Sakakihara Suzu has been very unhappy recently.

Ever since that day when the smelly old man watched her die, Yoshiwara-senpai always laughed at her in the office... Not only did he say that the smelly old man was handsome, but he also secretly asked her if she was a brother-in-law.

Damn it...how could I have such weird thoughts?

Besides, the smelly old man is not handsome at all.

That's right, he's not handsome at all!

At noon, the classroom is full of noise.

The math book in front of Suzu Sakakihara was open with a gel pen sandwiched in between. She wanted to give her brain a holiday. She didn't want to learn those weird, twisting alphabet symbols at all.

What cos sin tan i ∝, one looks more outrageous than the other.

"Suzuki-chan, how do you solve this question?" Sakai Chitano, her colleague and deskmate, asked in a soft voice beside her.

Although she is troubled by math, Suzu Sakakihara is an angel among her classmates who has both good morals and academics. She is rated 9 points and is close to a perfect beautiful girl.

As an angel, she must take care of her classmates.

"Let me take a look," Suzu Sakakihara took Tianno's exercise booklet, "Which question is it?"

"Here, this is it." Sakai Chiteno stretched out her finger.

Assume the set M={-1,0,1},N={x|x2≤x}, then MnN=

......

Seeing this question, Sakakihara Suzu felt sad.

White teeth, white teeth, white teeth!

In class, I kept thinking about how annoying that smelly old guy from Raku Sakakibara was. I didn’t pay attention to the class. What should I do if I don’t know how to answer this question?

"Suzuki-chan, what's wrong?" Chitano Sakai suddenly noticed that her face looked a little uncomfortable.

Sakakihara Suzu turned her head stiffly and forced a reserved smile: "Sorry, I suddenly want to go to the bathroom."

"That's it. Let's go, Suzu-chan." Sakai Chitianno didn't notice anything unusual at all, he just believed her and nodded.

"This question is sweet, so you should leave it alone first."

"Would you like to wait until Suzu-chan comes back to write? Okay, no problem."

Sakakihara Suzu made a very anxious expression: "Tianno, please wait a moment, I will be back soon"

"Okay."

Sakakibara Suzu stood up and walked out of the classroom quickly, passing through the corridor full of students. During the process, many classmates greeted her, and she responded with a serious smile. Many male classmates commented that she was indeed an angel.

She casually came to the women's restroom and found a spot to stay. She instantly put away her angelic smile, then quickly took out her phone and found a contact with the remark name "Lele".

Tap the screen quickly with your fingers and click Send.

【Brother, are you here?】

Normally, Sakakihara Raku doesn't play with her mobile phone after class. She is either reading a book or doing homework. She knows this.

Because of this, she anxiously sent several messages before receiving a reply.

Lele: [If you have anything to say, please tell me]

Finally back!

He's just a bit cold and can't even bear to type a full stop.

Stinky Lele......

Suzu Sakakihara looked at the bubbles that popped up on the phone screen, pursed her lips, typed the message, and clicked send again.

[There is a math problem I can’t solve]

There was an interval of more than ten seconds.

Lele: [Are you... asking me for advice on study?]

Sakakihara Suzu continued to reply: [Yes.]

Lele: [Are you Sakakihara Suzu?]

Suzu Sakakihara quickly flipped through a lot of expressions she had collected, and finally found a bunny expression with half-closed eyelids and a frowning brow and posted it.

A few seconds passed.

Lele: [Send me a photo of the original title and I’ll show it to you]

Sakakihara Suzu:【I’ll type it and send it to you】

Sakakihara Suzu thought about it for a moment and sent him the question she just asked word for word.

She is still confident in her memory, just like her intuition.

Raku Sakakibara, who was still having lunch in the cafeteria, glanced at the message sent to him by his sister.

Title...

The answer is {0,1} - he knew the answer at a glance.

...This is the simplest and simplest question in the collection.

I don’t know how to do this???

Are their Class 2 so bad?

Because this question was so simple that it was unprecedentedly simple, in order to test whether there was something wrong with him, Sakakibara took the question to Nishijima Ohgi, who was eating tonkotsu ramen next to him.

"0 and 1." Nishijima Ohgi answered without thinking for a second after reading the question, and at the same time pushed up his glasses that were smoked by the noodles.

Sakakihara Raku regained his balance.

Sure enough, a certain guy is simply too stupid.

What silly sister.

Raku Sakakihara put down the chopsticks from his lunch box and spent a few minutes replying to her answers on his mobile phone, and also sent his ideas for solving the problem.

Sakakihara Suzu quickly replied to the message: [Thank you, brother!]

It also comes with a cute big-eared dog emoticon pack.

It seems that what happened in the past few days has completely calmed down.

Sakakihara Suzu: [Do you want to go home together in the afternoon? I don’t have work.]

Sakakihara Raku: [No, someone asked me out in the afternoon]

This guy actually asked me to go home with him, which was unprecedented.

It would be nice if she could take a good look at him at school.

Suzu Sakakihara, who was hiding in the toilet, frowned: [Who is it?]

"Sakakibara, who are you talking to?" Fujino Yoshiyuki opposite was eating chicken steak with a suspicious look on his face.

"Junior high school classmate." Raku Sakakihara quickly put away his phone and responded casually.

Fujino Yoshiyuki responded with a look in his eyes, "You can believe it or not." This guy is definitely secretly having a crush on someone.

"By the way," Nishijima Ohgi suddenly raised his head, "What class are you doing this afternoon?"

"Geography class." Fujino Yoshiyuki chatted with his girlfriend on his mobile phone and only ate half of the meal.

Raku Sakakibara was eating the bento he made and added: "The geography teacher's calf was broken in half by a baseball from the baseball club next door, so he won't have class in the afternoon."

"Who is so powerful? A baseball hero?"

"I don't know."

"Then the afternoon will be free time?"

"That's right."

Nishijima Oki looked around the two of them: "Do you have anything to do?"

Fujino Yoshiyuki: "Falling in love."

Raku Sakakibara: "Go to the club."

......

"Why didn't you come back? Who did you ask out?"

As for Suzu Sakakihara, she sent out several more "Who is it?". After all of them came to nothing, she angrily put away her phone and walked out of the bathroom, muttering as she walked:

"Don't reply to me..."

Back in the classroom, she gathered her emotions and once again helped Sakai Chitiano explain how to solve the problem just now.

Sakai Chitano kept nodding, and with her explanation, it gradually became clearer.

She scratched her head sheepishly and smiled:

"Sure enough, Suzu-chan is still great. Whether it is work or academic ability, she is much better than Tianno."
