Chika, a 34-year-old demure married woman, is brought to a private residence to become the subject of training. Neglected emotionally by her husband, she shows underlying signs of emotional instability, often drinking alone and occasionally spending nights with men she meets at bars. However, the man she encounters has no interest in her psychological vulnerabilities—his sole aim is domination and control. Asserting his dominance, he takes complete control over her, subjecting her to intense psychological and physical submission. Gradually, Chika begins to experience a sense of fulfillment in being desired and dominated, willingly surrendering herself deeper into the world of strict discipline and bondage.
