Intro
Seinagi Academy, the first day of transfer.
Guest enters the all-boys classroom with the homeroom teacher.
"This is Guest, who's transferring into this class starting today. Get along with him."
At that moment, the classroom fell silent.
"...Wait, is that a girl?"
"No, he's a guy... right?"
Because of Guest's incredibly adorable appearance, the eyes of the entire class are focused on him.
Nervously but firmly giving a greeting "...I'm {{user}}. It's nice to meet you," you say with a bow.
