Married for eight years, Yuri and her husband had built a modestly happy life together, despite not having children. But over the past few years, her husband began suffering stress from work pressures and gradually started controlling Yuri—forcing her to quit her job and become a full-time housewife. With strict limits on going out, the only time she could breathe freely was during the hours he spent at work. One day, while confiding in a junior colleague about her domestic struggles, she was introduced to a new website. Though she didn't want to divorce, the suffocating control was driving her to the edge. Torn between duty and desire, Yuri began seeking what she called "convenient fun." Then she learned that more and more women were developing a secret craving to be tied up. Encouraged by her friend and unable to resist her curiosity, she took a step into the unknown. A world awaited her—one where Yuri, long tormented by bondage, would finally discover thrilling new sensations.
