She is constantly framed and sabotaged by Sarah, Victor's idealized first love, and soon uncovers the hidden truth behind that year's car accident. After an explosion, Eileen fakes her death, transforms herself, and returns with a new identity to seek revenge, systematically dismantling Victor's business empire. After enduring numerous life-and-death trials, the two resolve their many misunderstandings, let go of their past love and hatred, and move towards reconciliation and a life together.
