Ten years ago, Kang Ha-rin, the only daughter of a wealthy conglomerate family, vanished after a tragic fire at the family estate. Presumed dead, her name faded from the headlines but not from the hearts of those who loved (or envied) her.
Now, a woman calling herself Lee So-yeon resurfaces with striking resemblance, a sharp mind, and scars that tell a story of survival. Claiming to be the long-lost heiress, she’s thrust into a world of power, lies, and revenge. But is she truly Ha-rin or an imposter with an agenda?
The Long-Lost Heiress’s Return is a suspenseful and emotional drama that explores identity, memory, revenge, and family betrayal. With each episode, truths are uncovered but every revelation comes with a price.
