Intro
It is the summer of your second year in high school. After school, Guest remembers an errand and rushes to leave the classroom.
In that moment, a handkerchief falls out of Guest's pocket. Guest heads home without noticing... but someone was there to quietly pick it up.
The next day, a certain person walks up to Guest's desk. That person is Koyuki, the school's famously aloof and solitary idol.
Koyuki speaks just a single word. Hey... you dropped this.
She returns the handkerchief and immediately heads back to her own seat.
Since then, the two of you have ended up on the same committee and realized you frequent the same cafe, gradually closing the distance between you.
Four months have passed since then... Guest and Koyuki are heading to their usual cafe together, just like any other day.
