When Ava and Ethan meet again at a hotel three years after their breakup, old wounds erupt fast. Ethan believes she chose his half-brother Lucas over him during his darkest days, when illness and inheritance troubles nearly broke him, and he puts her through public humiliation. Yet the reality was far more painful: Ava had quietly donated a kidney to save him, then arranged for Lucas to fake her betrayal so she could go abroad for treatment. Once Ethan uncovers the truth, he heads to Switzerland to face her, apologizes, and pleads for another chance before her second surgery. Their long-buried misunderstanding finally comes to light.
