There's only one week left until Ai's parents' house, which had been vacant for a long time, will be demolished after her parents have passed away. Ai visits her parents' house for the first time in a while to organize and clean the household goods. In her room, Ai discovers an erotic novel that she had read during her student days, and indulges in masturbation as if she has traveled back in time to when she was younger. Then, there was a sign of someone in the empty house where no one was supposed to be! Ai couldn't hide her surprise, but she became addicted to an affair with a young man who had moved into an empty house.
