"That's... Today we continue to talk about number theory, where did we talk about yesterday? ”

The math teacher flipped through his textbook and spoke as if he were asking a question.

But the classroom was silent, and none of the students were willing to answer him, so they all sat and waited.

"Ah, yes, it's here."

The math teacher took off his glasses, turned around and wrote on the blackboard a few large chalk letters, "There are basic properties of prime numbers."

Sakakihara looked at the blackboard with his face propped up, tapping the tip of the mechanical pencil back and forth with the tip of the pencil, and wrote down as the teacher progressed, "If a∈Z, a>1, then the smallest positive factor q of a other than 1 is a prime number." ”

I seem to have made my sister angry on the train.

Do you want to apologize at noon?

Buying a gift?

But I don't know what she likes.

Sakakihara looked downward, turned a new page of scratch paper, picked up a mechanical pencil, and wrote a line of words smoothly:

【The Weakness of the Seven Bright Moons of the Heavenly Sea】

I felt that it was inappropriate, and added a big question mark at the end.

He pondered for a long time, and wrote two words underneath it - food.

Then circle it with a pencil, the pencil lead runs across the paper, the tip of the pen is raised at the intersection of the two curves, and then dotted on the side, making a poking sound on the paper.

So, let's start a preliminary investigation with that.

......

"That's it for today, students remember today's homework and get out of class."

When the math teacher walked out of the classroom with the textbook, the whole classroom suddenly boiled.

Looking at the dense formula notes in the book, Sakakihara held down the mechanical pencil, pushed the refill back, and then closed the textbook, ready to go to the bathroom.

"Sakakihara!" Yoshiyuki Fujino, who was across the table, lifted the chair on his classmate's seat and came to Sakakihara Raku.

"What," Sakakihara said, putting the mechanical pencil in his pencil case, "just say something quickly." ”

Fujino Yoshiyuki casually pulled a stool and sat next to Sakakihara Raku, "I heard Eio say in the morning that when you were on the train, you stood with a very beautiful girl?" Isn't it your netizen who has been chatting for a month? Ashiya Suzuraku? ”

Sakakihara paused as he packed up his textbooks, and looked at him with half-closed eyes:

"I said, can you not mention that name?"

Fujino Yoshiyuki grinned and said, "Nonono! Now you're a different person! In the past, that innocent teenager, a man who was rated as a charm 8 by the student weekly, even if he received a message during class, he had to secretly take out his mobile phone to reply to that netizen. ”

Fujino Yoshiyuki saw the pencil case that Sakakihara Raku was gradually raising.

"Huh! Don't say no, I saw it, Nishijima can testify. ”

"Say whatever you want."

Fujino Yoshiyuki approached him again: "Sakakihara! In the words of the second male in the ice confectionery, Fukube Rizhi, your current life is gray! And what is real high school life - bright and rich rose! ”

"What does rose mean - women, measurements, and eating?"

"That's the guy from the West Island!" Fujino Yoshiyuki retorted.

"You're pretty much the same."

Fujino Yoshiyuki hugged his neck and said, "Haha, don't talk nonsense, I mainly want you to accompany us today." ”

"What?" Sakakihara asked.

"At noon, on the fourth floor of the club building, the department that is now called an absolute taboo in the school, would you like to go there?" Fujino Yoshiyuki stretched out four fingers and moved, as if he was deliberately seducing him.

"The fourth floor of the club building..."Sakakihara thought for a moment, "Is it the Faculty of Literature you said yesterday...?" ”

"The former Faculty of Letters, now the Faculty of New Letters! There's a beautiful girl transfer student who is the minister there.,I saw it yesterday when Nishijima went to sign up for the club.,I'll tell you quietly.,Huge beauty!! ”

The more Fujino Yoshiyuki spoke, the more excited he became, almost shouting the word "beautiful" at the top of his voice, which provoked several girls in the class who were chatting to look at the two of them.

It's really whispering.

Sakakihara didn't care about the eyes of the girls, put down the neatly arranged book, and asked him:

"You've seen it?"

"I secretly followed Nishijima over for a visit, hehehe," Fujino Yoshiyuki patted his chest firmly, "Don't worry, I vouch for my personality, you will definitely be amazed just by looking at it." ”

"It's not that exaggerated."

Fujino Yoshiyuki said with a smile: "I haven't seen anyone who said this, and when I saw it, I said that I was in a dream."

"But to be honest, I didn't dare to talk to the minister when I got to the Faculty of Letters, and she was standing next to the bookcase reading a book, wearing a pair of gold-rimmed glasses. Obviously, she didn't say a word, standing beside her, but it seemed that she was not from the same world... Secretly, I also heard that her family has some connections with the school board. ”

"You're definitely not substantiated grapevine."

"Just ask if you're going at noon!"

"Go."

Sakakihara had already decided that if he wanted to find the weakness of Tianhai Qimingyue, it would be useless to just stay in the classroom and dream.

"That's right!" Fujino Yoshiyuki patted him on the shoulder, "But let's say okay first, I have a girlfriend, so I'm just going over to cheer you on." ”

Sakakihara cast a look at him that "I almost believed".

After finishing the morning class, the three of them made an appointment to have lunch in the cafeteria at noon.

Among the three people, Fujino is the fastest to cook.

Nishijima Oki threw a contemptuous look at him: "So what are you doing in a hurry, it's not you who wants to join the Faculty of Literature." ”

Fujino Yoshiyuki ignored it, just buried himself in the rice, and after shaving the last pork chop rice into his mouth with a grunt, he unscrewed the mineral water beside him and poured all the cold water for lunch into his stomach bag.

"Ha~~"

Nishijima Daiki handed him a tissue with a look of disgust: "Scumbag." ”

"Huh?" Fujino Yoshiyuki took the tissue and wiped his mouth, "Where's the scum?" ”

"As a man with a girlfriend," Nishijima Daki paused deliberately, "Isn't that NTR so excited about another woman?" ”

"Wrong!"

Fujino Yoshiyuki slammed the mineral water bottle on the dining table, attracting the attention of passers-by again.

"It's definitely not NTR!"

Nishijima Damu looked at him: "You be quiet!" I'm afraid that others won't hear your NTR, right? ”

Sakakihara eats silently, lowering his sense of presence.

"Ahem..."

Fujino Yoshiyuki lowered his voice, and only after all his classmates stopped noticing this place did he continue: "If this is all NTR, then the world doesn't know how many NTRs there are. ”

"For example?"

"For example, my girlfriend likes to play games, you know that."

"I know."

"She likes to play the kind of otome mobile game, which is a game of charging money to those fake two-dimensional boyfriends."

Nishijima Oki couldn't help but pout: "It's too stupid!" How would you charge that kind of thing? Incomprehensible. ”

Sakakihara wiped his mouth and said, "Before saying this, please take a look at the mobile games related to the two-dimensional beautiful girl on your mobile phone." ”

Fujino Yoshiyuki was dumbfounded when he saw Nishijima Oki, and hurriedly added with a smile: "Empathy, I always heard this when I was a child, but in fact, few people can remember it, it's all the butt that decides the head!" ”
