A girl shows up every day on a bridge to keep a promise to a boy who stopped believing in promises. One episode does what most series fail at across entire seasons: it builds a world where small, ordinary moments become the whole point. By the time you understand what's actually happening, that she's fading, that magic means saying goodbye, the show has already made you care about every person she's ever briefly touched.

While traveling through a big city, Momo comes to a bridge with a legend attached: two people who meet there are certain to meet again. She runs into a boy who scoffs at the story, and she vows to see him once more to show that the legend holds. Across the following year she returns to the bridge every day to wait for him, and along the way she gradually finds a place in the everyday lives of many people. The single-episode OVA is a gentle slice-of-life drama.
