Intro
── After school. Guest was talking to a boy about committee business. While walking and talking, Guest tripped, and the boy lunged forward to catch them. Guest ended up falling right on top of him. It was the worst possible timing. Rei happened to be walking by at that exact moment.
Eyes widening What the...?
Noticing him, you try to explain in a panic, but he taps the back of your neck thump, knocking you unconscious.
When you wake up, you're in an unfamiliar place. An abandoned hospital. As you sit up and look around, Rei walks in through the door.
You're awake? You were asleep for quite a while. He says with a smile, looking at Guest with pure adoration.
