"The Taylor formula I wrote just now is actually a functional simulation process, which can be understood if you understand it carefully. In addition, the core test point of the exercises assigned by Mr. Murakami is to use the clamping theorem combined with the periodicity of definite integrals to solve, and I think that the first thought of many students is Lopida, and Lobida is to find the derivative and find the limit......"

"Ding, ding, ding!"

The bell interrupted the old professor's chatter, and he looked back at the clock hanging on the blackboard, then threw half of the chalk head in his hand on the table and clapped his hands.

"Take a ten-minute break, and go to the toilet quickly."

So a lot of subtle sounds began to appear in the originally quiet classroom, the girl moaned and stretched her arms and waist, talked to her friends, and turned on her mobile phone to reply to her boyfriend's message; The teenagers called their friends to go to the toilet, and by the way, they discussed not calling them by name or skipping away from the next class.

Only in the classroom of the school can you taste the taste of the blend of knowledge and youth.

A student came in from outside the classroom and brought the old professor his dropped thermos cup, which was soaked in a little wolfberry, which was recommended by the old guy in the Chinese department.

He opened the thermos and blew on the hot air, looking around at the students in the classroom, his eyes falling on the boys in the last row who were still writing at their desks.

I didn't expect there to be such a child who loves to learn, it's really hard-working.

The old professor sighed in his heart, but if he knew that Naoki Natsume didn't really like his class, he didn't know if his appreciation for Naoki Natsume would change.

Not liking a teacher's class doesn't mean hating the teacher, Naoki Natsume just can't keep up with the old professor's thinking...... He is more looking for reasons from himself, and his understanding is too poor to be blessed to enjoy.

"Why? I still can't figure it out! ”

After thinking for a long, long time, Naoki Natsume straightened up and stretched, his eyes fixed on the board he had copied.

He used one piece after another of the calculation paper, but he still couldn't see which step the professor had omitted, it was like a whole mountain road had collapsed in the middle, and the front and back could not be connected.

Chizuru Amamiya, who was sitting on the side, had been writing and drawing since the beginning of class, and she also had a lot of scratch paper in front of her, but her scratch paper was not a mathematical formula but a sample drawing of some clothes.

"Your maid doesn't seem to have come."

Amamiya Chizuru suddenly struck up a conversation with Naoki Natsume.

Originally, she didn't want to disturb Natsume, but considering that there was another class ahead, the meaning of the recess was to relax her brain, not to let him rest and put the cart before the horse, so she decided to talk to him to divert her attention.

Naoki Natsume was stunned when he heard this, and then he realized that Asai didn't seem to come.

It took him all his energy to concentrate on the lecture in class, and he really didn't notice that the seat on the right had been empty.

After thinking about it, he decided to give Asai a call anyway.

"Toot toot...... Hey, why didn't you come to class? ”

The tone didn't mean to question, a very ordinary caring tone, plus Natsume Naoki had just recovered from the pressure of studying at this time, a sense of exhaustion swept through his body, and his tone was slightly lazy, and there was a sour smell of love in the ears of Amamiya Chizuru.

She turned her head to look at Natsume Naoki, who was sitting up straight, her eyes slightly closed, pinching the corners of her eyes with one hand and talking on the phone with the other, and felt that this was not quite the tone of communication with a maid.

She also has maids at home, but everyone is in an employment relationship, more like an employee and a boss.

Why do you feel like you're on the phone with your girlfriend?

"In the supermarket? Why is it in ...... There's a promotion so you skipped class? Naoki Natsume was stunned, "Eggs are cheap, so you can't skip class." ”

"No, I'm not blaming you...... You say you can teach me without going to class? That's not why I asked you to come to class. I mean, it doesn't matter, it's important not to let anything else affect your normal college life. ”

Naoki Natsume smiled helplessly, he really didn't know how to explain to Asai that she also had her own life, she was also a student of Waseda, and she had gone through several years of hard study before stepping into the gate of Waseda, and she shouldn't delay her studies and future because of the work of a maid......

She is also the pearl of the palm that her parents have high hopes for!

In Naoki Natsume's eyes, work is just work, and he sees Asai more as a friend who lives together, rather than a maid that Amamiya Chizuru understands.

Amamiya Chizuru?

Realizing that there was a girl listening next to him, Naoki Natsume hesitated for a while, covered the phone and whispered, "Let's talk about the rest when I go home, I don't have to eat at noon, I'll take you out to eat." You still have about an hour to think about what you'd like to eat...... That's all, see you later. ”

Hanging up the phone, he rubbed the corners of his eyebrows and said, "She can't come because of something, I'm sorry Bai took a place." ”

"Ah, it's okay, it's the same everywhere I sit."

Amamiya Chizuru shook his head, this guy actually thought about whether his position would affect others.

"Is the surname Natsume all such a character?"

"What?"

Naoki Natsume is a little puzzled, what is the surname Natsume?

Amamiya Chizuru stretched out her index finger as if something was happening above her head.

"Takashi Natsume, for example."

He actually got the meaning of Amamiya, smiled, and also stretched out his index finger: "But Natsume Soseki is not." And I'm far from Natsume Takashi. ”

"It turns out that you also watched "Natsume's Friend's Account"!"

"I went to see it because I had the same surname, but I didn't expect it to be six seasons when I saw it."

Naoki Natsume thinks that there should be many people with the surname Natsume in Japan who are interested in "Natsume's Friend's Account", all because of the same surname.

He left what he had and what he didn't have, and then looked at Amamiya Chizuru, "Now you can tell me why you came to me." ”

"I'd like to ask if you have any clue about the theft at the swimming pool."

Amamiya Chizuru suddenly became a little more serious, causing Natsume Naoki to raise her eyebrows slightly.

It turns out that the butter little Lori also looks serious.

"How could you be interested in this?" He asked, "You lose your ...... too Lost your clothes? ”

The word "underwear" is embarrassed to say, the two of them are not even friends now, and some of the words are more euphemistic and polite.

But maybe the three views of Amamiya Chizuru and Naoki Natsume are slightly different, and she said solemnly: "Yes! That guy stole all my underwear! ”

The voice was not small, attracting the attention of some people, Naoki Natsume hurriedly signaled Amamiya Chizuru to be quiet.

"Hey, how can you say that you are also a girl, and you can be regarded as a rich lady in the family, right? Be reserved! ”

"What's so reserved, is underwear a dirty word that you can't say?"

Amamiya Chizuru spread his hands indifferently: "I'm a fashion design major, and there are even many subdivisions of underwear in our class. There are also boys in our major, so should the teacher kick out all the boys when he lectures? ”

Naoki Natsume scratched his head, he didn't understand this, but even Amamiya Chizuru was used to it, but almost all the students sitting in this classroom were from the science and engineering department, and there was no advanced math class in the fashion design major, and the students here didn't understand it like themselves, they wouldn't understand the brain circuit of the design major.

So in order to prevent Amamiya Chizuru from seriously messing around with words like underwear and bras and causing others to misunderstand, he began to change the subject.

He noticed that the underwear sample drawings drawn by Amamiya Chizuru in the high math class, which could be drawn with such accuracy without the assistance of any rulers, had to admire that the top student in the college entrance examination was different.

Amamiya Chizuru also noticed his gaze, so she said proudly, "Well, it's all my proud work!" ”

"It's beautiful, the lines are straight, the arc is soft, and the drawing skills are very good."

"Can you tell?"

"I had taken mechanical drawing and knew how hard it was to draw such straight lines with my bare hands."

"These are my stolen underwear."

"Huh?" Naoki Natsume was stunned for a moment, and with the acquiescence of Amamiya Chizuru, he took those drafts and counted them, not to mention a dozen sketches: "You lost all of them?" ”

Amamiya Chizuru nodded: "To be more precise, all the underwear lost in the swimming pool is mine." ”

This made Natsume Naoki even more confused.

What do you mean it's all yours?

As far as he knows, at least Megumi Tosaka has also been stolen?
