The spoiled wealthy daughter Shen Yuanyuan, due to her impulsive personality, is sent by her mother to Beishan Village to follow Zhou Guizhi and experience cattle-raising and farm work. From struggling to adapt to hard days in the country and disliking farm chores to moving forage, carrying water, and milking cows, she sheds her spoiled attitude through hard labor and learns to respect labor. She learns of the entanglements between Zhou Guizhi and her daughter Zhou Xiaomei, and witnesses the truth of the other party stealing a formula and refusing to acknowledge kinship. After returning to the city, Shen Yuanyuan lets go of her eldest-miss identity, studies dairy-related business in depth, and returns to the countryside to spearhead the establishment of a milk source cooperative, helping villagers solve fresh milk sales difficulties, completing her self-growth, and accepting her imperfect self.
