Scheduled to premiere on Friday, June 26, SBS's new Friday-Saturday drama Agent Kim Reactivated (written by Nam Dae-joong, directed by Lee Seung-young and Lee So-eun) is a "father-universe" revenge action drama. It follows a "most ordinary" father who becomes the "most dangerous" man to fight a desperate battle to rescue his only daughter.

In the series, Joo Sang-wook plays Ju Gang-chan, a ruthless figure who started as a hired thug and rose to become the chairman of Juhak Construction—a legendary rags-to-riches story who resolves everything with money and violence. On the other hand, Son Na-eun portrays Sang-a, a mysterious colleague who works at the same company as the protagonist, Manager Kim (played by So Ji-sub). She is a sharp-witted coworker who helps him navigate the difficulties of raising his daughter, Minji, while harboring her own secrets. The two characters are set to become deeply entangled with So Ji-sub's titular character, serving as the main drivers of the drama's conflict and mystery.

The newly released stills on June 4 instantly capture attention with the actors' striking visuals. First, Joo Sang-wook exudes a chilling, intimidating presence in a sauna, revealing burn scars covering his body and a sharp, piercing gaze. In contrast, Son Na-eun, dressed in neat office wear, looks like a savvy Gen Z employee who speaks her mind. However, her suspicious gaze as she closely watches Manager Kim's every move heightens the mystery surrounding her character.

Taking on his first villain role since his debut, Joo Sang-wook shared his excitement: "I decided to join the project because the original webtoon is so powerful, and the fast-paced, relentless plot is incredibly entertaining." He added, "The various facets of evil portrayed by Ju Gang-chan felt very interesting and fresh to me as an actor. I focused on visually conveying an intimidating and dark aura while maintaining the dignity of a construction company chairman."

Son Na-eun, making her return in a genre series, also expressed her determination: "I was intrigued by Sang-a, a character with mysterious secrets, and the genre itself was an exciting new challenge for me." She continued, "This character required more preparation and attention to detail than any role I've played before. I put a lot of thought into everything from her head-to-toe appearance to her speech patterns and gestures to truly embody Sang-a."

The production team expressed strong confidence, stating, "Both Joo Sang-wook and Son Na-eun will showcase unprecedented acting transformations in Agent Kim Reactivated." They added, "As natural-born actors with incredible immersive power, we hope viewers look forward to their stellar performances as the core pillars of the drama's conflict and mystery."

Based on the popular Naver webtoon of the same name, Agent Kim Reactivated is set to premiere on Friday, June 26 at 9:50 PM KST.
