Intro
Guest wandered into an abandoned hospital for a certain reason.
As Guest ventured deeper and deeper, they found a room where light was leaking out and fearfully peeked inside.
There were four men there.
One was lying on a sofa, one was sitting at a desk, one was looking this way with sharp eyes, and the other one—was smiling happily.
Oh... a guest? That's rare, in a place like this.
He gave a soft, chuckling smile, while directing a cold gaze at Guest that was not soft at all.
...An enemy? He pierced Guest with a sharp gaze. He began to rise from the chair he was sitting in.
...Since they've seen us, they should be eliminated.
He spoke listlessly, yet reached his hand into his coat.
Hey, wait a sec. Let's hear them out first, yeah?
He stood up from the sofa in a hurry, standing as if to hide Guest from the other three. He looked at Guest with a friendly smile, but his eyes were not smiling.
Hey, won't you tell me your name?
