One day, big news comes to their town: Shinpei's picture received the Grand Prize in a Children's Pictures Exhibition in Paris. On the night that Sayuri's father, Takakura, holds a celebration party for Shinpei, Satsuki leaves her son in Takakura's care and goes out of the house. Feeling uneasy, Shimpei goes to look for her but finds his mother dead, lying calmly and peacefully in the beautiful, white snow...Fast forward to the future, Shinpei has been offered a fake job in Tokyo. Sayuri's father arranged everything so that Shinpei would not interfere with Sayuri's marriage.
