Mr. Ji, See Clearly, I'm Your Bodyguard Season 1

Jeni’s family forces her into an engagement with a stranger. Refusing to be a pawn, she escapes before the wedding, determined to reclaim her freedom. But her defiance turns dangerous—her own family hunts her down, ready to drag her back. To survive, Jeni disguises herself as a man and takes an unexpected job as a bodyguard to a wealthy businessman. She has no idea he’s the same man she was supposed to marry.
