Cruel step-relatives force quiet orphan Ivy to scrub marble staircases on her knees, mocking her as a worthless stray who relies on their charity for scraps. Having lost her mother at the age of two, Ivy endured a decade of street poverty before bravely pulling young heir Lucas from a burning vehicle. Despite Lucas's fierce loyalty, his snobbish family treats Ivy like an embarrassment, plotting to frame her for jewel theft during the grandfather's birthday banquet. But the scheme backfires spectacularly when international elder patriarchs arrive with sealed ancestral registries. Ivy is revealed as the sole surviving direct heiress of the nation's founding financial clan, holding the legal deeds to the very estate where she was abused. As Lucas stands by her side, the arrogant relatives scramble in terror, begging for forgiveness before the royal guard. Will Ivy show mercy to the relatives who despised her, or take back everything?
