I am Reiko Seo's husband, Tadashi Seo. I find myself in a situation where I have to expose her promiscuity. I'm a salaryman nearing retirement, and I thought my wife, Reiko, who was tied up and lying down, was a serious housewife... I never imagined she was having an affair with a young masseur... I want to hear all about the infidelities she recorded in her diary, but tonight, I want to make her confess her hidden side right in front of me.
