In rainy New York, Sophie, a lawyer from Brooklyn, is desperate for half a million dollars for her mother’s kidney transplant. Alexander, the cold CEO of Hale Group, offers her a one-year fake dating contract. She needs to pretend to be his girlfriend to stop an arranged marriage and will get five million dollars in return. Sophie thinks it is merely a business deal. She never knows that he sets up this whole plan just for the umbrella she gave him casually outside a convenience store on a rainy night seven years ago.
