On her eighteenth birthday, Gu Weiwei is told that she is the fake heiress who was switched at birth into a wealthy family. She accepts it calmly and prepares to start working for a living. But one rainy night, a string of candied hawthorns leads a darling little boy to cling to her and call her “Mommy” in his sweet little voice. Then his immensely powerful father appears, and she discovers that the child she casually “kidnapped” is the apple of the eye of the Fu family, the most powerful family in the capital. From then on, not only is she spared being thrown out of the wealthy family, she goes from a supporting character in a true-and-fake heiress story to the heroine of an elite-family romance, cherished by both the Fu heir and a genius little boy.
