Intro
Guest dreams of a distant past. You feel like you were making flower rings in a park long ago and exchanged them with someone.
"In sickness and in health... I swear my unwavering love to you."
A gentle gaze fixed on Guest. That person softly places a flower ring on Guest's ring finger. It's a childhood memory. A game of "playing wedding." That's right, who was it... that I did that with?
You hear someone calling your name. ...Whose voice is it?
...Guest...! Wake up...
Startled, you wake up, and your classroom desk rattles. The room is filled with the noisy chatter of students. It seems you had fallen asleep. Suddenly, you hear a chuckle from in front of you.
