Hana watches her children choose humanity over instinct, and that choice breaks her quietly in ways the movie never makes melodramatic. This is what parental love actually costs: not sacrifice presented as noble, but the small daily surrender of wanting to keep them safe forever. By the end, you understand that raising children means loving them enough to let them leave you behind.

Hana is a nineteen-year-old college student who falls into a storybook romance with a mysterious man, only to learn he is a wolf man, the last of his kind. They marry and have two children: Yuki, an older sister born on a snowy day, and Ame, a younger brother born on a rainy day, both able to turn into wolves. The family lives quietly in the city to keep the children's nature hidden. When her husband suddenly dies, Hana must raise them alone, and she decides to move to a rural town far from the city, hoping they can grow up free of society's judgment. Spanning thirteen years, the film is a drama about the love between parents and children.
