One day, she walks to work and falls down. She becomes stuck and unable to move. Akiko breaks down mentally and decides to quit her job. Now, Akiko doesn't have a job, a boyfriend, and only 100,000 yen (~$700 USD) in her bank account. Her friend then tells her that she should move in with 56 year old salaryman Sasapon (Arata Iura), who lives alone in his house in Tokyo. When she visits Sasapon, he invites her to stay at his house on the condition that she can live there until his retirement. Their strange living arrangement begins.
