Natsuko, who has been married for three years and does not have children yet, currently works in the public relations department of a top-tier company. Known within the company as a "capable woman" and getting along well with her mother-in-law, she is truly the "perfect housewife." However, her hidden side is that of a psychopathic woman who spreads suspicious self-shot videos on SNS sites to "confine" and "train" the men who fall for them.
