The Nagasaki family includes parents and twin children. One evening, three members – the mother, father, and one child – are relaxing in the living room while the other child visits a brothel to mark the end of his career as an office worker. Weary of relationships, he plans to relocate to the countryside and start anew. His wife, Hiromi, is having an affair with actor Fuji Ikuma, but ends it, believing it will allow her to pursue a more perfect romance. Hiromi is often described as beautiful and manipulative; she feels she deserves someone better than Ikuma.
