The drama follows Yoon Yi Jun (Yim Si Wan), an arrogant chaebol heir who suddenly finds himself a murder suspect, and Kang Jae Hee (Seol In Ah), a former special forces officer who goes undercover as his personal secretary to dig into the case. It’s based on the popular webtoon and web novel Why Don’t You Know She’s a Woman?
The teaser wastes no time building chemistry. Kang Jae Hee handcuffs Yoon Yi Jun, declaring there’s already enough evidence against him — only for him to flip the script, cuffing her hand right back and accusing her of committing a crime too. As he steps closer and she instinctively steps back, he delivers the line that’s sure to become a fan favorite: it’s the crime of making his heart race.
