Wen Ruan wakes up to find she has transmigrated into a rushed-ending novel, becoming a little female tiger. The villain in the book, Ao Lie, is her biological father—an ultimate simp who is treated as a backup by his white moonlight, used as a stepping stone by the crown prince, and always ready to commit suicide by drinking out of despair. Without missing a beat, Wen Ruan storms the Prince of Yu's Mansion to claim kinship, kicking off a chaotic daily routine of "guiding her father to counterattack." From father and daughter chasing each other with feathered dusters to standing shoulder to shoulder against the open and hidden arrows of the entire court, a grand drama of reverse parenting is now staging.
