Why am I losing?

How can she be sure she's going to be my friend?

Ke Yuhan was wandering in math class with his head down, thinking about problems.

"Classmate, is there a title in the book that I said? Look at the blackboard! ”

The math teacher clicked on Ke Yuhan.

He stood up at the sound.

"Don't you listen to the explanation?" The teacher asked.

Ke Yuhan lifted his glasses and nodded.

There was a commotion and laughter in the classroom.

"Yo!" The teacher smiled, revealing slightly yellowed teeth, and the folds at the corners of his eyes were gathered together, but the man in his early forties looked old.

The teacher tapped on the blackboard: "I'm quite confident, come on, tell me where is the monotonic interval of this function?" ”

Ke Yuhan glanced at the question on the blackboard: "Teacher, you wrote the title wrong." ”

There was another commotion.

"What?" The teacher looked at the blackboard, glanced at it, and then picked up the workbook he had brought: "No?" What is the wrong copy? It's exactly the same as in the booklet. ”

"Oh, then there must be something wrong with the question." Ke Yuhan's tone was full of confidence.

He felt a tug at a corner of himself.

He turned his head and saw Xu Xuanyue glaring at him frantically.

Ke Yuhan frowned, "What's wrong?" ”

"Classmates." The teacher's voice came from the podium.

"Please explain what is wrong with this topic." There was a sense of oppression in his tone.

"Okay." Ke Yuhan responded.

Xu Xuanyue, who was about to blink out the contact lenses on the side, patted her head and expressed helplessness.

"So, here I go. This problem allows us to calculate the monotonic interval of this function, but from the perspective of the open and closed state of the interval of the defined domain it gives, it does not meet the requirements of the original problem. The first is the case where the denominator must not be zero, which defines the domain ......"

Xu Xuanyue couldn't understand what he was saying at all, and some of the other students in the class were also in a fog, and when they first came into contact with the large span of high school mathematics knowledge, the polarization in the class was revealed at a glance.

Su Xin carefully analyzed Ke Yuhan's words below, his expression gradually changed from solemnity to surprise, and finally he suddenly felt relieved.

"Su Xin, do you understand? I'm a little dizzy. Xia Yuan, who was dazed on the side, leaned over and asked.

"Well, I think he's right, and it's hard for the teacher to answer now."

After Ke Yuhan finished stating his thoughts, he said as usual: "The argument is complete." ”

The teacher's expression became solemn, and he was thinking, thinking about how to get himself down this step.

"You're right......" he grimaced, intending to take it hard.

"Oh! That's right. A girl's voice came from the class.

"Why didn't I think of it, or I would have reminded the teacher, oops." Xu Xuanyue continued to follow her words, clapping her palms and posing with remorse.

Ke Yuhan cast a puzzled gaze at her.

The teacher cleared his throat as if grasping at a life-saving straw: "Yes, why is this student the only one who thinks of it?" He turned the finger at the rest of the class.

"What's your name?"

"My name is Ke Yuhan."

"Well, that's good, Ke Yuhan. But how did you look absent-minded just now? ”

Ke Yuhan replied: "I previewed it. ”

There was another commotion in the class, followed by a crowd of admiration and prolonged applause.

The first thing after the class bell rang, Xu Xuanyue took out a pack of medicinal tea from her schoolbag, and planned to get up and go to the water dispenser in front to get hot water.

Ke Yuhan blocked her way.

"Can you answer me a few questions? Xu Xuanyue. ”

Xu Xuanyue looked at the long queue that had already formed in front of the water dispenser because Ke Yuhan blocked the way, sighed, but was inspired again.

Xu Xuanyue slowly sat down with her legs crossed, stretched out the water cup in her hand to Ke Yuhan, tilted her head and smiled evilly: "You help me get a cup of hot water, and I will answer your question." ”

Ke Yuhan picked up the water glass and walked to the front of the team, and obediently lined up.

This surprised Xu Xuanyue, he actually agreed to such a waste of time, and he couldn't help but wonder what kind of earth-shattering questions he would ask with his character.

It's been three days! It's been three days! Ke Yuhan's heart was filled with excitement at this time, and he finally mustered up the courage to ask that sentence, tomorrow is the weekend, if he has to wait for two more days, he will really be stunned.

At this time, the smell of Chinese medicine rushed into his nostrils, and he looked down and saw the medicine bag in the cup.

Four minutes later, Ke Yuhan returned to his seat and carefully placed the cup in the middle of Xu Xuanyue's table, and the smell of the soaked medicine in the medicine bag spread more strongly in the air.

"You...... What kind of medicine is in the cup? ”

"That's what you want to ask?" Xu Xuanyue said in surprise.

"Oh no, it's not."

Xu Xuanyue picked up the cup and clenched it in her hand, blowing air.

"Say, what do you ask?"

"On Monday night, you said we could be friends. On what basis do you judge? ”

"On the basis? I don't, I just think so. ”

"What?" Ke Yuhan's expression instantly became sluggish.

"yes, how do I know what's going to happen in the future, I just believe we can get along."

Ke Yuhan looked at Xu Xuanyue's casual expression, and his eyes were full of unwillingness.

"With such rigor of you, I actually lost the gamble that day?"

"Hmm...... It's just a coincidence, haha. ”

Xu Xuanyue took a sip of the brewed tea, so bitter that she stuck out her tongue.

Ke Yuhan's definition of the girl in front of him was refreshed again, and he suspected that Xu Xuanyue was suffering from split personality.

The class bell rings.

After talking about "Qinyuan Spring Changsha" for a while, the Chinese teacher took out the roll call.

"Next, let's talk to your classmates about your analysis of the author's psychological state at this time." She looked up.

When the teacher takes the roll call, bowing your head to avoid direct contact with the teacher's eyes is a very effective way to avoid it in the eyes of your classmates. Maybe it's just a psychological effect, but when the person who is pointed out is not me, I still breathe a long sigh of relief, and secretly sigh that this method is effective, and my heart that can't stop beating faster will slowly slow down. It's like a convention that has been passed down from generation to generation.

The teacher glanced through the class from left to right, and most of the hair on the top of the head was jet-black, as if his face was hidden.

The teacher suddenly noticed a person.

With this level of rigor I'm going to lose? How could I lose? Ke Yuhan was still puzzled at this time, staring ahead with a confused look.

"Just the male classmate in the third row by the window on the left, you can answer."

Ke Yuhan won the lottery again.

He got up and looked blankly at the teacher.

"Analysis of the Psychological State of the Author of "Qinyuan Spring Changsha"." A hint as thin as a mosquito sound came out of Xu Xuanyue's mouth, and she covered Ke Yuhan again.

"I don't know." Ke Yuhan replied.

"It's okay, it's okay to say something wrong, just talk about your understanding."

"The character's psychological state is irregular and varied, how can he deduce between the lines the thousands of thoughts he wants to express? Theoretically, it cannot be analyzed for the following reasons......"

Xu Xuanyue frantically pulled the corners of Ke Yuhan's clothes, almost tearing his clothes, and couldn't stop his discussion.

The classmates in the class were stunned again, witnessing the transformation from a genius to an idiot.

"Argument complete."

Xu Xuanyue racked her brains to think of a way, and finally came to the conclusion: "Love can't help." ”

The Chinese teacher was on the podium, clutching a book, not knowing what to do.

"Classmate, what's your name?"

"My name is Ke Yuhan."

In short, Ke Yuhan became a well-known object to all the students in the first class that day, so much so that they were familiar with this name many years later.
