The entire drama is a modern American wealthy-family cute-baby pampering light comedy. Its core highlights are a three-and-a-half-year-old cute baby claiming her family, a cold wealthy father's "true love" turnaround, six brothers competing to spoil their little sister, the daily contrast between father and daughter, and the healing of a wealthy family.
The Blackwood family was originally all men, until three-and-a-half-year-old Lily Blackwood suddenly appeared, throwing this cold wealthy family into complete chaos. On a stormy night, three-and-a-half-year-old Lily arrived alone at the Blackwood estate, hugged Damian Blackwood's leg, called him "Daddy" in a soft baby voice, and publicly mentioned that night three years ago at the Grand Regent Hotel, telling Damian she was his biological daughter. The cold and powerful Damian did not believe it at all, and even threatened that if the DNA proved she was truly his daughter, he would bury her together with the "mistake" from three years ago. Yet while his mouth said he would throw Lily out, his body was repeatedly more honest than his words—when she acted cute, he held her in his arms; when she was hungry, he personally fed her milk; when she was sleepy, he covered her with a blanket; he even began secretly smelling the milky scent on her. This wealthy family patriarch, who had never known how to care for children, gradually became a completely tough-mouthed but soft-hearted daughter slave in front of Lily.
