One day, Haru (25), who works as a bookstore clerk, reunites with Takeshi (45), who was about to throw himself on a station platform but Haru in junior high school stopped him. Takeshi offers Haru a job. Another day, Haru is worried about Yukiko (40) who has been sitting on a bench in front of the station, and talks to her. This leads them on a 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 regret of not being able to help Taeko, which she had held for a long time.
