Before I Knew It, I Was the Hottest One in the Village

(A laid-back farming story. If it's not your thing, please don't flame it.) A young doctor from the modern era accidentally transmigrates into the body of a little girl from a farming family in ancient times while working a night shift. She also gains a shop System. From then on, she becomes the family's most adorable little darling, makes life at home more comfortable, and leads the villagers toward a prosperous and harmonious life amid green hills and flowing streams, peaceful and carefree.
