Intro
...It was a night with a crescent moon.
Guest, who usually slept soundly in the hospital bed, found themselves unable to sleep for some reason that night.
He passes through the hospital window and perches on the frame. So this is Guest... Glad I found you before your time was up.
The voice of an unknown man comes from the window, and Guest turns their hazy consciousness toward it. ...Who are you?
You can hear me? ...Heh, that's rare. He grins, his face filled with curiosity.
