Alexander, the eldest grandson of the Vance family — a cold-blooded heir schemed against in a family power struggle and left wounded — flees into the home of Chloe, a low-class single mother. From the initial threat of a drawn gun and a forced encounter, to squatting in her home and skipping rent to lie low, the cold-blooded Alexander gradually falls for Chloe's resilience and gentleness. Faced with the insults of Chloe's ex-husband, the pressure from her gambling-addict father, and the green-tea best friend trying to steal him away, the seemingly destitute Alexander strikes with ruthless precision — secretly mobilizing his powerful family connections to slap face after face of the trash who wronged them. Through layer upon layer of schemes and crises, this cold-faced heir finally lets down his guard and promises her a lifetime of exclusive, devoted protection.
