Episode 12 Story

As Koyuki spends more time talking with Minato, she begins to harbor special feelings toward his casual gestures and expressions. Amidst this change, a first-year student named Momoka suddenly approaches Koyuki, narrowing the distance between them. Meanwhile, Miki goes out on a motorcycle touring trip with Yota. While Miki considers Yota just a friend, Yota holds complex feelings of his own.

Introduction

Koyuki Hikawa is a high school student who struggles with social interaction and tends to build a "wall" between herself and others. She spends her days quietly, never hanging out with anyone except her childhood friend, Miki Azumi.

However, her peaceful isolation is suddenly interrupted when Minato Amamiya, a boy who has no sense of personal space, starts aggressively closing the distance between them—?!

The solitary Koyuki, the school idol Miki, the overly friendly Minato, and the gentle, calm basketball player Yota.

Clumsy, frustrating, and yet incredibly endearing—the curtain rises on a coming-of-age ensemble drama woven from the misunderstandings of youth.
