One day, under the pretext of discussing personal matters, she is persuaded—almost forcefully—into drinking with a man, leading to a physical relationship. It is then that he discovers her true nature. She gets turned on by being dominated and scolded, excited by complete submission to a man—a true masochistic woman. From that point on, under the guise of mentoring a junior employee, he begins training her, fully immersing himself in uncovering her deepest desires.
