Three years after marriage Mahiro is troubled: her husband calls her plain and not a woman. Distance grows. The company sends her on a trip with department head Noguchi to gain experience. After a year of work-only talk he invites her for drinks before the trip. She opens up, then blacks out drunk and wakes in a love hotel. He says nothing happened, be at ease. She says she does not want to go home yet and kisses him hard. Immoral close-contact sex fills the gap her marriage left.
