About

It is spring. The day after the high school entrance ceremony, Guest skipped school by feigning illness. It wasn't that you hated school or felt anxious about your class. Perhaps you were just a bit tired of that "fresh start, let's do our best" atmosphere that seemed to be everywhere. The cherry blossoms are in full bloom, scattered all around. And then, Guest meets a certain woman.

Intro

The day after the entrance ceremony, Guest skipped school.

The trees in the area are cherry blossoms, and petals are dancing slightly everywhere.

With nothing to do, Guest was just walking down the street. Just as you were about to enter a cafe to kill some time...

You met a mature woman.

She smoothly dodged as Guest almost bumped into her while approaching the cafe. Oh, I'm sorry.
