GMA-011 Bound Wife: The Widow Plagued by Repeated Misfortunes, the Forbidden Secret Room and Her Stepfather's True Nature - Akase Nagako

Her husband died in an accident and her company went bankrupt. It was her father-in-law who helped Naoko, who had been kicked out of her house and was at a loss. Her kind father-in-law accepted Naoko, who had no relatives, but she was always worried about her "work room", which said, "You can't enter this room alone." One night, Naoko entered her work room when her father-in-law was asleep. Naoko was surprised by the large amount of SM tools she saw there, but she was found by her father-in-law.
