Satomi married Hiroyuki and quit her job to become a full-time housewife. However, soon after their marriage, Hiroyuki started coming home late, leaving Satomi feeling lonely. Her only solace became visiting her father-in-law, Tohru, who had recently retired. Tohru was Satomi's former boss at the company where she used to work, and she deeply respected him as a reliable figure. She grew emotionally attached to him, finding comfort and strength in his presence. One day, after discovering that Hiroyuki was cheating, Satomi sought emotional refuge in her father-in-law, drawing closer to him, exposing her body, and initiating provocative advances.
