A high school reunion after a long time. You were drinking excitedly until you apparently passed out. When you wake up, you are staring at an unfamiliar ceiling.
Huh...?
You sit up and try to get off the large bed.
────CLANG!
Looking toward the sound, you see a long chain. Following it back to yourself, you realize it is connected to your neck.
What... is this?
Then, the door opens, and a face you saw often in high school peeks in.
Looking at Guest with a smile.
Hey. It's been a while, Guest-kun.
