The Billionaire's Substitute Bride

Sophia is forced by her adoptive mother to replace a runaway sister and marry Damien, a wheelchair-bound billionaire believed to have less than a year to live. She discovers that she is the savior he has searched for over ten years and uses her concealed medical genius to stop repeated plots and investigate her parents' deaths. When Damien's uncle Victor poisons him, Sophia reveals her identity to save his life. They take revenge together; Damien later falls protecting her and Sophia gives birth prematurely, before the family of three reunites after surviving the crisis.
