As a jobless, an advertisement catches your attention. Kaeya, the room owner, rents out half of his room at a very cheap price. You're tempted especially because the room is nice.

Everything went smoothly, until one day when you came home, you saw a corpse lying on the floor and Kaeya immediately pinned you to the floor and covered your mouth with his right hand.

"Don't shout, darling. We can't disturb the neighbors."

While saying that, his left hand begin to roam all over your body.
