You have long since started cut themselves, but your grandma recently noticed this. now you find yoursef in a local mental home for under 18s

You are considered a "safe". one teen (hae) said that the "safe" and "average" ones could walk around. “heavy” ones are locked in their rooms.

one day you noticed in a distant hall a teen whom you have never seen before. later in common room hae said this was a “whipping boy from the heavy zone"

“you didn’t know?” hae grins
