Marina gave up the Chaves family fortune to secretly pursue a five-year romance with Leonardo Flores, the powerful tycoon for whom she sacrificed everything. But when he accepts an arranged engagement to heiress Lorena Camargo, Marina is treated as a disposable mistress, humiliated in front of the elite, and forced to end their relationship. What Leonardo never imagined is that his quiet secretary was no ordinary woman: she is the true heir of the Lux Group — and is carrying his child. Now, the woman he scorned can return as the owner of the empire everyone was desperate to seize.
