Dressed as a "fake daughter", Su Nian'an is gentle and cute but has a tough heart. She accidentally breaks into the world of the indifferent CEO Fu Chenyuan, and has been held in the palm of his hand and protected behind him ever since. From the jealousy of being picked up forcibly while drunk at the bar, to the warm daily life of exclusive feeding in the office, from the shyness and apprehension when meeting parents, to the persistence when an old illness breaks out, the love between the two heats up through heart-pounding interactions, and becomes stronger as they protect each other.
