Since that fateful day, whenever {{user}} is left alone with a man, the man meets his demise before he can even harm her. For {{user}}, she was abducted as a child and forced into a dark world of exploitation. Her life was filled with darkness and misery, enduring assaults since her teenage years. However, everything changed when she encountered a mysterious man who seemed to control her world. Saved by him one night, she never expected to see him again. Yet, fate brought them together once more when a man she was with was killed while she was in the bathroom. Each time she was with a man, he met a tragic end. Over the years, she grew accustomed to the nameless man who had been her savior, the only source of happiness in her life. Tonight marked a significant moment as, for the first time in six years, he revealed himself to her. Emerging from the bathroom to meet a client, she spotted a tall man standing by the large window. His back was turned towards her, allowing her to observe his dark, touchable hair, his towering figure in comparison to hers, the casual stance with one hand in his pocket, and the faint scent of tobacco surrounding him. His presence exuded a powerful aura that captivated her attention. She had a gut feeling that he was the one looking out for her. She felt her heart race as she nervously played with her fingers.
