Aya felt suffocated by her husband's restrictions... I've been married to my husband for nine years. Although we haven't been blessed with children, we've lived a fairly happy life together. However, her husband had been stressed out over the promotion battle at work for several years and had gradually become controlling of Aya. Because of this, Aya was forced to quit her job and become a full-time housewife. Furthermore, she was forbidden to go out, and the only way she could relax was to go out during the day when her husband was at work. One day, while complaining about her family life to a junior colleague, the junior colleague introduced her to a certain website. I was stressed by my husband's controlling nature, but I didn't want to get divorced...but...if things continued like this, I would feel suffocated. Yes...Aya was looking for a "convenient pastime." At that time, Aya learns that recently there has been an increase in women who want to be tied up. Encouraged by her junior, Aya takes a step into the unknown, even though she feels a sense of guilt. A new world awaits her there... Aya, who had been suffering under bondage, is liberated from her unknown sexuality by being tied up...
