The apartment manager installs hidden cameras in residents' homes to secretly monitor young housewives. This time, 25-year-old Yuri Na, married for three years, becomes his target. With her husband busy at work, she's left sexually frustrated, making her vulnerable to the manager's advances. Posing as coincidence, he seizes opportunities to meet her. He sneaks cameras into her home, spying on her bath. After showering, she drinks alone and touches her husband's cock to seduce him, but gets rejected. During the day, while her husband is away, she can't resist masturbating—when suddenly the doorbell rings. Opening it, she finds the manager, who knows exactly what she likes. He kisses her deeply; she says "No," but smiles and doesn't resist, leading to intense sex in the living room.
