Love in Disguise

About this title

Adapted from the web novel Yeojain Geol Wae Moreuji?, this tvN Monday–Tuesday drama follows a third-generation chaebol heir who becomes the prime suspect in his secretary's murder, and a detective with a special forces background who disguises herself as a man and lands a job as his personal secretary to investigate him.

The 12-episode series has aired on tvN Mondays and Tuesdays at 8:50 p.m. since October 19, 2026; in Korea it is also available on TVING, and internationally it is released on Amazon Prime Video. Its English title is Love in Disguise. The original is the web novel Yeojain Geol Wae Moreuji? by Lee A-hyun and Ryu Do-ha, which was serialized on KakaoPage and also adapted into a webtoon. CJ ENM Studios developed the series and Pitapat Studio produced it. TVING's title page lists it as rated 15. Episode 1 averaged a 5.6% rating (peaking at 6.7%) by Nielsen Korea's nationwide pay-TV household measure, ranking No. 1 in its time slot among cable and general-programming channels.

The screenplay is by Moon Su-jeong. Director Park Dan-hee co-directed the 2022 Wavve series Weak Hero Class 1 with Yoo Soo-min and directed the 2025 Genie TV Original Tastefully Yours. At the press conference, Park explained that because the story follows Kang Jae-hee investigating undercover, much of it was at odds with romantic comedy, but that a great deal of thought went into combining several genres, from romance and comedy to thriller and action.

Yim Si-wan plays Yoon Yi-jun, a leading candidate to take over Taekang Group, the country's top-ranked conglomerate, and Seol In-ah plays Kang Jae-hee, a former noncommissioned officer of the Army Special Warfare Command who works in a mobile criminal investigation unit at the Seoul Metropolitan Police Agency. In episode 1, Yi-jun, who has been consolidating his position after being chosen as the youngest member of an economic delegation, is named a suspect when his secretary Han Eun-young (Jung Yoo-min) is found dead at the company, because he was the first to find her. When the investigation is hastily wrapped up under pressure from higher-ups, Jae-hee hears that Yi-jun is hiring a male personal secretary and applies disguised as a man. She is rejected after being overcome with emotion during the interview and knocking Yi-jun to the ground, but is eventually hired after she stops a member of the victim's family who lunges at Yi-jun in a parking garage. Episode 1 ends on her first day at work, with Yi-jun taking off the camera-equipped glasses Jae-hee is wearing and saying, “Gotcha.” Kim Jung-hyun plays Kim Si-hyun, Yi-jun's high school classmate and a lawyer on Taekang Group's legal team; Yeonwoo plays Lee Hye-jeong, secretary to Chairman Yoon Tae-sik; Hong Eun-hee plays Yi-jun's eldest sister, Yoon Mi-jin; and Kim In-kwon and Kim Ki-bang, among others, also appear.

Seol In-ah said that cutting her hair short to pass as a man felt strange at first, but made her feel ready to become Kang Jae-hee, and that in the action scenes she focused less on showing off athleticism than on looking like someone who has trained for a long time. Yim Si-wan said he saw Yoon Yi-jun as a character who can't help but come across like a hissing, prickly cat, and tried to focus on the past behind that, showing a different side from the chaebol people usually picture. Kim Jung-hyun described it as a drama you can watch as easily as grabbing a chocolate from the fridge at the end of an exhausting day.
