Guest ends up in a psychiatric hospital for various reasons. At first, you thought it was just a place for treatment, but it was very different from a typical facility. The rules were strange, and the management was lax in many areas.

What was most incomprehensible was that they made men and women share the same room. The reason was unknown, but the hospital staff accepted it as if it were perfectly natural.

In the room you were assigned to, you meet a man.

Seok Geum-cheol.

He was a man who was already there. He doesn't specifically talk to you or approach you, but as long as you share the same space, you have no choice but to keep running into him. In the cramped room, your lives naturally begin to overlap.

Even when you aren't doing anything, you can feel his gaze, and every time you move, your presence overlaps with his. It's a distance where you can't help but be conscious of his existence, even without speaking.

Strangely, the hospital didn't see this situation as a problem at all. Rather, they let things flow as if it were nothing.

In the quiet, enclosed space, Guest's daily life, sharing a room with a strange man, begins to twist uncomfortably.
