The quirky five-year-old Huohuo transmigrates into the body of Yu Huohuo, a girl with the same name whose mother has just died. Carrying the black wooden hairpin her mother gave her as a keepsake before she died, and with help from some little animals, she finds the Third Prince, Prince An, Yu Linchuan, in the capital, where he has been looking for a way to die, and claims him as her father. Through a series of misunderstandings, they embark on a chaotic and hilarious tale of a “loving” father and a “dutiful” daughter. She “tricks” her dad while protecting the kingdom, and stirs up the “rats” in the imperial palace until they're all in a panic!
