Seo Ji-hye Joins Park Hae-soo in ENA Crime Thriller The Scarecrow

Park Hae-soo (박해수) is returning to Korean television in a way nobody expected. The actor, globally recognized as Cho Sang-woo in Netflix’s Squid Game, is set to headline ENA’s upcoming crime thriller The Scarecrow (허수아비). Now confirmed alongside him: Seo Ji-hye (서지혜), whose casting as his onscreen sister completes one of the most intriguing sibling dynamics seen in Korean crime drama in years.

A Detective, His Sister, and a Serial Murder Case

The Scarecrow centers on Kang Tae-ju, an elite detective reassigned to his hometown of Gangseong under a cloud. While pursuing the real culprit behind a serial murder case, he finds himself in an unexpected joint operation with someone he despises. It is the kind of setup that defines the best Korean crime thrillers: morally complex, tension-layered, grounded in place.

Seo Ji-hye plays Kang Soon-yeong, Tae-ju’s younger sister. A warmhearted elementary school teacher who adores children, Soon-yeong becomes entangled in an incident no one saw coming. Seo Ji-hye will chart her character’s transformation from bright and sharp-tongued to psychologically unraveling with delicate range. That description tracks for anyone who watched her command Family by Choice.

Park Hae-soo’s Long-Awaited TV Return

Park Hae-soo earned an Emmy nomination for his portrayal of Cho Sang-woo in Squid Game Season 1 and has since moved through a string of high-profile projects: Money Heist: Korea, Narco-Saints, Karma. The Scarecrow marks his return to the ENA Monday-Tuesday slot, and he is playing Kang Tae-ju with the kind of moral weight that suits him best. His best characters carry damage, competence, and contradictions in equal measure. Tae-ju, a decorated detective forced back to where he started, sounds like Park Hae-soo at his most natural.

A Cast Built to Deliver

The ensemble surrounding the siblings is sharp throughout. Lee Hee-joon, known for Karma and The Price of Confession, joins the cast alongside Kwak Sun-young, who made her mark in Crash. Director Park Joon-woo, who previously helmed Crash, reunites with Kwak Sun-young here, while writer Lee Ji-hyun brings experience from the Taxi Driver series. The production lineup signals a drama team with crime-thriller DNA throughout.

The Scarecrow is produced by Studio Anjilen and planned by KT Studio Genie. It will air on ENA in the Monday-Tuesday slot in the first half of 2026, with simultaneous availability on KT Genie TV.

Why the Sibling Dynamic Matters

Sibling relationships in Korean crime dramas tend to serve as backstory rather than plot engine. The Scarecrow appears to flip that entirely. The fact that Kang Soon-yeong becomes entangled in an unexpected incident suggests she is not peripheral support for her brother’s investigation. She may be central to it. Whether that positions her as witness, victim, or something far more complicated, the show is setting up a collision between a detective’s professional instincts and his personal loyalties. That tension, executed properly, is what separates good crime dramas from genuinely great ones.
