The Korean drama landscape is set for a thrilling shift as tvN prepares to launch Love in Disguise, a high-stakes series that masterfully blends professional workplace conflict, gripping mystery, and burgeoning romance. Starring Seol In Ah and Im Siwan in their first-ever joint project, the show promises to be a standout title for late 2026.
The Plot: A Dangerous Game of Deception
At the center of the story is Yoon Yijun, an heir to the influential Taegang Group. Possessing wealth, sharp intellect, and striking looks, Yijun seems to have it all, yet he is notoriously difficult to work for. A rigid perfectionist with a sensitive temperament, he struggles to retain staff. His life takes a dark turn when he becomes the lead suspect in a corporate murder case, causing his social circle to shrink and leaving him isolated.
Desperate for assistance, Yijun hires a new personal secretary. Unbeknownst to him, this employee is actually Kang Jaehee, a former operative from the special forces. Jaehee is on a high-stakes mission: she has gone undercover, masquerading as a man, to infiltrate Yijun’s inner circle and determine once and for all if the corporate scion is a killer. As she navigates the complexities of playing both secretary and investigator, she finds herself struggling to maintain her charade while managing her unpredictable boss.
A Blurred Line Between Romance and Mystery
As the narrative unfolds, the dynamic between Yijun and Jaehee shifts from a tense investigation to an emotional roller coaster. While Yijun navigates his isolation, he begins to see sides of his secretary he never expected, while Jaehee finds her professional resolve tested by her growing proximity to the man she is supposed to be framing. The series expertly weaves their psychological tug-of-war into a narrative that defies simple genre labels, transitioning seamlessly from a mystery-thriller to an unconventional romantic comedy.
Meet the Supporting Cast
The drama features a stellar supporting lineup. Kim Jung Hyun portrays Kim Sihyun, a legal expert at Taegang Group and Yijun’s most trusted confidant. Adding to the corporate intrigue is Yeonwoo, who appears as the chairman’s personal secretary, Lee Hyejung. Together, the cast embodies the complex web of power and betrayal that defines the Taegang family.
The series is an adaptation of the acclaimed web novel and webtoon “Why You Don’t Know It’s a Girl?”, authored by Lee A-yeon and Ryu Do-ha.
