Ethan Cole, chairman of Meridian Group and a world champion racing driver, grows weary of the sycophancy around him. To find someone who would treat him sincerely without knowing his wealth, he disguises himself as a beggar on the street. Lucy Bennett, a kind designer unaware of his identity, gives him a hundred dollars for a meal. Meanwhile, Lucy is pressured by her mother to bring a boyfriend home for her fiftieth birthday. On a whim, she "rents" Ethan as her fake boyfriend for seven days at two hundred dollars a day. Ethan follows Lucy back to Willow Creek, playing the role of a broke nobody in front of her family, but cannot resist stepping in to save the town from a collapsing orange market—building a brand, running livestreams, fixing trucks, and managing logistics to get Willow Creek mandarins sold across the country. Over seven days, the two grow close. When the contract expires, Meridian Group arrives at the county for an industrial partnership conference, and Ethan takes the stage as the chairman himself. Lucy is shocked to discover the "boyfriend" she rented is actually a billionaire. The status gap makes Lucy retreat out of insecurity, but Ethan, holding onto that hundred-dollar bill he kept all this time, confesses his love in the sunset orange grove. What started as a seven-day rental becomes a lifetime contract.
