Two small boys and girls, both minors.

In the first middle school of the city, under the big banyan tree, the names of the two of them are engraved.

Fang Chao, Zhang Ling.

In the name of mathematics, I swear that I wish love to hold the hand of my son and grow old with my son.

It is not a particularly heavy oath, but Fang Chao swore an oath based on his studies, which shows the importance he attaches to this feeling.

Without kissing, young love is young, as long as there is him (her) by his or her side.

"I didn't expect us to cause such a big sensation together, and the boys who pursued you almost tore me apart."

Zhang Ling smiled and asked, "Hehe, are you scared?" ”

"I was a little scared at first, but later...... You know. ”

Fang Chao replied truthfully, that group of people was in the dark, and there was actually a teacher attacking him, he was so panicked at that moment, how afraid he was beaten, after all, he pretended to be too forced, and provoked a lot of enemies in the school, who knows if he would take this opportunity to fight him.

It's just that what Fang Chao didn't expect was that the final result would actually evolve into that appearance, which made him still want to laugh now.

Zhang Ling said with a smile, "I didn't put pressure on you, I'm afraid that you won't want me because of this." ”

Fang Chao grinned, "I didn't even have to worry about the paper, let alone this...... It's just that I didn't expect you to be so talented in high jump, and other people will jump 1.6 meters in their early teens, and you will directly be 1.78 meters, which is about to break the record of 1.8 meters. ”

"Because my dad is an athlete, so I have been training with him since I was a child, others should have a childhood, but I don't, I just do my best to make myself better, if I can, I would like to be like an ordinary girl, the bed at home is full of rag dolls, have a happy childhood, and I, it's sad and tears."

"Do you regret it?"

Zhang Ling shook her head, "I had the idea of giving up, but I didn't regret it, if I wasn't excellent, how could I meet you, at least I'm not so good, I'm afraid I don't even have the qualifications to enter your world, so I will work harder to make myself better." ”

"Actually, it's not the same thing, I'm not with you all because you have developed motor nerves, it's not because you're good-looking, it's just because every time I'm with you, I can always find some inspiration, so ......"

"Ah...... So what inspiration are you with me for? ”

Zhang Ling suddenly became a little lost.

"Huh?"

Fang Chao was stunned for a moment, not understanding why Zhang Ling was depressed, but he immediately said, "I don't know how to say it, it's just that I'm very happy when I'm with you, sometimes I miss you when I don't see you, I see you have such good results in high jump, others cheer for you, I will also be happy from the bottom of my heart, I think, it shouldn't be because I can find inspiration in you, right?" ”

Zhang Ling sneered, looking at Fang Chao's deflated appearance, she was in a good mood, the all-round student kept showing stupidity on her body, how could she not make Zhang Ling feel happy? It is said that the IQ of a boy who falls in love is zero, so at first glance, it seems to be really the same thing.

And suddenly, Zhang Ling seemed to have thought of something, and her face suddenly turned red.

Fang Chao couldn't help but be a little curious, "What's wrong?" Do you have a fever? All of a sudden, your face is so red? ”

Zhang Ling said, "You're complaining." ”

When Fang Chao put his hand on Zhang Ling's forehead, Zhang Ling realized that he wanted to be crooked, and his face couldn't help but become more ruddy, doesn't he usually drive with his boyfriend? I'm so distressed, he seems to know a lot, he won't dislike himself, right?

But soon Zhang Ling asked, "By the way, I want to ask you something." ”

Anyway, I've become my boyfriend, and there's nothing I can't say about topics that shouldn't be asked, after all, I still have to ......

"What's the matter, you say."

"The last time you were in the cinema, you stared at my ......"

"What are you staring at?"

Fang Chao was stunned.

When Zhang Ling heard this, she beat Fang Chao's chest hatefully, "What do you say?" ”

Fang Chao suddenly realized, first stared at Zhang Ling's chest, and then quickly entered his own rhythm, when it came to the professional field, Fang Chao's eyes were full of excitement, "You said this, didn't we watch a movie together at that time, and then a question naturally popped up in my mind, and as a result, this question bothered me for a long time......"

"What's the problem?"

Zhang Ling couldn't help but be a little curious.

"Ideas for Solving the Problem of Function Definition Domains."

"What does this have to do with me? You...... And then you just ran away all of a sudden? ”

"Of course it has something to do with you, I didn't think of a good entry point for this idea at all, and even if I really want to solve it, it will inevitably be a huge project, and then you gave me inspiration, and I looked at you...... That ups and downs...... Well, it's a smooth feeling...... So I thought about why I had to solve the whole function process, and whether it would be easier if I just did the band analysis, so along the lines of thought, I solved the problem of this function, and named this type of function definition domain problem the band function......"

When Zhang Ling listened to Fang Chao say these words, when she was 'up and down' and 'smooth', her face turned red, it turned out that he was staring at herself, but she was thinking about this aspect of things...... And when Fang Chaoyue became more and more excited, all that popped up in Zhang Ling's mind was punctuation: ????

"Although I got the band function done, I encountered some problems later, I was good at math problems, but I couldn't get the upper hand in the language expression, in order to write the band function into a paper and publish it in the math journal, it took me a long time to get it done...... I'd rather face more math problems than waste too much time on this, but this is the way I have to go, and it will take a little while to wait for a reply from the Annals of Mathematics. ”

When Fang Chao thought of the few days when he wrote his paper, he still remembered it vividly, it was an unbearable past.

"You're going to publish a book?"

Zhang Ling was a little surprised, is her boyfriend so good that he is? is only a sophomore in high school, and already has the ability to publish books.

Fang Chao said helplessly and bitterly, "Others make money by publishing books, and I have to spend my own money to publish books, and if I pass the review, I will also spend money to pay the page fee." ”
