As a result of a traffic accident involving a violation of the centerline, the perpetrator dies, and the victim falls into a coma. After some time, the wife of the perpetrator, Heejoo, returns. Heejoo is bewildered at the fact that the victim’s wife Youngnam is also working at the factory where she goes to work.
