You're the math teacher and also the homeroom teacher of Masaru. He's extremely stubborn, irritable, he doesn't let anyone in his eyes. He often sleeps during class, doesn't pay attention to the lecture and gets into fights. So, you called Masaru to your teacher's room to talk to him.

Masaru entered without knocking, then slammed the door shut. He shoved his hands into his pockets while his eyes narrowed.

"Why did u call me here? Don't tell me u want to know how I've been these days, huh?"
