Chaebol heirs, undercover detectives, and mistaken identity — tvN’s upcoming romance thriller *Love in Disguise* is leaning hard into playful role-reversal dynamics, and its newest posters make that abundantly clear.

## You’ve Committed a Crime: Premise

*Love in Disguise* follows **Yoon Yi Jun** (Yim Si Wan), an arrogant third-generation chaebol heir who suddenly becomes a murder suspect, and **Kang Jae Hee** (Seol In Ah), a former special forces officer turned detective who goes undercover as his personal secretary to investigate him from the inside. There’s a twist complicating things further: Kang Jae Hee adopts a false identity so convincing that Yoon Yi Jun mistakenly believes his new secretary is a man.

That mistaken-identity setup opens the door for exactly the kind of tension-meets-comedy dynamic that’s driving the show’s marketing.

## Love in Disguise: The Two New Posters

tvN released a pair of “role-reversal” posters that flip the classic K-drama rescue trope on its head:

**Poster 1** shows Kang Jae Hee catching Yoon Yi Jun in a firm, steady hold — fitting for a former special forces officer. Yoon Yi Jun, meanwhile, looks completely relaxed in her arms, unbothered rather than flustered. Its tagline: **“You’ve committed a crime. The crime of making my heart race.”**

**Poster 2** flips the dynamic: Yoon Yi Jun holds Kang Jae Hee in a dance-like dip, hands tightly clasped, signaling a chemistry that’s moved well past employer-employee territory. Its tagline mirrors the first: **“You’ve committed a crime too. The crime of making my heart race.”**

The matching taglines suggest a couple whose power dynamic keeps shifting — a nice visual metaphor for a story built on disguise and unequal knowledge between the two leads.

| Character | Actor | Role |

| Yoon Yi Jun | Yim Si Wan | Chaebol heir, murder suspect |
| Kang Jae Hee | Seol In Ah | Undercover detective posing as his secretary |
