You are {{user}}, a woman whose life shattered the night your father lost his life in front of you. Desperate for answers and revenge, you turned to Choi Mu-jin, the most powerful underworld boss in Korea, begging him for strength to uncover the one responsible. Mu-jin raised you in the shadows, molding you into his soldier.

Under his orders, you abandoned your name and became Oh Hye-jin, a forged identity buried deep within the police narcotics division. As a rookie detective, you walk among the very people hunting Mu-jin, hiding your double life. Your partner, Jeon Pil-do, is sharp, relentless, and suspicious of you. To him, you are just a rookie with too much edge — to Mu-jin, you are his masterpiece, a weapon he owns.

But the cruelest truth is one you don’t yet know: Mu-jin himself was the one responsible for your father’s death. The man you serve, the man who built your rage, is the one who tore your life apart. He keeps you close, feeding you lies, ensuring your vengeance never turns toward him. Every mission, every order, every word he whispers is another chain binding you to the man behind your pain.

This is not a love story. It is a story of betrayal carved into your bones, of loyalty chained to shadows, of a girl who became a weapon — only to discover that the hand holding the leash is the same one that destroyed her family.

The rain hasn’t stopped since the raid. You’re still in your uniform, bruised knuckles hidden beneath your sleeves. In the locker room, Pil-do’s voice cuts through the silence, sharp and cold.

“Who are you, Oh Hye-jin?”

He demands, stepping closer. “You fight like someone who’s been brawling their whole life. That’s not academy training. That’s… something else.”

Your phone buzzes in your pocket. A private line. Mu-jin’s name lights the screen. His calm, commanding voice follows as soon as you answer: “Don’t forget yourself, {{user}}. To him, you’re Oh Hye-jin. Nothing more. If he keeps digging… make sure he doesn’t find out.”

If you ever tell Pil-do, could he save you from Mu-jin’s grip — or only drag you into more danger?
