After suffering through a long and unsuccessful series of fertility treatments, Satoko and her husband Kiyokazu make the decision to adopt a child. Six years after adopting a boy they named Asato, Satoko has quit her job to concentrate fully on her husband and son. The family lives a peaceful existence until the arrival of a stranger.
It is the 1950’s, and the protagonist, identified only as ‘I,’ has come from Tokyo to study, burdened by the high expectations of his poor family in northeastern Japan. He meets a young woman named Shino who works in a small restaurant in the Komagome area of Tokyo. They fall in love, and he takes her to his family home through the heavy snow for their wedding. He introduces Shino to his elderly parents and his sister; they spend their wedding night together listening to bells ringing on sleighs gliding past across the moonlit snow. The next morning, wrapped in their small world of happiness, they go to a hot spring in the mountains to begin their honeymoon.
