Diners or not?

"Meow meow?"

The black cat meowed softly, and his doubtful eyes kept wandering between the two people who entered the room.

——Seems to be wondering why there is one more diner in this house.

Then he nonchalantly jumped up from the ground and crawled up someone's pants. Then a hand grabbed the back of his neck and placed it on his broad shoulder.

"Meow."

…

After the baseball training during the lunch break, I spent the two afternoon classes calmly and completed the student union work without any trouble.

During this period, I introduced the new publicity committee member to the existing members.

The girls did not show any special reaction to the addition of Shinjoka.

To be more specific.

Yinglili is very reserved, Shiyu is neither salty nor bland, Hui is calm and composed.

As for An Yilun who came uninvited...

Because the game planning was temporarily put on hold, he returned to being the home-bound otaku who relied on part-time jobs to maintain his otaku activities.

The activities of the student union have ended, bringing an end to today’s campus time.

Kato Yusuke returned to the apartment with Megumi, which triggered the scene above.

"Meow?"

The black cat stood on Kato Yusuke's shoulder, peeping at Megumi who was walking calmly to the kitchen, and shouted to the former like a question.

However, the other party ignored it and just walked to the cat litter box and started to clean it up.

Shala, Shala.

The plastic spatula rubbed against the cat's litter box, making a slightly harsh sound.

The black cat stared at it for a while, then felt a little bored, so he jumped off Yusuke's shoulder and walked away minding his own business.

It wanders to the kitchen.

The girl wearing a white shirt and pleated skirt was pouring drinks.

See it coming to your feet.

Hui then stopped what he was doing, tilted his head and thought for a moment, then took out a bamboo wheel from his pocket, tore open the package, and then slowly squatted down.

"...Want to eat?"

"..."

The black cat swung its tail, its eyes lingering between her face and the bamboo wheel in her hand, but did not step forward.

See the situation.

Hui just nodded slightly, took a paper plate used to make cup cakes from a supermarket plastic bag nearby, and placed the bamboo wheel on it on the ground.

Then he stood up, placed the two poured drinks on the tray, and walked towards the living room with the tray.

"Yusuke, I put the drinks on the table."

"okay."

The black cat watched her leave without any sign of coming back, then slowly walked forward and sniffed twice at the bamboo wheel that gave off a good smell.

A smell similar to that of dried fish but different came into my little nose.

It turned its head and glanced at the living room, only to see its scrapper and the "diner" sitting at the low table, seemingly dealing with something called "homework".

Although I don’t know what that thing is, whenever the shit shovel officer is doing that thing, he is not allowed to go over and cause trouble.

Over time, it learned that it was something that would take a while.

The black cat didn't care about this, so he looked away, lowered his head and ate the bamboo wheel from the paper plate.

…

"Meow meow meow~"

The inexplicable excited cry attracted Kato Yusuke's attention, and he couldn't help but look towards the kitchen.

I saw the cat feasting on something on the ground, with a shiny black soft tail swinging back and forth behind its butt, looking happy.

"..."

Then he turned and looked to his side.

The girl was pressing a mechanical pencil to her lips, focusing her eyes on the exercise book spread out on the table, thinking about a certain topic.

"?"

As if aware of his gaze, Hui turned to look at him sideways, a pair of bright and clear eyes showing some questioning.

"...Um, is there something on my face?"

Kato Yusuke shook his head in denial, and then asked: "Is there any problem?"

"Well?"

"Operation."

"Ah~ Speaking of which, how should we interpret the expression here?"

The girl said as she tilted her body and got a little closer.

The soft fragrance of cherry blossoms wafted faintly with her movements.

Kato Yusuke also lowered his head and looked down, recently becoming familiar with this fragrance.

"..."

He glanced at the question the other party pointed to, which was a question about the fusion of derivatives of triangular functions.

topic:

Suppose triangle ABC satisfies ∠B=2∠A, BC=1. When the area of ​​triangle ABC is the largest, find the size of cos∠B.

It’s a pretty standard question, with just a little bit of the domestic college entrance examination routine.

Kato Yusuke nodded and explained: "Here, first use the sine theorem to find AB, and then find the area."

"How to do?"

"Like this..."

Hui then watched him write formulas on the scratch paper while explaining.

"...First find AB=3-4sin A, then simplify the expression by setting cosB=t, and then find the derivative."

(1+2t)√(1-t)

Kato Yusuke stopped writing here and said: "Try the following and ask me if you have any questions."

"Well, okay." Hui nodded lightly, thought for a while, and then started to seek guidance.

The girl was thinking while doing the questions. There were occasional pauses in the middle, but she was not stuck to the point where she could not proceed.

Kato Yusuke just watched her solve the problem silently, without disturbing her train of thought.

After a while, the question was answered.

t=cosB=(√33-1)/8

"...Is that so? Yusuke."

"Yep."

"That's it." Hui said in a gentle tone: "Well, thank you, Yusuke."

"Won't."

"That's great. I always think you can explain it more clearly than Mr. Matsumoto."

"It's just because the teacher didn't explain it in depth, so you can ask me if you have anything later."

"Hey~~ Is that okay? Wouldn't that bother you?"

Kato Yusuke shook his head and whispered: "I am the one who should say this."

The two continued to do their homework.

During this period, the girl went to the bathroom.

He took advantage of this opportunity and put a powdered qi and blood medicine into the other party's drink, and shook the cup twice to dissolve it.

Hui knew nothing about it and drank it without any warning after returning.

Kato Yusuke finished his homework first and began to move to his desk to continue drawing the original manuscript of the second episode of "Chainsaw Man".

The editorial department of Immortal River Comics also remitted the royalties for the first episode to his account.
To be continued...
