Gwen was about to lose her restaurant, a venture she had started with her friend. Gwen was the head chef and the restaurant was doing well, until the day her friend suddenly took off. Still unsure what to do, she meets Count Etienne Moreau. He saves her from a group of drunkards, and then they share a night of passion together. She feels blessedly happy until he tells her the next morning that he'll support her financially if she'll agree to be his mistress... What kind of a restaurateur does he think she is?
