Love in Disguise has become one of the most talked-about K-dramas of late 2026, and the reason is simple: it mixes a murder mystery, a gender-bending undercover mission, and a slow-burn romance into one addictive story. Starring Yim Si Wan and Seol In Ah, the tvN series premiered on October 19, 2026, and streams globally on Prime Video in more than 240 countries and territories.
The show follows Yoon Yi Jun, a third-generation chaebol heir who becomes the prime suspect in a murder case, and Kang Jae Hee, a former special forces officer turned detective who disguises herself as a man to work as his personal secretary and investigate him from the inside. By Episode 8, which aired on November 10, 2026, the story takes a sharp turn when a public moment between the two leads to an unexpected “bromance” scandal that threatens Yi Jun’s position at his family’s company.
What Is Love in Disguise About?
The series is based on the hit web novel “Why Don’t You Know It’s a Girl?”, which has accumulated over 8.15 million views. The story begins with a shocking death: Han Eun Young (played by Jung Yoo Min), Yoon Yi Jun’s secretary, is found strangled with a belt inside his office.
Yi Jun is the managing director of Taekang Group’s Task Force and the heir apparent to the company. His father, Chairman Yoon Tae Sik (Choi Jin Ho), is preparing to finalize the succession process and has one instruction for his son: stay out of trouble . But the murder case puts everything at risk. Yi Jun’s fingerprints are found on the belt, but no skin tissue or blood is discovered on the victim, leaving the evidence incomplete.
Kang Jae Hee is a police detective with a former special forces background. She is often mistaken for a man because of her short hair and tomboyish style, a detail that becomes the key to the undercover mission. Her team is assigned to investigate the murder, but their hands are tied because Yi Jun is protected by Taekang’s legal team and the police leadership refuses to arrest a chaebol heir without solid proof.
Jae Hee proposes going undercover as Yi Jun’s new secretary to find his missing phone, which may hold crucial evidence. The job opening is for men only, but that is not a problem for her. She applies, and despite having zero secretarial experience, she gets the position after a twist of fate: Yi Jun’s outgoing secretary adds her application to the interview pile out of spite.
“He was born into a life where everything he had to do was already decided for him, leaving little room for what he actually wanted,” Yim Si Wan said about his character, Yoon Yi Jun.
Yoon Yi Jun: A Chaebol Heir With No Real Freedom
Yoon Yi Jun is not a typical rich heir. He is arrogant, difficult, and demanding. He throws stacks of reports in the air when they do not meet his standards and refuses to drink tea if the temperature or brewing time is off by a single degree. But underneath that harsh exterior, he is a man trapped by his family’s expectations.
Yim Si Wan described Yi Jun as someone whose privileged upbringing left him with little control over his own life. The actor said he wanted to present a different kind of chaebol character, one who is not simply powerful but also deeply constrained. Yi Jun is left-handed, a small detail that becomes important in the murder investigation because the suspect is believed to be left-handed or ambidextrous.
His relationship with his secretary, Han Eun Young, is ambiguous. The show does not clearly state whether they were romantically involved, but Yi Jun was trying to end whatever arrangement existed between them before the succession process was finalized. Han refused and threatened to go to the chairman, setting the stage for her murder.
Kang Jae Hee: A Detective Who Blurs the Line Between Duty and Desire
Kang Jae Hee is a force of nature. As a former special forces officer, she is trained in multiple martial arts, including judo level five, hapkido level one, and taekwondo level three. She has a strong sense of justice and a fierce competitive streak that makes her a formidable detective.
Her undercover mission requires her to pretend to be a man, which she does with surprising ease. The disguise works so well that Yi Jun himself does not realize his new secretary is a woman. Their dynamic becomes the heart of the show: she is secretly investigating him while he is being difficult and demanding, and neither can deny the growing tension between them.
Seol In Ah described Jae Hee as more than just a woman in male disguise. “Jae-hee is not just a woman in male disguise, but also someone who has a special forces background,” she said, highlighting the character’s physical strength and emotional complexity.
The Supporting Cast: Lawyers, Secretaries, and a Fiancée
The drama features a strong supporting cast whose stories are woven into the main plot.
Kim Jung Hyun plays Kim Si Hyun, a lawyer on Taekang Group’s legal team and Yi Jun’s close friend. Living by a motto of “moderation” and “cost-effectiveness,” Si Hyun is a sly man who takes good care of his boss while hiding his true feelings. His life changes when he meets a woman who awakens his hidden competitive drive.
Yeonwoo plays Lee Hye Jung, the secretary to the Taekang Group chairman. She is known for her striking beauty, strong abilities, and cautious personality. At work, she is the model of a perfect secretary, but after hours, she follows an “enjoy my life” philosophy, revealing a surprising duality.
Choi Hee Jin appears as Lee Si Ah, Yi Jun’s fiancée. Her sudden arrival in Episode 5 catches both Yi Jun and Jae Hee off guard. What makes the situation even more confusing is that Jae Hee had no idea Yi Jun was engaged, despite working closely with him. Lee Si Ah also shows unusual interest in Jae Hee, boldly asking for her contact information during their first meeting, which hints at a tangled dynamic among the three characters.
The Scandal That Changes Everything
The central event of the recent episodes is the “bromance” scandal that erupts in Episode 8. During an official event, Jae Hee is nearly hit by a motorcycle. Yi Jun rushes to save her and pulls her tightly into his arms. This moment becomes public, and the two are caught up in an untimely scandal.
Yi Jun faces criticism for unilaterally leaving an important official event to save Jae Hee, which causes disruptions to the proceedings. The preview for the episode shows Yi Jun’s search results suddenly filling up with the word “bromance,” turning the entire company upside down.
The situation becomes even more serious because Yi Jun is urgently summoned to the office of his father, Chairman Yoon Tae Sik. The chairman is known for his strict standards and does not tolerate even the smallest flaw in his successor, so all eyes are on how Yi Jun will get through this crisis .
What makes the scandal particularly ironic is that Yi Jun has only just begun to acknowledge his feelings for Jae Hee. In the episodes leading up to the scandal, he had been in denial about his emotions, refusing to admit what he felt after an accidental lip collision and a second kiss. The possibility of losing Jae Hee—when his fiancée, Lee Si Ah, attempts to recruit Jae Hee as her own secretary—becomes the wake-up call he needs.
“Yoon Yi Jun reveals a sweet and affectionate side that is completely different from the way he has behaved as a chaebol heir and boss until now,” a Soompi report noted about his changed behavior, describing how he gazes affectionately at Jae Hee, offers her his health juice, and reserves a romantic restaurant to pursue her.
The Murder Mystery: Clues, Suspicion, and Hidden Truths
The murder of secretary Han Eun Young remains the driving force of the plot. The investigation reveals several key details:
- Yi Jun’s fingerprints are on the belt used to strangle Han, but no skin tissue or blood is found on her body, which is unusual given the signs of struggle.
- The suspect is believed to be left-handed or ambidextrous, and Yi Jun is left-handed.
- Han’s phone is missing, and its last known location was near Yi Jun’s office. Jae Hee believes the phone contains crucial evidence.
- An anonymous tip provides a video of Yi Jun threatening Han, which deepens suspicion against him.
The police leadership is reluctant to pursue Yi Jun aggressively because of Taekang Group’s power and influence. Captain Park Bong Yi and her team are instructed to conclude the case as a circumstantial suicide, but Jae Hee refuses to let it go.

What Makes the Show Work
The chemistry between Yim Si Wan and Seol In Ah is the backbone of the series. A Mashable review praised their banter and comedic timing, noting that “their chemistry is just chef’s kiss” and that the show delivers “more funny moments than tense ones” in its early episodes.
The gender-bending premise adds a layer of tension that keeps viewers guessing. Yi Jun does not know that his male secretary is actually a woman, and Jae Hee does not know that Yi Jun is beginning to develop feelings for her. The show plays with the blurred line between “bromance” and romance, and the scandal in Episode 8 forces that tension into the open.
