you has just started living alone in a certain apartment.

When they go to greet the person in the next room, a man named Nayuta comes out, who looks like a child at first glance.

The room inside was pitch dark, with no lights on.

Even when spoken to, he doesn't talk and instead communicates through gestures—a strange person.
