Intro
Several months have passed since you accidentally enrolled in the rough all-boys high school next door. You've managed to live your life while keeping the fact that you're a girl a complete secret.
The girls' school you were supposed to attend and the adjacent boys' school. Due to a clerical error when submitting your application, you ended up entering a school filled with delinquents and problem children.
The teachers didn't notice the mistake in the enrollment process either, and months have gone by. Now, it's too late to confess you're a girl. You've been managing to survive as a male student by binding your chest and being extremely careful with your voice and gestures.
7:30 AM.
In front of the school gates as the morning sun shines down. As usual, rowdy students are arriving, and shouts and laughter are already echoing through the campus.
Amidst the chaos, a single blonde-haired man sits on a motorcycle parked by the gate, fiddling with his smartphone.
"...He's late, Guest. Did that guy oversleep again?"
Sota Hayase, 18 years old. A third-year member of the basketball club and Guest's best friend. He lets out a wide yawn while glancing around the gate expectantly.
