The secretary’s job is open only to men, and Kang Jae-hee is accustomed to being mistaken for one. For the detective played by Seol In-ah, the vacancy offers access to a murder suspect whom ordinary police work cannot easily reach. Love in Disguise builds its premiere around this useful collision between an employer’s restriction and a woman whose everyday presentation already confuses other people’s expectations. Jae-hee volunteers for the assignment with the practical confidence of someone who has identified an opening in a closed institution.
Her masculine presentation predates the investigation, which gives the disguise a welcome degree of continuity with her life. She needs a false professional identity; she does not need the assignment to supply her physical confidence. A former Special Forces member with martial arts training, she enters the romantic setup carrying skills that serve her own purpose.
Seol’s commitment to the action and slapstick keeps that competence lively rather than ceremonial. Jae-hee can fight, endure embarrassment, and push back against her prospective employer’s demands. The production gives its heroine physical work to perform instead of treating toughness as a character description that the romance can quietly discard.
That arrangement also makes the gender comedy worth watching with some care. Threats to Jae-hee’s cover create understandable comic pressure because exposure would jeopardize an investigation. Mistaken identity can generate laughter without making her ordinary behavior a defect awaiting correction.
The premiere’s setup leaves room for attraction that unsettles easy assumptions about gender, though it would be premature to credit the series with a developed queer perspective. A woman being perceived as male does not establish the sexuality of the man watching her. What the episode offers is a productive uncertainty about how its romantic attention will operate.
The man in question benefits from several kinds of protection. Yoon Yi-jun, played by Yim Si-wan, is Taekang Group’s managing director and a likely successor to its ailing chairman. The opening places him above his unresponsive secretary, Han Eun-young, apparently handling the belt associated with her strangulation.
His DNA places him at the scene. Yet his lawyer friend Kim Si-hyun helps shield him, coverage of the case disappears from the internet, and a police superintendent orders the investigating unit to stop. The episode makes wealth tangible through the things that cease to function around it: scrutiny, publicity, and permission to investigate.
This is also where the romantic packaging starts doing delicate work. Yim makes Yi-jun’s controlling behavior entertaining through exaggerated expressions, eccentric gestures, and conspicuous clothes. His demands invite irritation, but the performance gives that irritation a comic rhythm.
The series supplies him with a lawyer inside the story and a persuasive casting decision outside it. Enjoying him becomes easy before trusting him becomes reasonable. That distinction gives the premiere some bite. Its prospective romantic lead remains a suspect, and the opening’s image of Eun-young’s body cannot be explained away by his amusing behavior.
Jae-hee’s resistance helps keep their exchanges from becoming demonstrations of his authority. She has entered his workplace to observe him, rather than to win his approval, and her willingness to oppose his demands preserves that investigative purpose.
There is a useful friction between her subordinate position and her private objective. The underfunded police unit needs evidence, including the victim’s missing second phone; Yi-jun expects control over the people around him. Their proximity puts those competing interests into daily contact, allowing the office relationship to carry some of the pressure created by the blocked investigation.
The route into that office is less convincing. Jae-hee gains access with surprisingly little recruitment scrutiny for a position close to an executive whose influence has already obstructed the police. Heightened comedy can accommodate an unlikely disguise, but the ease of the hiring weakens the particular obstacle the episode has constructed.
Yi-jun is difficult to reach through public institutions and comparatively easy to reach through his personnel department. A stronger account of that access would give Jae-hee’s resourcefulness greater weight. Here, the story grants her the proximity it needs rather readily.
Once she is inside, observation gives the comedy, investigation, and prospective romance a shared activity. Jae-hee must study Yi-jun closely while concealing why she is interested; his own watchfulness turns that attention back on her. This is a firmer connection between the genres than simply alternating a murder clue with a joke.
On her first day, he pulls her close, removes her spy glasses, and says, “Busted.” The gesture brings the physical intimacy promised by the romance directly into contact with the exposure feared by the investigator. Jae-hee has secured a place beside him without securing control of what he sees. The episode stops before she can discover how much of her assignment remains secret.

The Review
Love in Disguise
Love in Disguise makes an entertaining first impression by giving its disguised heroine a purpose that survives the romantic setup. Seol In-ah’s physical confidence and Yim Si-wan’s comic eccentricity sustain a relationship built on competing acts of observation. Corporate protection gives the investigation social weight, though Jae-hee’s easy recruitment weakens that obstacle. The premiere earns interest through the uneasy proximity between professional suspicion and romantic appeal.
PROS
- Jae-hee’s competence shapes the central relationship.
- Yim makes an unsettling suspect entertaining.
- Corporate influence creates concrete investigative obstacles.
- Mutual scrutiny connects comedy, romance, and suspense.
CONS
- Convenient recruitment weakens the undercover setup.
