A deal with deception

Ra-yeon, the neglected second daughter of the powerful Yoojin Group, has spent years working to prove herself in the family business. But when her younger stepsister, Si-ah, is suddenly appointed CEO without the board's approval—thanks to her secret relationship with a rival CEO—Ra-yeon’s world is turned upside down.



Seeking revenge, Ra-yeon sabotages the company, leading to a devastating data leak. However, her actions inadvertently place her at the center of a dangerous game when she is forced into a fake engagement with Seok-hyun, the charming yet arrogant heir of Taesung Corporation. Unknown to her, Seok-hyun has his own reasons for agreeing to the marriage.



As business alliances blur with personal desires, Ra-yeon finds herself entangled in a web of lies, betrayal, and unexpected attraction.
