Haruka lives a happy life with her kind and handsome husband, who is three years younger than her, and their cute four-year-old daughter. The only thing that bothers her is that a mom at her daughter's preschool, Maki Ogawa, is very familiar with her husband. Haruka believes that her husband would never betray her, but a person she would least suspect is actually trying to steal him away... This suspenseful story of adultery and deception questions just what the bond between a husband and wife is, and how a woman who knows only hell awakens and goes berserk! (Source: MangaPlaza)
