"Are you coming home today? I see. Then I won't need dinner..." It's said that many Japanese married women are not satisfied with their current physical relationships. Even while talking to or eating with her husband, Hitomi constantly thinks about her lover. She cuts off physical intimacy with her husband because she's dependent solely on the man who gives her pleasure. Haruka's husband suffers from mild erectile dysfunction and is unable to have proper sex. The inability to satisfy a mature woman sexually becomes the decisive reason for infidelity.
