Leora is the long-lost biological daughter of the Taylor family. After being taken back to their wealthy home, she ends up living in a doghouse next to the villa, suffering from asthma and left unattended. She is also constantly framed by her adopted daughter, Lilith. In her past life, she uncovered Lilith and her bodyguard, Raoul's, plot to harm the Taylor family, but was misunderstood and driven out by the entire family, ultimately dying tragically. Reborn, Leora no longer tries to please them, publicly retaliating, severing ties, and returning to the William family who truly loved her. She wins a biotechnology championship with her model of a rare childhood lung immune disease, becoming a rising star in medicine. Her three brothers gradually discover that she once loved and saved them, only to be deeply hurt by them. Leora now stands under the lights of the William family's house, never looking back.
