Waking up overnight, a working woman unexpectedly became a deeply despised princess, and still had to raise a three-year-old son. Learning that the future of mother and son was fraught with crises, she used a beauty and child-raising system to accumulate points, managing her weight and raising her child on one hand, while reclaiming the initiative on the other. Facing her mother-in-law's harassment and backyard scheming, she audited accounts and set rules, decentralized household management, turned the estate's regular meetings into workplace meetings, raised funds to open a self-service lifestyle store, and even dragged the reclusive prince to cut the ribbon. The prince originally suspected her of having ulterior motives, but was gradually attracted by her changes and capabilities. While she was busy protecting her child and making money, he went from cold detachment to growing care, and a relationship full of rivalry quietly gave birth to true feelings.
