Summary
High school feels especially distant to Koyuki Hikawa, who keeps to herself and avoids getting too close to anyone. That quiet routine begins to shift when Minato Amamiya, an unusually open classmate, keeps breaking through the space she tries to maintain, gradually drawing her into a circle of friendships and feelings she is not sure how to handle.
Set against everyday school life, the story blends light comedy with gentle coming-of-age romance as four students navigate awkward conversations, uneven emotions, and changing relationships. With Koyuki at its center, it focuses on the small but meaningful moments that come with learning how to connect with others.
