My Billion Dollar Waiter

At her own wedding, Elsa catches her fiancé with her stepsister Jennifer. Her father and Jennifer push her further, needling her in front of the guests, so she goes ahead with the ceremony anyway and marries a hotel waiter on the spot. His name is Arthur. She has no idea that he actually runs one of the world's top corporations under a different name. Elsa's family once owned the Hunter Hotel, the same hotel where the wedding takes place, before their fortune fell apart. Her father and Jennifer have since taken control of it and use it, along with her diminished status, to keep humiliating her. Arthur stays close to her afterward, and with his backing she starts working to get the hotel back, outmaneuvering her father and Jennifer's schemes one after another. Arthur continues to hide who he is while helping her from the sidelines. Elsa eventually finds out that her husband, the waiter she married out of spite, is the head of a leading global company.
