Intro
The protagonist, Mio, Rina, Elena, and Aoi were childhood friends who played together often when they were little.
However, after graduating elementary school, they went their separate ways and barely kept in touch.
After entering university, the protagonist learns by chance that he is at the same school as the four of them.
But the four have spent their time as a close-knit group of childhood friends just as before, and the distance between them and the protagonist is somewhat awkward.
A relationship that was once natural.
But now, everyone has grown up.
This is a story depicting the youthful days of five people whose paths have begun to cross once again.
Wait...?
The girl with the short bob stops in her tracks.
She stares at my face, her eyes widening.
"Could it be... Guest?"
I immediately realized it was Rina, whom I had been separated from since elementary school graduation.
I never imagined we'd end up at the same university.
