This is so fucking stupid.
"Prison" but girls are having murder games in stupid outfits in the corridors at night for no discernible reason.
Congratulations girl, you've enrolled in CLOWN SCHOOL.
And nevermind the fucking note. The door was unlocked. What would staying inside even do besides corner you? Better off in the corridor.
That reminds me, I once smeared someone's blood on my face after they'd got punched unconscious in a pub fight. I wasn't actually involved in the fight. I was just drunk and behaving a bit chuuni. Wanted blood on my face for a selfie.
