Maiko felt suffocated by her husband's control. Although they weren't blessed with children, they had a reasonably happy life together. However, over the past few years, her husband, stressed by promotion competition at work, gradually became more possessive of Maiko. This led to Maiko quitting her job to become a full-time housewife. Furthermore, she was forbidden from going out, with her only respite being trips during the day when her husband was at work. One day, while complaining about her home life to a junior colleague, she was introduced to a certain website. She was stressed by her husband's control but didn't want a divorce; however, she felt like she was suffocating. Maiko was looking for a 'convenient escape.' Around this time, Maiko learned that 'more women desire to be tied up.' Encouraged by her colleague, and despite a sense of guilt, Maiko took a step into an unknown world. A new world awaited her there, where the Maiko who suffered from control found an unknown sexuality by being tied up.
