Lady Gina, the daughter of the Duke, is particularly skilled at cooking. But her fiancé Fincent, the crown prince of the kingdom of Feringa, keeps on belittling her by saying her food is "disgusting" regardless of what she makes. So unable to further tolerate his verbal abuse towards her dishes, she runs away from home, determined to break off her engagement with Fincent. After making a disguise and falsifying her identity, Gina now works in the dining hall of the royal academy. Through happenchance, Prince Schist, the second in the line to the throne, ends up eating her homemade lunch. But contrary to the treatment Lady Gina has experienced up to this point, Schist becomes enamored by her cooking ability and pleads for her to cook meals for him. So, she begins to use her incredible cooking skills to turn the tables on her former fiancé and put him to shame!
