Three-star master chef Su Wan time-travels to become an ancient peasant girl. With a barren home and a malnourished family that treasures her like a precious gem, she uses her culinary skills to set up a stall selling roujiamo, making a fortune every day to support her eldest brother's studies for the imperial examinations. Picking up a heavily injured and amnesiac noble young master, A Jiu, from the mountain, he becomes her loyal, cold-faced watchdog guarding her closely. When rivals pick a fight and gossiping shrews wag their tongues, the whole family steps up together. The little female chef makes a fortune and gets a young marquis as a husband along the way.
