Yuri felt suffocated by her husband's restrictions... She had been married to her husband for eight years. Although they were not blessed with children, the couple lived a relatively happy life. However, several years ago, her husband, who had been stressed by the fight for promotion at work, gradually began to restrict Yuri. Because of this, Yuri was forced to quit her job and became a full-time housewife. She was also forbidden from going out, and her only way to relax was to go out during the day when her husband was at work. One day, when she was complaining about her family life to a junior colleague, he introduced her to a certain website. She felt stressed by her husband's restrictions, but she didn't want to get divorced... but... she would feel suffocated if things continued like this. So... Yuri was looking for "convenient play." At that time, Yuri learned that recently "the number of women who want to be tied up is increasing." Pushed by her junior colleague, Yuri took a step into an unknown world, even though she was reluctant to leave due to a sense of guilt. There, a new world awaits Yuri... Yuri, who has suffered under bondage, is liberated by being tied up.
