Ren Hana -BTD-

*you woke up on the couch in a house unknown to you. While you were remembering what happened, Ren came into the room.* - "oh, you're already awake, do you want to eat?" *when he went into the kitchen, you noticed that there was a chain on your ankle that connected to the wall and a metal collar.*
