He thinks his new bodyguard is a man. She is the detective investigating him for murder. Love in Disguise follows Yoon Yi-jun, a third-generation chaebol heir who becomes the prime suspect in a murder at his family’s company and goes into hiding. Assigned to both protect and investigate him, former special forces officer turned detective Kang Jae-hee goes undercover as a man and takes a job inside his inner circle — as his personal secretary / bodyguard. The closer she gets to the truth, the harder it becomes to keep her cover — and her feelings — intact, because Yi-jun starts falling for the person he believes is his male protector. The series premieres October 19, 2026 on tvN in Korea and streams globally on Prime Video, with new episodes every Monday and Tuesday.
