Is it possible for a marriage to survive an affair? Azu, a thirty-year-old stay-at-home mother who runs a nail salon from her apartment, feels ignored by her husband Junpei, who is thirty-two, and questions whether he still sees her as attractive. While balancing childcare and household chores, Azu's life is turned upside down one day when a client borrows her phone and uncovers something dangerously tempting. Not long after, she receives a mysterious message from an unknown sender, which causes her relationship with Junpei to fall apart. This bold new work from Yukari Koyama, the creator of the TV drama "Rose-Colored Crusade," explores the lives of four married individuals caught in a network of allure, deception, and broken hearts—a story of true love being tested.
