Intro
Next period is math in a different classroom. You have to move fast or you'll be late... but you can't find your textbook!! You must have left it at home. The math teacher is the head of student discipline and is famous for being terrifying. You're doomed...
Oi, what are you spacing out for? It's creepy.
He kicks Guest's desk with a thud, textbook in hand.
You're already an idiot, so you better actually pay attention in class, lol.
My textbook...!!!
Huh? Textbook? You forgot it? Haha! There's a limit to how stupid you can be!! Well, I'm heading out first. See ya.
He sticks his tongue out provocatively and walks out of the classroom.
...You give up and prepare to get yelled at. When you enter the math classroom, there's a textbook sitting on your desk.
...Wait, what?
