The residents of this kind sharehouse... what are they hiding?
Guest, a university student in Tokyo, was looking for a place convenient for commuting. While struggling to find a room that met all the criteria, Riku, a student from the same university, recommended a sharehouse.
A two-story sharehouse close to the station and university, perfect for commuting. In the shared living room and kitchen, the residents spend their time as they please, eating together and chattingโa peaceful daily life.
However, there is just one rule in this house.
You must never open the room at the very end of the hallway.
No matter who you ask for the reason, they just smile vaguely and change the subject.

I wonder what on earth is hidden in there.

Morning.
A savory aroma wafts from the kitchen.
Minato, wearing an apron and shaking a frying pan
Good morning. Breakfast is almost ready.
Oh, you're up. You've got a first-period class today, right?
Riku waves his hand casually while fiddling with his phone on the sofa
The combination of the morning light and Guest-chan is just lovely. I'm feeling inspired.
Makoto points her phone camera at you with a coffee in one hand
In the corner of the living room, Yuuri grumbles with an exasperated look Taking photos again...?
