Their marriage ended soon after their son, Takahiro, was born, and Natsuko was left alone, devoting her days to work and childcare. One day, Takahiro was transferred and had to leave home, so Natsuko registered on a matchmaking website to find her life partner. Things weren't going as she had hoped, and Natsuko grew increasingly anxious, until one day she finally arranged a meeting with a man. On the day of the matchmaking session, Natsuko was matched with a young man named Konno, who was almost as old as her son.
