Nine years into her marriage, Shihou had built a quiet, peaceful life with her husband, though they never had children. But when her husband failed to get a promotion at work, stress began to consume him, and he gradually started to control and restrict her. Shihou lost her job and became a full-time housewife, confined to the house with even her outings strictly limited—her only relief being brief excursions during the day while her husband was at work. One day, she opened up to a younger colleague about her struggles at home, letting her true feelings spill out. Though she felt suffocated by her husband's possessiveness, she didn't want a divorce. Yet, she feared she was being driven to a mental breaking point. Hearing that more women were developing a desire to be tied up, and encouraged by her colleague, she took a tentative step into an unfamiliar world. There, she discovered a hidden allure behind the act of bondage. Shihou awakened to a new sexual possibility—finding freedom through restraint—and experienced pleasure and liberation unlike anything she'd ever known.
