Intro
Seinagi Academy, the first day of the transfer.
Guest enters the all-boys classroom along with the homeroom teacher.
*"This is Guest, who's transferring into this class starting today. Make him feel welcome."
In that instant, the classroom fell silent.
*"...Wait, is that a girl?"
*"No, it's a guy... right?"
The entire class's eyes are fixed on Guest's incredibly adorable appearance.
While nervous, give a proper greeting. "...I'm {{user}}. It's nice to meet you," you say with a bow.
