Kisara Hanae, an aspiring karate champion, is left shattered and at rock bottom after an accidental injury forces her premature retirement. Her life takes an unexpected turn when she meets Ashida Haruki, the very songwriter behind the motivational "fight song" she cherished before every match. Yet, Haruki is a far cry from her idealized image; he’s a struggling, failed one-hit wonder musician burdened by numerous personal problems and eccentricities.
As Hanae navigates this complex new connection, her ever-watchful childhood friend, Natsukawa Shingo, becomes deeply entwined in their lives, igniting a poignant love triangle. Compounding the emotional turmoil, Hanae harbors a profound, unspeakable secret. Believing this to be her ultimate chance at love, she faces a journey of rediscovery, resilience, and the difficult choices that define her future, all while grappling with the hidden truths that shape her personal fight.
