Yuna, daughter of the kingdom's largest merchant guild (the Sharon Trading Company) with noble earl blood, is forced into an arranged marriage with Jude, son of the Quentin Trading Company, after her father loses a bet. Though initially worried, Yuna warms up to Jude because he is handsome and soft-spoken. However, Jude hides a toxic trait: he puts his female childhood friend, Baroness Aria, above Yuna in every single situation. After endless last-minute canceled dates, rude demands from Aria, and Jude's self-centered entitlement, Yuna reaches her limit. Resolving to break off the engagement, she sets her revenge in motion, joining forces with a mysterious, sharp-witted handsome noble who knows her past to bring down her trashy ex-fiancé once and for all.
