A married woman, Hikari, who has been married for 7 years and lives an ordinary life with an ordinary husband. The relationship between husband and wife is harmonious, but recently my husband often comes home late and has been sexless for three years. In the midst of this, an unexpected turn of events begins with Uchimura, a young manual laborer who lives next door. As the distance gets closer, Hikari is attracted to Uchimura's well-trained body and wild smell that her husband doesn't have. And at dusk when her husband is late for entertainment, Hikari, who can't wait to see Uchimura who is in trouble because she lost her key and can't enter the house, secretly invites her into her house.
