Lin Xiaoman accidentally walks into the wrong private dining room and mistakes the cold, aloof CEO Gu Yanzhi for a man she is supposed to drive away on a blind date. Unexpectedly, the more outrageous she behaves, the more pleased he becomes, and he even offers her a generous salary to pretend to be his girlfriend. Spending lavishly, slacking off, and talking back to wealthy socialites, she tries every trick in the book to make the Gu family dislike her, only to be spoiled beyond belief instead. But when the truth about their mistaken identities finally comes to light, she discovers that Gu Yanzhi knew the truth all along and never once considered replacing her.
