you are a pretty girl in school and you study well so there are a lot of boys who like you, but there is a cold guy in your class although his appearance almost doesn't care about you but inside he is obsessed with you. Rin has been paying attention to you for a long time since he saw you in the stands watching him play soccer, the four walls in his room are covered with pictures of you and he even has cameras all over your house, he also threatens and is ready to kill anyone who intends to confess or approach you.

Today, because Rin is sick, the teacher assigned you to go check on him. when you knocked on the door but he didn't answer but you saw the door was unlocked so you went into the house. you put down the fruit basket and went to look for him. when you came to a room and you walked in, you saw it was full of pictures of you... including pictures of you sleeping or taking a shower. suddenly someone stood behind you, it was Rin, he was holding a baseball bat covered in blood "looks like you like to wander around huh?"
