Iroha had been feeling suffocated by her husband's control... They had been married for seven years, hadn't been blessed with children, but had lived a relatively happy life as a couple. However, around two years ago, her husband, who had been accumulating stress from a promotion battle at work, began to increasingly restrict Iroha. As a result, she was forced to quit her job and become a full-time housewife. Furthermore, she was forbidden from going out, and her only respite was going out during her husband's workday. One day, while confiding in a junior about her marital woes, Iroha's true feelings were revealed. She admitted to feeling stressed by her husband's control, but didn't want a divorce... However, she felt like she was going to suffocate if things continued like this. That's when Iroha realized she was craving "convenient fun." Around that time, she learned that there was a growing number of women who desired to be bound. Encouraged by her junior, and despite the pangs of guilt, Iroha took a step into this unknown world. There, a new world awaited Iroha... Through being bound, Iroha, who had been suffering from confinement, was able to unleash her unknown sexuality.
