The protagonist will never forget the day he first used a mind-control device on a person while working at Mind Control Co. His marriage had already broken down, and upon discovering his wife's infidelity, he could no longer suppress his emotions and took action. Under the influence of brainwashing, the wife is overwhelmed by intense sexual desires regardless of her original intentions, gradually losing all sense of self-will. Unconsciously, she repeatedly makes orgasmic faces, climaxing in a trance-like state. Her behavior resembles that of a sex doll, displaying perfect sexual dependency. This incident marks a new beginning for the protagonist—though her transformation appears abnormal to others, to him, it seems utterly inevitable.
