When her parents died suddenly, 26-year-old jewelry designer Xu Mingshu signed a three-year marriage agreement with the Lu family's heir in order to save the family business. Everyone gets what they need, prices are clearly marked, and even dignity is written into the terms. It was also that year that a man with an overly handsome resume applied for a job as her special assistant.
