Mo Xiujin is Mo Xiufang's third and youngest sister. She is hardworking and skilled at cooking, though she never bothered to cook at home before. She offered to work as a live-in housekeeper for free at Jiang Xiaoci's grandmother's house for one year in exchange for learning how to make steamed buns. Her goal is to set up a breakfast stall and sell breakfast together with Xiufang to support her sister, who will be busy caring for her mother-in-law after marriage. She is described as a good girl who wants to repay her sister's two years of worry.
