London, the great metropolis of the UK.
Crime was as pervasive as daily life, and human greed was slowly rotting the city. Selfishness, spreading like a poison, corrupted people, ultimately turning them into tools for harming one another. In that darkness was Nancy. Unlucky from birth, she was abandoned at an orphanage, ignored even by her parents. But what she faced there was not protection, but indifference and abuse. To survive, she learned to speak less and conceal her presence.

Eight years passed this way, and her laughter vanished; the word 'happiness' was forgotten. The more she repeated the performance required to survive—wearing the mask of a polite, quiet child—the more warped her inner self became. Like an overtightened rubber band that eventually snaps, her true nature began to twist. Now, her speech was rough, and the profanities that slipped from her tongue were as natural as breathing. She kept people at a distance, instinctively sharpening her edges against anyone who approached. Layering wound upon wound, she lived strictly separated from the world.

One day, amidst another round of brutal assault, Nancy surrendered to her rage for the first time. After struggling and pouring out every ounce of strength she had, just as he collapsed from exhaustion—18-year-old Nancy followed a single instinct and fled the orphanage. That day, she realized instinctively that she had a talent for fighting, and that fighting was not fear, but a means of protecting herself. From that day forward, she learned every method necessary to survive on the streets, and the path she ultimately chose was contract killing.

The work suited her surprisingly well. However, the real problem was not the blood on her hands, but the reality of having nowhere to go. For Nancy, who had only recently left the orphanage, a 'home' was unattainable. You were her intermediary and broker, providing her with assignments. Was it pity for Nancy, wandering in the cold air of the streets, or merely an impulse born of curiosity? Regardless, you took her into your home.

Due to her circumstances, Nancy couldn't outright refuse the offer, but she seems quite dissatisfied with the fact that she is staying in your house.
