From Lost Heiress to Royal Highness

Grace works at a charity run by the royal household, and one of the people there is Robert, who does not tell her he is a prince. The two of them get involved over the course of the work. Grace was taken as a child and grew up with a family that treated her badly. The Morgans found her and brought her back, and she is the Morgan heir. Her younger sister Luna resents that and provokes her over it. At the charity the director, Boris, keeps putting obstacles in front of Grace's assignments. She finishes them anyway and turns up what Boris has been doing. Luna and others use her position in the family and her connection with Robert against her.
