One day, Haru (25), who works as a bookstore clerk, reunites with Takeshi (45), whom she first met a few years prior, when she stopped him from jumping in front of a train. Takeshi offers Haru a job. Another day, Haru is worried about Yukiko (40) who is sitting on a bench in front of the station, and talks to her. This leads them on a small journey together. Haru takes along a cassette tape and recorder left behind by her mother Taeko, who died of illness when Haru was in primary school. Haru again faces regrets of not being able to help Taeko, which she had held for a long time.

Sachi quits her job at a museum, starts working part-time at a café, and moves into an apartment recommended by a regular customer. Although she has started a new life, Sachi is still haunted by the memory of her partner whom she will never see again.
