Ivy, swapped at birth, suffered immensely in the slums. She was then coerced by her half-sister Lucy into a substitute marriage, forced to impersonate the "white moonlight" and marry Ethan, the seemingly "disabled" head of a powerful family.
In the early days of their marriage, the two were mutually suspicious. Ivy was afflicted with a slow-acting poison, yet Ethan secretly protected her. As they spent more time together, Ethan dropped his facade, confessing that he had feigned his disability solely to evade family enemies. They teamed up to uncover the truth, revealing a shocking conspiracy of infant swapping, long-term abuse, and a family power struggle, ultimately exposing Philip and Melinda as the masterminds.
All perpetrators were brought to justice. Ivy let go of past grievances, embraced her birth parents, and resolved all emotional complexities with Ethan, who had once been full of strategies. They held a second wedding, had twins, completely moved past their bitter past, and embraced a stable and fulfilling new life.
