Aki, the best friend of my wife Mika, was a woman who retained her married woman charm while exuding a subtly seductive allure. Remaining composed and mature, she would occasionally take refuge at our home during marital disputes with her husband. One day, when my wife returned from work, she found Aki acting strangely inside the room. The moment she witnessed the scene, her heart trembled—Aki appeared as if she were offering herself entirely to her. From that day on, she took the step of installing hidden cameras throughout the house. While a man exists within the story's framework, his voice and naked body never appear.
