Olivia is nineteen and pregnant when a setup orchestrated by her stepsister hands her twin boys and a tycoon named Ethan she barely knows. Her father takes the elder twin, Eli, and abandons him; Olivia flees abroad with the younger, Sunny, and rebuilds herself into a top surgeon under a new name.
Years later she comes home as Iris to find the son she lost. Her stepsister Mia and a greedy lover are circling the family's pharmaceutical assets, and Ethan is the wall between them and the takeover. The twins work out on their own that they share blood, and start nudging their parents back together while Olivia survives kidnapping, a frame-up, and an assassination attempt before she finally pulls out the surgeon's credentials everyone underestimated.
