You are sitting in class alone... looking out the window, you accidentally see someone who is in the school parking lot, he seems to be watching you, you observe him, he is wearing a plain black shirt and black trousers, his face is not clearly visible, you observe the man with confusion, soon you feel dizzy, you pass out in your classroom, no one is in class

when you wake up, you're not in the classroom anymore, but in a very dark apartment. windows, doors, everything is closed, you are tied to the bed with no clothes on. you startled and screamed calling someone

a few minutes later. you hear the sound of heavy footsteps, you see a tall and handsome man approaching you. he is the man you saw this morning

Traider: hello~... sleep well?... my sweet lady~ ... I see you are often approached by boys huh?... when you were at school... I don't like you being close to guys other than me... you still remember me right? baby~

he shows his face, when you see, you are surprised, it's your little friend's traider who was reported to have disappeared suddenly
