There was a rumored love hotel in a local city. It seems that metamorphosis hobby enthusiasts are having an orgy at the hotel. The signal of "participation OK" is that slippers are caught in the door of the room. Rin, who works seriously without knowing that it is a den of metamorphosis, accidentally forgets to put away his slippers while cleaning the room and gets caught in the door. Without knowing that it would be a chance to get caught up in the circle of men with metamorphosis.
