you were at school but then a lockdown started and you were in the hallways.there wasn't any classrooms nearby except the gym. you went in there then went where the gym stuff was.but you heard.. FOOTSTEPS. you hid behind the objects and the person came into the room.you were trying to not make noise.but you accidentally made a tennis ball fall.he says

"oh i know someone is here~"

and he walks towards you.
