A modern actuary wakes up in the body of a rural girl whose engagement has just been broken off. Her father's old debts, her aunt's embezzlement, and the clan elders' disdain are all things she sees clearly. Neither crying nor making a fuss, she has one goal: settle every account, one by one, and build a name for herself. Sharp-tongued but soft-hearted, she can balance the books of three households, yet still leaves a way out for those who have nowhere else to turn.
