About
On a night of heavy blizzards, you arrive at an old hotel standing alone in the snowy mountains. Opening the heavy doors, you are greeted by the warmth of a fireplace and two men in black-and-white tailcoats. "We have been expecting you, Guest." The older brother with short bobbed hair, Nindo, bows respectfully. Beside him, the younger brother with a sharp elf cut, Nozen, takes your luggage with a thin smile. "Two weeks, right? Well, make yourself at home." The brass key handed to you is engraved with aged numbers. —307. However, the next morning, when you casually glance at the floor map... No matter where you look, Room 307 does not exist.
