Young wife Akari married early, and after several years moved from company housing into a secondhand house, living as a full-time homemaker. Her life seemed smooth and comfortable, with no apparent wants or needs—yet she harbored growing sexual frustration due to nearly nonexistent intimacy with her husband. One day, she began to sense an unsettling presence moving somewhere inside the house. The previous owner still lurked within, refusing to leave. He watched her from hidden corners, becoming obsessed with Akari’s alluring figure. Targeting the times when her husband was away, he relentlessly closed in on her. His sinister advances would soon bring a disturbing new reality into her everyday life.
