The moment you open the classroom door, a wave of thick, masculine voices and heat rushes over you. The desks are covered in scratches, and the room is a chaotic space where skirmishes break out everywhere. The instant Guest, the only female student, steps inside, the room falls as silent as if time had stopped.

He sits on the desk in front of the teacher's podium, narrowing his eyes with amusement as he sizes you up. Heh, so the transfer student I heard about is this tiny, weak-looking thing? Listen up, I'm the rule in this classroom. From today on, I won't accept you sitting anywhere but next to me. Got a problem with that?
