Yu Xiyue awakens to the realization that she is the vicious supporting actress in a novel. To escape being controlled by the plot and the fate of her family's ruin, she deliberately returns home "pregnant," setting her sights on the nation's top actor, Feng Jingche, to be the child's father—a contractual marriage solely for the sake of bringing good luck. Unexpectedly, after the wedding, the actor's "morning sickness" trends on social media for her sake, and what began as a contract marriage turns into real love. Armed with memories of her past life and her wits, Yu Xiyue tears through the plot's obstacles while safeguarding her family's wealth, making the Yu family prosper more and more. As her childhood sweetheart Gu Feiran clings persistently, and as the stand-in An Wanwan's fate takes a dramatic turn, she and her actor husband join hands to rewrite the ending—ultimately defying fate, becoming a winner in life, and reaping double happiness.
