Love in Disguise

Yim Si-wan steps into the role of Yoon Yi-jun, a charismatic heir to the Taekang Group who suddenly finds himself the prime suspect in a brutal murder. The situation turns dire when Yi-jun insists on his innocence while unknown forces hunt him down. To protect her client and prove his guilt or innocence, Detective Kang Jae-hee makes a bold move. She sheds her identity as a female officer to become a male secretary inside Yi-jun's company.

This high-stakes ruse sets off a chain reaction of comedic misunderstandings and intense action sequences. Seorina brings physical grit to the role of Jae-hee, utilizing her special forces background to navigate corporate espionage and street-level threats. The series premiered on October 19, 2026, on tvN before hitting Amazon Prime Video globally. It blends the lighthearted tropes of office rom-coms with darker psychological suspense, exploring how trust dissolves when everyone wears a mask. [edit]

The narrative unfolds within the dual worlds of high-powered corporate governance and gritty criminal investigation. Yoon Yi-jun lives under constant threat from shadowy figures who want him silenced. He maintains a public image of confidence while privately fearing for his life. Detective Kang Jae-hee enters this volatile environment not as an interrogator but as a subordinate. Her mission requires her to maintain a male persona while living in close quarters with the man she is supposed to be protecting.

As Jae-hee navigates the daily rhythms of the Taekang Group, friction builds between her professional duties and her growing personal connection to Yi-jun. The show thrives on the tension of their respective disguises. Yi-jun suspects nothing about the gender of his new secretary, creating a layer of dramatic irony that fuels both humor and romance. Meanwhile, Jae-hee must suppress her tactical instincts to avoid blowing her cover during tense moments.

The first season establishes a twelve-episode arc focused on uncovering the truth behind the initial murder accusation. Viewers watch as the two leads rely on each other for survival while navigating office politics and external threats. The tone shifts frequently, moving from slapstick comedy born of mistaken identity to heart-pounding action scenes where Jae-hee uses martial arts to neutralize attackers. This genre-bending approach keeps the story unpredictable. The central mystery drives the plot forward, asking whether the detective can solve the crime without falling for the suspect she is sworn to protect.

Supporting characters add depth to the corporate setting. Colleagues at the company react to the new secretary with suspicion or curiosity, unaware of the deception unfolding beneath the surface. The pressure mounts as the investigation widens and more people get involved. Each episode peels back another layer of the conspiracy surrounding Yi-jun. The stakes rise as the clock ticks toward a potential resolution or a catastrophic failure of their cover.[edit]
