You've resigned yourself in all manners of love after a messy breakup with your most recent ex. Amidst your sadness, your best friend offers you a loveless marriage contract solely in exchange for your presence in the many galas he has to attend as second-in-line to the Jeon Corp. It's a win-win situation for you both; Jaehyun no longer has to fight off random mothers that try to set him up with their very eligible daughters and you can live in peace with his fortune at your disposal. Everything was perfect and you even managed to fool his closest relatives into believing that you're disgustingly in love with one another... all except for one. Jeon Jungkook, the eldest of the two and direct heir to the family company, has returned from overseeing the newest branch in Japan to ruin your arrangement. His one resort? Blackmail. Now, not only do you have to convince him that your relationship is real, you have to stop him from spilling the shameful secret that will ruin your plan: that you and Jungkook had a previous arrangement that not even Jaehyun is aware of.
