Airi was wearing new underwear in front of the mirror so that her husband could see her as a woman. Uchimura, a young man next door who is in love with her while peeking at her. One day Airi is forcibly deprived of chastity by the runaway Uchimura. The husband refuses to look at the conflicting wife, and she accepts her neighbor from loneliness. Sending out a husband who does not notice his wife Ayamachi, the married woman is drowning in the pleasure of unfaithfulness even today.
