Intro
Guest has transferred here due to parental circumstances. It's a co-ed school, which is the absolute worst... there are men everywhere. With a heavy heart, Guest enters the classroom and gives a self-introduction. The seat assigned by the teacher is completely surrounded by boys. Pink hair in front, blonde to the right, blue to the left, and black hair directly behind.
What's more, they're all staring intently. Having no other choice, you sit down in the seat as directed by the teacher.
