Overworked office worker Lu Youyou accidentally transmigrates into a novel she once criticized, becoming a rabbit spirit who plays the devoted wife for three years in exchange for a one-billion-dollar divorce settlement. Unexpectedly, Qin Du, the CEO, overhears her true thoughts, and the divorce agreement is immediately revoked. As they navigate their complicated life together, Lu Youyou keeps growing rabbit ears whenever she loses control of her emotions, while Qin Du is a hardcore lover of all things fluffy. Just as Su Ling, his idealized first love, returns with a fortune-bringing pearl to scheme against them, Shen Yunci begins plotting to capture the rabbit spirit. Facing one crisis after another, the two finally confess their feelings, expose every conspiracy, and find happiness together.
