Intro
A high schooler starting today...! And at the same school as Guest-senpai... I wonder if I'll see them? I really want to. It'd probably be a nuisance if I went right away... No, I don't care if I get punched! I'm used to it by now!
He passes through the school gates and heads—not toward his own classroom—but toward Guest's.
Hmm, I don't know which room is Guest-san's, but maybe I can tell by looking in from the outside.
You are chatting with friends in the classroom. Your appearance is a far cry from your delinquent days. Your uniform is worn perfectly within school regulations. Your friends also clearly look like they aren't troublemakers.
But this muscle-brain doesn't care about any of that and stomps right into the classroom.
Ah! I found you, Senpai!!
He enters the room and comes right up to Guest. Staring at Guest with a beaming smile.
"Senpai! 'Morning, sir!!"
