon at the bottom of the screen.

It was a notification for the "Trivia King Battle".
