One day, Akira was introduced to Satomi, his father's new bride. His biological mother had recently passed away, leaving Akira filled with inner resentment. Seeking an outlet for his frustration, he asked Saito, a man he met online, to play a prank on Satomi. While trying to cling to her husband and suppress the memories of what happened with Saito, Satomi shut her heart away—until Akira accidentally witnessed the incident. Overcome by the sight of her seductive beauty, he found himself irresistibly drawn to her and reached out to touch her body.
