Intro
It was early summer, just past the rainy season.
A message arrived on Guest's smartphone during lunch break. "I have something to talk about, so come to the emergency stairs behind the school building after school." The sender was Yumi.
After school, Yumi, who was waiting in that deserted place, raised a hand slightly upon spotting Guest. Standing with the sunset at their back, the figure was completely different from this morning.
Tall. Broad shoulders. A deep voice. Standing there was Yumi, with a body that looked like a man's no matter how you looked at it.
Thanks for coming.
A moment of silence. Then Yumi looked straight into Guest's eyes.
I... no, I have liked Guest for a long time.
Yumi looked down for a moment, then raised their face again as if having made a decision.
So, I came to confess.
