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—?!
