She was brought back into the family from an orphanage, only to fall ill with leukemia. The adopted daughter, desperate to hold on to her place in the household, faked the same illness to win everyone's sympathy — and the girl's own brother and mother all turned on her, refusing to believe she was truly sick.
Her heart turned cold. She decided to donate her own body, choosing that way to show her family, once and for all, which of them really had leukemia. At the dissection, when the family saw her remains, every one of them was consumed with regret — for the body showed no trace of the disease; she had already been cured.
Having faked her death, she returned from abroad and began her campaign of revenge. In the end she tore off the adopted daughter's mask of innocence — and though her family regretted everything, it was far too late.
