Recently moved and still adjusting, the Miyamura couple face new challenges. Due to his job in sales, her husband is frequently away on business trips, leaving Nanako emotionally vulnerable—especially after being told she needs a follow-up cancer screening at work. As she struggles to adapt to her new environment, she becomes increasingly sensitive to small, everyday occurrences. One day, she learns that her husband's underwear, which she had hung out to dry, fell into the neighbor's yard. An older neighbor, a middle-aged man from next door, comes to return it. He instantly falls for Nanako's beautiful legs and develops a strong attraction. But his true motive is darker—he's a peeping pervert who has already been secretly watching her. Though uneasy and alone, Nanako politely asks him to be friendly, hoping to build a good rapport. When later her own panties end up in his yard, he mistakenly believes she's flirting with him, sparking his uncontrollable lust. Right outside her home's front entrance, while her husband is inside and she's hanging laundry, her prized assets—her long, gorgeous legs, her perfect breasts, and her big, shapely ass—are exposed and repeatedly violated by the old man's perverted advances.
