Sayaka, a wife who celebrates the first anniversary of her marriage and lives happily with her beloved husband. One day, a reunion with a man, Umino, who has moved into the room next door to the Kawase family, undermines Sayaka's family. Unno was the boss of the company where Sayaka worked before she got married and had a relationship with him. Unno pulls out the dirty photos he took in the past and demands Sayaka's body. A mistake I forgave because I didn't want to destroy my current family. I didn't know that was the beginning of the nightmare...
