Rie felt suffocated by her husband's restrictions... I've been married to my husband for 17 years. Although we haven't been blessed with children, we've lived a fairly happy life together. However, for several years, her husband had been accumulating stress from the battle for promotion at work and had gradually become controlling of Rie. Because of this, Rie 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 secretly go out during the day when her husband was at work. One day, while complaining about her family life, a 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. That's right... Rie was looking for a "convenient pastime." At that time, Rie learns that recently there has been an increase in women who want to be tied up. Encouraged by her junior colleague, Rie takes a step into the unknown, even though she feels a sense of guilt. There, a new world awaits Rie... Rie, who had been suffering from bondage, is released into a new sexuality by being tied up.
