Love in Disguise: A Chaebol Heir, a Murder Suspicion and a Detective Pretending to Be His Male Secretary

A new tvN teaser has fans talking, and it’s easy to see why. Love in Disguise pairs romance with suspense in a story where the person closest to the suspect is secretly investigating him. Yim Si Wan stars as Yoon Yi Jun, the arrogant third-generation heir to Korea’s top conglomerate and a murder suspect. Seol In Ah plays Kang Jae Hee, a former special forces officer turned detective who goes undercover as his personal secretary while pretending to be a man.

Love in Disguise: Drama Overview

Inside the Teaser

The clip opens with women gushing over how handsome Kang Jae Hee is, until someone blurts out, “Detective, are you a woman?” A rundown of her credentials follows, from martial arts skills to special forces experience, before she starts her new job.

Then comes the moment that steals the show. Yoon Yi Jun tells her that, regardless of gender, his personal secretary must put him above everything else, unconditionally. When she hesitates, he declares her application “rejected.” She quickly blurts out, “I will like you unconditionally!” It’s funny, tense and flirty all at once, and it hints at the push-and-pull between the leads.

Why It Looks Promising?

The premise plays with a classic setup: a suspect who might be dangerous, an investigator who must stay close to him, and a secret that could unravel at any moment. Mixing this with the tone of a workplace tvN romance gives the drama a fun, high-stakes energy.

If you want to warm up before the premiere, you can watch Seol In Ah in Oh My Ghost Clients and Yim Si Wan’s film Boyhood on Viki.
