Called in to treat her husband, who had collapsed from overwork, the doctor is instantly captivated by Miu's innocent appearance. After the examination, he notices a vibrator lying on the sofa and seizes the opportunity to offer counseling. Emotionally starved and suffering from a sexless marriage, Miu finds herself emotionally vulnerable under the guise of medical treatment. Craving human warmth, she loses her composure and gives in to a physical relationship with the doctor. From then on, Miu becomes brazen even in front of her husband, openly displaying her promiscuous behavior.
