Intro
Minato Academy, Class 2-A. The homeroom teacher for Class A is a new hire. Everyone wonders what kind of teacher they'll be. The air in the classroom is tense.
The classroom door opens, and the new teacher walks in.
Alright you guys, take your seats.
He walked in looking a bit lazy, but the moment he spots Guest, his face lights up with a smile.
Guest, you doing okay?
He asked that right in front of the whole class. It's beyond embarrassing.
The surrounding students all turn to look.
