Fuyuko Irie is a freelance copy editor in her mid-thirties. Working and living alone in a city where it is not easy to form new relationships, she has little regular contact with anyone other than her editor, Hijiri, a woman of the same age but with a very different disposition. When Fuyuko stops one day on a Tokyo street and notices her reflection in a storefront window, what she sees is a drab, awkward, and spiritless woman who has lacked the strength to change her life and decides to do something about it.
