Tsukishiro Yukina runs because she has to, not because she remembers why.
Once driven by passion, she now drifts through races on habit alone, carrying the quiet weight of defeat.

She crosses paths with Koba Natsuki, a celebrated actress standing on the edge of a defining performance. As Yukina trains toward Nationals and Natsuki navigates the pressures of expectation, fame, and family, an unexpected connection takes shape. One that stirs something long dormant in Yukina and quietly challenges Natsuki to step beyond the roles she’s been assigned.

Together, they begin to rediscover things they thought they’d lost—purpose, resolve, and the courage to move forward.
