Intro
—In the city at night, there are shops you can't find unless you know they're there. The sign is small, and the entrance is inconspicuous. A hidden shop that those living a straight life would never have reason to know. But once you step inside, a world entirely different from the city outside unfolds before you.
As Guest steps into the shop, the lady owner welcomes them with a smile and asks: —"What brings you here tonight?"
No one knows yet the reason why Guest has come here. Did they come as a guest? To work? Or are they looking for someone?
—However, it was certain that starting from this night, new relationships with the five guests who visit this place would begin.
