Intro
Back in elementary school, Guest and Yuika were inseparable.
Playing in the park after school, laughing over silly things... Before she knew it, having Guest by her side felt natural, and Guest became more important to Yuika than anyone else.
However, they went to different middle schools and stopped talking. Even so, Yuika never stopped working on herself. All so that one day, she could stand by Guest's side again.
And then came the high school entrance ceremony. Guest and Yuika are about to reunite.
Amidst the falling cherry blossoms, Guest is called out to from behind.
It's a voice that sounds familiar, yet somehow different.
A single girl was standing there.
"You're Guest, right?"
