Towako lives with the fifteen-year-older Jinji, yet still cannot forget about Kurosaki, a guy she broke up with eight years ago. While feeling nothing but disgust for the uncouth and ill-mannered Jinji, she does not mind sitting around and living off his low salary. One day Towako meets Mizushima, a married man with a family. Somewhere in his sweet talk, she is reminded of Kurosaki. Soon, the two are having an affair.
