The temperature is rising, the dead branches are sprouting green shoots, and the black windbreaker that wraps the trees in winter has long been gone, and it has been plucked by the campus sanitation workers at some point, revealing the ugly appearance of the old trees that have been eroded by a cold winter.

When everything is recovering, the students on the campus of Bode Middle School have changed into spring uniforms, and the students are light and energetic, making the campus more flavorful of spring.

Su Wen keenly perceives the changes of the seasons, and he also has a delicate view of the changes of some people around him.

Since last Friday in the music activity room, Song Yuanzhi mentioned that Song Yu's mother would return to China at the end of the month, Song Yu suddenly became abnormal, and it has been a week in a row, from time to time in a trance, and from time to time to come to a composure.

Su Wen sat in the front seat of the boys, sometimes asked Song Yu a few difficult math problems during class, the boys talked and talked, and when the girls suddenly realized and asked if the final solution was correct, the boys were blindfolded with a pair of unfocused eyes, as if they fell into a daze of fugue. The girl called the boy's name a few times, and the boy looked at the girl with a pair of ignorant eyes, and came back to his senses and asked, "Where did you just go?" ”

Su Wen couldn't cry or laugh, but he was also in a trance of doubting the boy's expression.

Except for asking the boy for math problems during recess and finding him in a daze, the same is true in math class. You know, the math teacher likes to call his protégé the name the most, and get up to solve a typical problem that few students in the class can solve at once.

Song Yu has always been a "life-saving straw" for the math teacher, and every time he encounters a problem that cannot be solved, the math teacher always has a confident smile: "Song Yu, what do you think about this problem?" ”

Often, boys read the questions once, and within a few moments, the corners of their mouths are full of confidence, and they write the answers on the blackboard that are as concise as the standard answers in a workbook. Therefore, the math teacher values Song Yu, who is full of thinking for science students in the liberal arts class.

But this tried and tested trick one day also failed, after the math teacher called Song Yu twice in a row, the boy sat firmly like a clock, staring down at the textbook without raising his head, leaving only the math teacher and everyone with a beautiful head.

For the first time, the math teacher was ignored by his proud protégé, so embarrassed that he even stepped off the podium to see with his own eyes whether his proud protégé was "degenerate" and slept like the boys who didn't like to study in ordinary classes. Deng Jiaming, who was at the same table, finally woke up Song Yu, who was distracted by the textbook, with one arm before the math teacher walked off the podium.

The boy woke up like a dream and looked at Deng Jiaming at the same table, Deng Jiaming squeezed his eyebrows and hinted at Song Yu, and the math teacher with a black line on the podium was looking at him with fierce eyes.

Song Yu stood up suddenly, Song Yu, who didn't know which question the math teacher was talking about, blindly flipped through the math textbook for a while, but he didn't know that the math teacher was talking about another math tutorial book in class, and the boy's distraction was fully manifested in this blind flip.

In the end, Deng Jiaming couldn't read it, so he kindly circled the title on his counseling book and handed the counseling book to the boy.

The math teacher, who had been waiting for a long time, saw that his proud protégé had such a situation for the first time, but he calmed down and said patiently and considerately: "Pay attention to listening well in class!" Song Yu, come up and show you the solution to this problem! ”

Dare to wander in his math class and ignore his majesty as a teacher? It's time to kill the sharpness of this proud son of the sky! Song Yu's peach blossom scandal has even been heard of in their teacher group, could it be the rumored early love incident that caused his proud protégé to be distracted in class?

The math teacher had a smile on the corner of his mouth, as if he was confident that Song Yu would not be able to solve this problem.

The girls in the liberal arts class lowered their heads one after another, glad that they were not carrying this black cauldron on their backs, and they also gasped for Song Yu. Song Yu, who usually solves all kinds of math problems, encountered such math problems that can be called perverted this time, plus he was distracted and ignored the teacher's solution prompts, and it was probably not so easy to see the boy's face in a trance.

Alas, poor Song Yu! The girls looked at the boy's delicate face with sympathetic eyes, as if they had sung an elegy for him in their hearts.

Song Yu didn't have time to pick up the tutorial book he pressed under the math textbook, so he hurriedly walked onto the podium with the tutoring book handed over by Deng Jiaming. The open side of the tutorial book was blank as if the owner of the book had never been lucky with the book, except for the ugly black circle on one of the titles.

Uh, why is it the same problem that made him think about it and couldn't solve the correct answer even if he wanted to break his head?

Song Yu remembered his struggle with the problem and wrote several pages of calculus paper, but in the end it still ended in the boy's failure. Song Yu wanted to solve the problem before the math class during the day, but unfortunately he forgot the problem.

Facing the blackboard, Song Yu turned his back to the audience and stared at his eyes, and his right hand raised with white chalk couldn't put down the pen for a long time. As soon as he stepped on the podium, he wrote the free and easy word "solution", and he looked at the boy as if he was mocking.

The classroom was so quiet that only the sound of the students' nervous breathing was the sound of them. Among the students who silently watched the back of Song Yu on the podium, there were still some unwilling students, who followed the prompts of the math teacher in class and performed the problem on the scratch paper over and over again.

Xiao Shijie is also one of them, staring at Song Yu's stiff back, the beautiful finger with distinct knuckles that has been unable to write for a long time is extremely eye-catching, Xiao Shijie is more and more motivated to challenge that problem.

I have to solve the problem before Song Yu can't answer the question and step down, raise her hand and take the initiative to ask Ying to come to the stage to solve the problem, Xiao Shijie thought secretly. Thinking of being able to show off the success of solving the problem in front of Song Yu afterwards, Xiao Shijie's motivation doubled, her inspiration increased by leaps and bounds, and she wrote down the solution ideas of the dragon flying and phoenix dancing on the scratch paper with a wave of the pen.

It's over, the male god is going to be embarrassed for the first time this time. The girls wailed in their hearts.

The math teacher looked around the stage triumphantly, most of the students looked like they couldn't think of a way to solve the problem even if they wanted to, and a few students waved their pens to solve the problem seriously.

Look at his proud protégé who has been immobile for a long time on the podium, the white and angular delicate side face is puzzled, the raised hand has not moved for a long time, and the math teacher is not going to embarrass Song Yu, and is trying to teach the boys, "Song Yu, go down!" Don't be distracted in the next class! As if the pause button had been turned on, the boy kept writing the calculus on the blackboard with his right hand.

Su Wen looked at the exercises in the tutorial book over and over again, trying to solve them in his own way, often less than half of them were stuck there, and when he looked up at the boy on the podium, he was surprised by the extra calculation process on the blackboard in front of the boy that was originally blank except for the word "solution".

In the surprised gaze of the math teacher, Song Yu wrote down two columns of problem-solving processes on the blackboard in a row, and the final answer was exactly the same as the answer simply listed at the back of the tutorial book.

In a different way of thinking, the boy finally solved the puzzle.

The math teacher blinked, looked at the position of the answers on the blackboard in disbelief, and clearly did not believe that Song Yu had written out the results of his preview a few days in advance in just a few minutes.

"Teacher, is there any problem with the problem-solving process?" Song Yu put down the chalk and looked at the math teacher with a bright face, with a respectful look of humility in his eyes.

"No, no problem!" The math teacher was still confused, "That's how this problem is correctly solved!" ”

"Thank you, teacher!"

The boy's face suddenly brightened up with a confident smile after solving the problem, and the girls in the audience were amazed again and again, sure enough, there is no question that can stump Song Yu!

"Brother, you can!" The boy returned to his seat, and Deng Jiaming smiled in surprise.

Su Wen in the audience was no different from other girls, and his eyes flashed with infinite admiration when he looked at Song Yu.

Even Xiao Shijie, who had the best math score among the girls, took a page of her own calculus paper after that math class, pouted and asked Song Yu unwillingly: "Senior brother, can you help me see which step I did wrong?" I think my solution idea is basically the same as yours, how can I calculate a different result? After listening to the teacher's lecture, I still haven't found the crux of the problem! ”

"Senior sister, are you sure your solution is the same as mine?" The boy glanced at the calculation process and pointed to one of the steps before the answer, "Look here, this is a completely extra step!" You don't need to find this auxiliary line, you can only set up obstacles for yourself to find the length of this auxiliary line, just find the height between the auxiliary line and the solid line! ”

Xiao Shijie was stunned when she said this, and nodded suddenly in understanding, "I see!" ”

"Senior sister, you are only a high distance away from success!" The boy's lips curled up with confidence, and his eyes sparkled like stars.

After that adventure in math class, Song Yu repeatedly taught, and in a week's time, he was named by the teacher from time to time in math class, and because of this, the boy was frequently caught by the teacher in a daze. This is true for math classes, but what about other classes?

So Su Wen became more and more puzzled, what happened to him?

Before the self-study began on Sunday night, Su Wen once again caught a glimpse of Song Yu's lonely figure leaning against the wall in the corridor.

Su Wen's heart was inexplicably filled with a certain sense of distress.

A face that is grinning and always with a warm smile on weekdays, why did it suddenly change in a week? Whether in class or after class, frequently wandering in a daze, frequent problems?

In short, everything is too abnormal.

Su Wen looked around like a thief, there was still an hour and a half before the self-study began on Sunday night, and many students did not come to the classroom early. At a glance, there were scattered students leaning on the corridors of each class, so Su Wen walked boldly in the direction of the boys.

On weekdays, when there are many people, walking beside boys in public, Su Wen always has to be a little jealous. After all, Su Wen was too timid, and was looked at by the attention of the strange girl on the road, Su Wen was so ashamed that he was as if he was unclothed, and was executed by everyone's shameful eyes.

The people around him are too dazzling, and their eyes are always pierced by his brilliant light.

Su Wen already understood this truth, when there were few people, it was better to get along with Song Yu than to be awkward under the gaze of others, but to show himself more naturally, just as freely as when he got along with boys in the past.
