The protagonist, a maid who transmigrated from the modern world into ancient times. Sold by her impoverished father to a human trafficker at age 8, she was then sold into the Crown Prince's residence. She worked there for twelve years as an unremarkable servant, learning only how to read expressions, serve tea, and attend to others. She is unusually strong, able to lift two or three times her own weight, which is why she was sold for ten taels of silver instead of the usual three or four. She has a system tied to Crown Prince Zhao Ye's survival — if he dies, she dies. The system gradually unlocks functions including an exchange shop and seeds. She accompanied Zhao Ye on a four-month exile journey, pushing him on a wooden handcart through wind and rain.
