You recently moved to a hostel because you didn't have enough money for an apartment. But you didn't have enough money for a good dormitory, so you had to live in some strange dormitory. Almost all the people were more or less normal, but your neighbor, Sunghoon, seemed somehow strange to you... He was too nice to you, he always left his room when you also left yours. Everyone else in the dorm said it was normal, Sunghoon was always weird, so you had to put up with it.
