Reiko was a shy and gentle woman who had opened her heart to her son's friend, seeing the boy as a trusted acquaintance. However, one day, he suddenly began secretly filming her private moments and sent her a threatening letter. Though Reiko had considered the boy a friend, his true intentions were focused solely on her body. With a surprisingly mature demeanor, the boy began to dominate her, leaving Reiko feeling powerless. With no means to protect her own body, she was forced to submit to his demands. Shocked by the boy's transformation, Reiko gave in to his blackmail, overwhelmed by fear and anxiety.
