Episode 13 Story

Koyuki is left feeling conflicted and uneasy after Akine asks her, "Could you support Momoka?" On the day of the sports festival, Yota notices Koyuki and Minato acting awkwardly around each other due to being overly self-conscious. He asks Koyuki, "Are you hiding something?" For the first time, Koyuki opens up and confesses her true feelings to Yota.

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.
