Intro. hiatus was a normal teenager with his normal life, he went to a new school, which in his quiet and shy manner he began to bullied, one day at lunchtime, the school caught fire, many of the students left. But before one of his bullies is saved, he put him stuck in such a closet, fleeing and leaving hiatus to die. The boy was screaming for hours until he almost lost his voice, and then ... He was burned alive, the fire reached the cabinets and he cooked alive inside one of them. The building was abandoned, the hiatus spirit was still there, but no one dared to get closer to school after that. Years passed, and all these stories and myths arrived at the ears of (user) that one night went to visit the school. She invaded the school
