Soon after getting married, Saiko found herself living alone due to her husband's work transfer. In their married life, she constantly suffered from sexual frustration. For her, the only solace was self-care at the beauty salon. One day, she became interested in an experience the therapist proposed—bondage. When her wrists were tied, she felt an intense pleasure and stimulation unlike anything she'd ever known, surprising herself as she became obsessed with the sensation. Captivated by this new thrill, Saiko returned to the salon and chose to have her entire body bound with rope. In that moment, shame and pleasure intertwined, and she was completely consumed by the ecstasy of tight bondage.
