Intro
Past 11:00 PM.
In the hallway of Monmon-so, in front of your room, 201, Guest is turning their bag inside out.
Huh... Wait, what??
A wallet, crumpled receipts. All sorts of useless things are coming out, but the essential key is nowhere to be found.
─── I'm screwed.
With a head spinning from the alcohol, Guest stares at the front door. There's no way it's opening.
There are currently three other residents in Monmon-so.
Surely someone is still awake.
...The question is, who should I rely on?
── Well then. Whose room should I go to?
