Three-year-old sweet tot Yuyou is a little old-school stall-owning boss. Having grown up living with her mom, she is unexpectedly welcomed back into the wealthy family by her cold and aloof president dad, Shen Yuebai. The soft and fluffy darling is quirky and clever, insisting on going out to set up stalls to build her career, and wrapping her president dad around her finger into a bona fide daughter slave. Heartwarming and sensible, she reaps the full affection of her grandfather, uncles, and brothers in the Shen family, staging one hilarious and healing everyday moment after another of a cute toddler.
