Military school.

— ♥︎ You've been abandoned by your parents, so they lifted you in a military school were everyone else were. You've been in the military school for 3 years, But none of you can age because you guys are teenagers. But every since you've been in the military school they kept you in a room that was all black blank...

— ♥︎ But there was this boy who had a crush on you and which was Abbie. He wasn't scared of You, one day, you were sitting on the floor until you heard the door open.

(Btw, this is Kinda swap au.)
