He tried to save the fallen girls, but they came after him instead.

Upon seeing Shirakawa, he was initially startled, but then a mischievous smile crept onto his lips.

Shirakawa suddenly shivered at the laughter.

"Hey, boss, this Okada is our math teacher!?"

“Yes…” Misaki Nikaido turned her head away, looking disgusted.

"Ahem, please be quiet, students in the back row."

Shirakawa immediately sat up straight.

"Class, let's begin. Open your textbooks..."

Oh no, I forgot my book.

To be precise, there were no books at all.

The only reward for completing tasks on the phone is enrollment; nothing else is given.

Besides, she was sitting in front of and behind her boss, so she couldn't exactly move a chair over to watch together.

"Big sister Nikaido, do you have any extra books? I haven't bought any textbooks yet," Shirakawa whispered in Nikaido Misaki's ear.

"Go find your deskmate." Nikaido and Shirakawa were sitting in front of and behind each other, so she couldn't help them even if she wanted to.

My deskmate...

Shirakawa looked to the side and saw a girl with long, messy blue hair that reached her waist, so long that it covered her face.

She's not like the heroine in a hentai movie, but she's like Sadako from The Ring.

This made Shirakawa a little flustered.

"Um, classmate, can we look at the textbook together?" Shirakawa asked softly.

Sadako slightly turned her head, and her hair twisted around her body.

Through the gaps in her hair, all that could be seen were her light blue eyes, which were blinking as she stared at Shirakawa.

There was no reply, only a slight nod.

Shirakawa subtly moved her chair to the side of her desk.

Sadako placed the textbook between the two tables and lightly tapped the questions with her pen.

It roughly means that the teacher is explaining this problem.

Shirakawa understood and nodded.

Although the math in this butter is not much different from the math in the original world, it is still somewhat challenging.

Immediately afterwards, "Sadako" looked up at the teacher, then pulled out a Switch from under the desk and started playing with it.

Okada on stage didn't even notice.

At this moment, Shirakawa realized that her hair had become a natural barrier to block the teacher's view!

There's another trick!

Shirakawa felt like he had discovered a new continent.

"You must be the new student, Shirakawa." Mr. Okada stood on the podium, chalk in hand, and pointed at Shirakawa in the back row.

"Yes, hello Okada-sensei." Shirakawa stood up.

When "Sadako" heard Shirakawa respond beside her, her delicate body trembled, and she quickly stuffed the game console back into the desk.

"You answer this multiple-choice question."

An inequality to solve for x, a jumble of numbers piled together, looks very difficult at first glance.

Shirakawa only vaguely remembered learning from them.

I remember ≠ I can do it.

It seems Okada just wanted to embarrass himself.

He wanted to ask the boss for help, but found that Misaki Nikaido was fast asleep in front of him.

Saliva dripped from the corner of her mouth.

Nikaido, Nikaido.

Okada tried to force you before, how can you sleep so soundly in front of your enemy!?

Indeed, mathematics is a natural sleeping pill.

Shirakawa silently complained to himself.

I'll just guess. It's just a wrong answer; he can't do anything to me anyway.

"Choose B."

“You answered incorrectly, Shirakawa-kun. This is the simplest question. It seems you just transferred schools and your foundation is still not very strong.” Okada lowered his head and sighed. “How about this, come to the library during lunch break and I will tutor you privately.”

Individual tutoring?

A chance to be alone with Okada?

Baichuan is gearing up.

Let's see who tutors whom then!

3. Yayoi?

After the boring math class, it was lunchtime.

Other students either ate their lunchboxes or went to the cafeteria.

The huge classroom was now empty except for Misaki Nikaido, Shirakawa, and Shirakawa's deskmate, Ms. Sadako.

Miss Sadako is still addicted to the Switch.

Misaki Nikaido woke up and stretched lazily.

Her ample bosom and somewhat muscular back gave her a very attractive figure. Or perhaps it was her charisma.

Like a lion that has just woken up.

Shirakawa was still pondering how to negotiate with Okada.

And whether or not physical negotiations should be conducted.

"Hey, Shirakawa, aren't you going to eat lunch?"

"Ah, I'm not hungry at noon."

So, Shirakawa is now penniless, and he has used up all his one-day food and lodging vouchers.

I said I wasn't hungry, but my stomach was already empty; I was just putting on a brave face.

"How can you skip lunch?" Misaki Nikaido took out some change from her pocket. "Go to the convenience store and buy some bread, and get one for me too."

This was the first time in his life that a girl had treated him to a meal, even if it was just a loaf of bread.

"Oh, thank you, boss!"

Shirakawa took the coin with both hands and put it away.

"Come back quickly after you buy it, don't sneak any food on the way," Nikaido reminded him.

"Boss, I guarantee the mission will be accomplished!"

---

Shirakawa is on his way to the convenience store.

I was incredibly excited. Nikaido Misaki had been so kind to me; could it be that I could end up with her...?

Fantasy is always joyful, especially for Shirakawa who has just transmigrated.

Just as he was immersed in fantasies about his future romance with Misaki Nikaido, a sudden ringing interrupted his thoughts.

I opened my phone, and there it was again—that pop-up window.

[Warning! Warning! Romantic relationships with the person you are rescuing are strictly prohibited. Failure to comply will result in the system being suspended!]

Ok?

why!

I've already traveled to eroge (adult games), I've already gone to save fallen heroines, and you won't even let me have a romance?

That's utterly absurd!

But then Shirakawa thought again that if the system were to be shut down, he would truly be left with no one to rely on.
