After school the next day.

After Lin Wan struggled mentally for half an hour, she finally came to the lecture hall on the top floor with her schoolbag on her back.

As soon as I entered the door, I saw that Cheng Yu was already waiting there.

He crawled on the table, his face pressed sideways against the table.

Lin Wan lightly walked to the position in the first row and sat down next to him.

He seemed to be asleep.

After falling asleep, he was a little less cold and a little softer.

The long eyelashes hung down quietly like this, and Lin Wan knew for the first time that the original boy's eyelashes could be so long and thick, and under the high bridge of the nose, the thin lips were gently closed.

The person who looks at the face says that the person with thin lips has been affectionate since ancient times, is he the same?

"Have you seen enough?" The eyes opened suddenly, and the dark eyes crashed into Lin Wan's heart like this, making her heart flutter uncontrollably.

"Bring the rolls. He quickly straightened up and sat up.

Lin Wan was bumped and peeked at on the spot, and her originally fair little face turned red instantly.

She rummaged through her bag with her head down, and before she could take it out, she saw a pair of long hands tearing the scroll in front of her.

Spread out in the middle of the table, he flipped back and forth to determine the roughly wrong position, sketched the paper with a pen, helped her circle the mistakes, and then quickly wrote down the calculation steps in the blank space on one side.

"You lose points on this question because you ignore the property that an empty set is a subset of any set, and this question should be categorized according to the nature of A. That is, A is empty and non-empty, look at the diagram I draw, the first case ......"

A deep voice sounded in Lin Wan's ears, very charming.

She didn't understand why the usual boring assembly instantly became easy to understand when he came out of his mouth, she felt that Cheng Yu seemed to be shining at this moment, and the aperture shook her heart for a while.

"Seriously. Cheng Yu knocked on the table and motioned to Lin Wan not to get distracted.

He pretended not to see her blushing face and continued to explain, "The mistake in this question is that you ignore the situation that a is less than 1, and when solving a quadratic inequality, you must make it a habit to consider parabolas and arguments in ......"

"In this problem, you ignore the boundary point, for the operation of the intersection, union, and complement problem with parameters, you must consider the boundary point......"

Many, many years later, Lin Wan can clearly recall the picture of that day.

In the huge lecture hall, the cold and arrogant boy sitting in the first row buried his head in telling her the math problems he was best at, his eyes were sometimes sharp and sometimes gentle.

Since then, the lecture hall on the top floor has become a tacit place for Lin Wan and Cheng Yu.

Lin Wan felt a little strange why the same question was ignorant under the teacher's explanation, but Cheng Yu was able to point out her problem and give her a clear direction.

Following this line of thought, with her already intelligent mind, the door to the magical field of mathematics was gradually opened.

Although the two tacitly do not have any communication on weekdays, there will still be people who catch a trace of unusual "adultery", and there are even "witnesses" who have seen them dating on the top floor.

Everyone recalled the previous details, and some people even thought of Cheng Yu's heroic deeds of saving the United States during military training, saying that they "secretly communicated with the song" during military training.

As a result, the scandal between the mathematical genius Cheng Yu and the nobody Lin Wan spread rapidly between those who knew and those who didn't know at an incredible speed.

The male protagonist of this topic is much more well-known than the woman, and more people are curious about who Lin Wan is.

Most of the rumors about Lin Wan are generally that this is a story of a scheming who is not tall and looks average.

A small number of people who know Lin Wan will say that Lin Wan is a low-key scholar, the first place in the English speech competition, looks like a little fairy, and looks like a handsome guy and a talented woman with Cheng Da (this should be said by Su Ziyue).

However, no matter how menacing the rumors in the secret were, the two parties were indifferent and did not even defend themselves.

Cheng Yu still has an expression of "I'm cold, who am I afraid of" every day, and a sharp look in the face of others' ridicule can make people shut up.

Lin Wan, who has always been low-key and indifferent, still came and went quietly, ignoring the pointing and whispering behind her in the classroom and outside the corridor.

Gradually, with the coming of the final exams, the two no longer "tryst" in the lecture hall, and after the relationship was completely broken, this matter was no longer talked about by so many people.

With the end of the last English exam, the first semester of the first year of high school came to an end.

After Lin Wan talked downstairs at Chen Xue's house, she was in a good mood and walked in the direction of her house humming a little song.

After all, the last subject of English is her strong point, not a full score is not much different from a full score, plus this math test, Lin Wan has never been easier.

She thought she should be in the top ten.

Lin Wan's building is the only 7-storey commercial house in the community, and the others are residential buildings with their own courtyards similar to small villas, and there is a narrow passage between this building and a small villa next to it.

As soon as Lin Wan walked downstairs, she saw a figure standing motionless in the dark hallway, looking a little crazy.

She slipped her hand behind her back and searched for the knife in her bag. Since experiencing the attack, she has become more vigilant.

Before she could touch the weapon, she saw the man walking towards her.

Through the faint moonlight, Lin Wan saw his appearance clearly, and instantly breathed a big sigh of relief.

Lin Wan was not surprised that he would know about her home, after all, he was the home he sent her back to after coming out of the drug-making den that day. But what surprised her was why he was here at this moment.

Just as she was about to ask him, a strong force pulled her into the aisle, and the voice of the neighbor kept talking behind her.

He took both of her arms and pressed her against the wall, and she was encircled in his arms, her heart pounding uncontrollably.

It was only when the neighbor's voice died down that the man slowly let go of her and turned his back against the wall.

Half a salary, he opened his mouth unhurriedly, "How did you do in the final exam this time?"

Lin Wan hadn't recovered from the wall knock just now, and after a while, he realized that he was referring to the math exam.

She said happily, "It's not bad, I handed in the test paper early for the first math exam." Thank you, Cheng Yu!"

That was the first time she called his name, and Cheng Yu, many years later, can still remember the night sky that night, even if there was not a single star, but still shining with a bright smile, and the soft voice of Wu Nong who called his name.
