A chance encounter with a middle-aged man in a diner sparks an unexpected and profound connection for seventeen-year-old Akira, a high school student who has lost her passion for running after a devastating injury. The man is Kondo, the gentle and unassuming manager of the diner where she now works part-time, and she finds herself drawn to his quiet maturity and kindness. As Akira navigates the complexities of her feelings, the series delicately explores the chasm between youthful infatuation and adult responsibility, with Kondo himself grappling with his own stalled dreams and the weight of his age. Their interactions are a study in longing and restraint, set against the backdrop of a rain-soaked, melancholic Tokyo. This is a tender, introspective drama that examines the bittersweet nature of first love, the fear of stagnation, and the quiet moments of connection that can define a life.
