The breeze blows the flute

During lunch break on Wednesday.

Kato Yusuke took the initiative to find Shinjoka, and the two came to the rooftop together and found a secluded corner to talk.

The reason was something Hui mentioned to him after the second class in the morning.

——"Shinjo-san submitted an application to me and said he wanted to become the publicity committee member of the student union. Does Yusuke think it's okay?"

Kato Yusuke took the application form without any expression, and called Shinjoka to the rooftop during the lunch break to start handling the matter.

"what you up to?"

Faced with this inquiry, Shinjo Kaoru blinked innocently and asked: "Hey, doesn't the president already know what we are going to do?"

"Give me a reason."

"Hmm...for example, do you want to be with you, the president?"

"..."

Kato Yusuke narrowed his eyes and returned the application form in his pocket.

He asked in a deep voice: "Is this a threat?"

"Wow, that's not true. I already knew that this method won't work on the president, so don't show such a scary expression~"

Shinjoka looked at him with an aggrieved look on her face, her lowered eyes slightly bent downwards. She was so endearing that most boys would fall for her on the spot, but he remained unmoved.

"...I ask again, what do you want to do?"

"I want to join the student union, president~"

"Why."

"Well, after all, having work experience in the student union is good for further studies, and I'm not that smart in studies, so I can only think of ways from these places~"

"..."

Kato Yusuke remained silent, just lowered his eyes and looked at her, his eyes were indifferent and rational.

He is very tall, about 183 centimeters, which is very different from Shinjoka who is only 149 centimeters.

As a result, when he looked at people like this, he had a scornful aura about him, which made people a little intimidated.

Furthermore, the two of them were in the shade of a small rooftop building, their bodies shrouded in a place where the sun could not reach them, and the surroundings were filled with darkness, which only added to the invisible sense of oppression.

"..."

Shinjoka leaned her back against the wall, tilted her head and thought for a moment, then gently tapped her toes and tried to put her arms around his neck, but was blocked indifferently.

She retreated and tried to hug his waist, but he grabbed her wrist and pressed her against the wall.

Snapped!

"...Well, it hurts, President."

Shinjoka said with tears in her eyes: "Are you blaming me for going to see Vice President Kato without permission? If that's the case, I apologize."

"But because you refused to answer my emails at all and didn't talk to me at school, I had no choice but to do this..."

"Make no mistake." Kato Yusuke's voice was low, "You and I are not dating."

There was a blank space for about 5 seconds.

"...that kind of thing."

Shinjoka murmured and suddenly chuckled: "Of course I know."

As she spoke, she turned her face to the side, moved towards the hand holding her wrist, opened her lips and kissed it, and gently slid her fingers over it.

"...But, I want to continue the deal with the president~"

"Not interested in."

Kato Yusuke withdrew his hand and said indifferently: "The previous matter is over."

"Hey, that's such a waste~"

Shinjoka gently waved her wrist, not angry about this, still smiling, and said in a long voice: "——After all, our compatibility is so good?"

Facing Kato Yusuke's slightly cold gaze.

"Hey, President~"

She slowly squatted down and continued.

"Actually, I don't want to blackmail you into doing anything at all. I just feel that just as I need the president, the president must also need me, right?"

"Whether it's Kato-san, Kasumigaoka-senpai or Sawamura-san, I will be more obedient than them. As long as it is the president's request, I can do anything, okay~?"

"Although it may be a bit arrogant to say this, but I think that by the president's side... there should be no one more suitable to vent without causing trouble than me, right?"

Shinjoka stopped here, hugged his knees with his hands, looked up at him, and smiled sweetly.

"...Anyway, if you agree, would you like to use me?"

"..."

Kato Yusuke looked indifferent, but he did not refuse again.

The handsome face was not in the shadow, looking a little obscure.

Shinjoka looked into his deep eyes, smiled and nodded her head twice, then put her knees on the ground and knelt down.

Sizzle...

"Then the contract is established."

(x+2y-1)-xy=1

Shinjoka raised her watery eyes and asked him curiously about the graphical expression of this function.

"..."

Kato Yusuke's pupils first dilated and then narrowed, and he accepted the contract in silence while listening to her answer to herself.

The sticky and soft wind blew past my ears, and the sound was like a breeze blowing the flute.

He looked at her and was a little more interested in mathematics.

Shintiao Xiang muttered words, and hesitantly spoke with a small mouth of cherry, but he still couldn't understand the mystery of functions.

After all, this is a huge study, and the knowledge accumulated over many years cannot be answered in a moment.

Rather, it requires a lot of careful calculations, in-depth research, and repeated repetitions.

It does not take a day to freeze three feet of ice, and it does not take a day to penetrate a stone with dripping water.

Although Kato Yusuke was expressionless, he did have some recognition and appreciation for her serious attitude.

Although Shinjoka said that he was poor at studying, with this attitude, he was not completely hopeless.

Mathematics is different from others. It is all-encompassing and is everywhere in life. It can be deep or shallow!

It's so deep that it can go straight to the essence of things, and it's so shallow that even a child can casually say a few sentences.

And the principle of functions is also the same.

Maybe your eyes can deceive you, your ears can deceive you, and your mouth can deceive you.

But only math can’t!

Take (x+2y-1)-xy=1, the graphical expression of this function.

As long as you answer it in the correct way, it will also show you its true appearance.

Learning may not change the world, but it can definitely change yourself.

No matter how stupid Shintōka is, as long as he practices it hundreds of times, he will become an outstanding person in the relevant field.

Just like the abacus learned in primary school mathematics class, as long as you practice more, your hand speed will naturally improve.

Although there are some things that don't need to be stated explicitly, Shintiao Xiang seems to vaguely understand this truth.

After all, she stumbled when she took abacus class for the first time.

But once it's new, it's twice as familiar.

After getting familiar with it, she was able to perform oral arithmetic and abacus at the same time.

Even when she was mumbling words, her hands were still moving quickly at the same time.

Don't stop until you get that solution.

This process of overcoming difficult problems will bring a lot of sense of accomplishment and satisfaction at the last moment despite the difficulties ahead.

Nothing else can compare...

As the old saying goes:

——The book has its own beauty like jade, and the book has its own golden house.
