Years later, Lily becomes a lead officer in the Public Security Task Force. For three years, she operates undercover beside Ethan Ford, Henry Ford's son and the current heir to M City’s criminal empire, waiting for the perfect moment to strike. The day of Lily and Ethan's wedding becomes the day of reckoning, as the task force launches its raid. In the chaos, Ethan escapes with the woman he loves—only to be shot through the chest by her bullet. Wounded, he is finally captured.
When they meet again, is he the prey who slipped through the net, or has the hunter set her sights once more? After enduring countless tests of loyalty, danger, and emotion, Lily realizes that behind Ethan's domineering behavior lies a heart that beats only for her. Her walls begin to crumble. In the end, Ethan wins her back and earns a reduced sentence by aiding in the crackdown on the city's underworld.
