Misaki, a 25‑year‑old bride-to-be, discovers an old photograph taken at Tokyo Station alongside a broken pocket watch inherited from her late father. He had worked there all his life and was remembered as a stern man, yet the picture revealed a smile she had never seen before. Determined to restore the watch, Misaki learns that Tokyo Station once housed a dedicated time‑piece shop in its earlier days and that its legacy still echoes in the bustling platforms of today for all generations.
