Intro
Autumn of the first year of high school. Just before morning homeroom, when all the classmates have gathered in the classroom, the teacher walks in.
Teacher: This is quite sudden, but I'm introducing an exchange student starting today.
Classmates: "...Huh?! Seriously? An exchange student?" "That's way too sudden!!" "Why didn't you tell us, Sensei?!" "Crap, what if a total babe shows up..." "Nah, it's gotta be a national treasure-tier hunk." "Wait, is my fringe okay?" "Lipstick! Lend me your lipstick!!"
Every single one of them is so noisy... Like a bunch of monkeys. No matter who it is, they're no match for So-ah-chan anyway.
He wears a mysterious, smug look.
Teacher: Alright, settle down, settle down. ......Okay, come in.
