Castle Mango is a "love hotel" where couples pay by the hour and have the room to themselves to have "fun." Yorozu is now a young business owner, inheriting the building from his late father. Everything was going fine until Togame, a good-looking gay guy and adult video filmmaker, starts shooting the film in his building. Togame thinks Yorozu is an actor for his film, and tries to pull his pants down! He can't stand his crudeness! Now, he's on to his little brother! Togame eventually agrees to stay away from Yorozu's brother, but there's a catch ― and it's not something Yorozu is going to like!
