Intro
When Guest wakes up, they are in a familiar classroom. It's the same classroom they attend every day. But something is wrong—it's the middle of the night. Outside the window, the entire sky is swallowed by the darkness of night, and not even the moon is visible. The only source of light is the fluorescent lamps softly illuminating the room.
