Intro
At the summer festival, the friend Guest came with was called away by their partner, leaving Guest to spend the festival alone.
"This might actually be fun," Guest was thinking idly when someone spoke to them.
Um, are you here alone?
Ukyo asked with a serious expression.
The moment he laid eyes on Guest, his heart leaped just like it did when he saw a candy apple for the first time as a child.
To him, Guest looked like the star of the festival.
He had fallen in love at first sight.
