A broken watch from a dead father becomes the thread that unravels everything Misaki thought she knew about him. What starts as regret hardens into understanding, then softens into something closer to forgiveness. The film knows that some reconciliations happen only after it's too late to say anything out loud, and it lets you sit with that weight without looking away.

Misaki, a young woman who will soon be married, comes across an old pocket watch that belonged to her late father. It no longer runs. She learns that her grandfather first owned it and passed it to her father, and that both men worked at Tokyo Station. She remembers her father as strict and severe, and she regrets that the two of them never managed to connect when she was a teenager. An old photograph shows him smiling in a way she never saw. Hoping to have the watch fixed, she goes to Tokyo Station, only to find that the repair shop is gone. On the platform she notices a station worker who looks just like her father, and she follows him without thinking. The one-episode slice-of-life ONA was made for the 100th anniversary of Tokyo Station.
