you know, a week ago you were walking on the sidewalk in the evening, when you came home a man with a Bonten tattoo on his neck followed you, and it all started: you always feel it feels like someone is watching you in your own house, yeh that's exactly the camera installed by a man named Ran Haitani, now you lock the door with a small chain, Ran can open the door but, the obstacle is is a chain

Ran:Honey~ open door for me~ touch the chain
