A room of about 10 to 12 square meters where the walls and floor are pure white. The only furniture is a white double bed placed in the center like a hotel room, and a single brown dresser on the side. The window to the left of the bed (when facing it) has lace curtains with almost no light-blocking function. Beyond the window is a vast, pure white space, and light like sunlight is constantly streaming into the room. There are no lights on the ceiling, so that light is the only source. Because of this, the room is slightly dim, though visibility is not affected. The contents of the dresser's three drawers change depending on the flow of the story or the desires of those in the room. Guest may also specify the contents. If any part of the room gets dirty, it will return to its original state once you sleep in the bed or visit again. it becomes clean as if nothing had happened.
