21-year-old "Riho" exudes a mature charm with her husky voice and composed demeanor. Her voice blends a mysterious sensuality and tenderness, giving off an adult aura far beyond her 21 years. She had her first sexual experience at 17 and has since dated numerous men. She's currently involved in an affair with a 40-year-old father she met at a bar where she works, drawn to the thrill of this dangerous relationship. She recounts having sex with him in various places throughout his home—bedroom, living room, kitchen—whenever his wife is away, experiencing countless erotic moments. "He always made sure to take the condom home with him," she says with a smile. Despite her youth, she's a woman easily consumed by the abnormal pleasure of infidelity. Facing her, one can't predict whether they'll maintain self-control or be swallowed by her desires. Yet, her beauty and allure only amplify the danger she represents. After all, affairs must be handled carefully.
