A Chaebol Heir, a Hidden Investigator, and a Murder Charge
The drama follows Yoon Yi Jun (Yim Si Wan), heir to the powerful Taegang Group, who becomes the prime suspect in a murder case. Enter Kang Jae Hee (Seol In Ah), a former special forces officer who goes undercover as his personal secretary to dig into the truth. It’s based on the popular web novel and webtoon “Why Don’t You Know She’s a Woman?” — a premise that promises equal parts romance, comedy, and thriller tension.
Script Reading Reveals Character Depth
At the September 4 script reading, attended by director Park Dan Hee and scriptwriter Moon Soo Jung, the cast gave a glimpse into how they’re shaping their roles:
- Yim Si Wan brings subtle emotional shifts to Yoon Yi Jun, balancing a guarded, distant exterior with flashes of vulnerability.
- Seol In Ah injects bold, energetic confidence into Kang Jae Hee’s undercover persona.
- Kim Jung Hyun plays Kim Si Hyun, Yoon Yi Jun’s loyal attorney friend with a mysterious hidden side.
- Yeonwoo rounds out the cast as Lee Hye Jung, a composed secretary whose true personality shifts dramatically after hours.
The production team teased that the “unexpected relationships” between these very different characters will drive much of the show’s fun and unpredictability.
