What Is “Agent Kim Reactivated” About?
“Agent Kim Reactivated” is an action revenge drama that tells the story of Manager Kim (So Ji Sub), a seemingly ordinary dad with a secret past who puts everything on the line to save his beloved daughter.
It’s the classic “don’t mess with a dangerous man who chose peace” setup — and when it’s done right, it’s utterly irresistible. The webtoon source material already has a devoted fanbase, and the drama adaptation is shaping up to honour that legacy in every casting choice.
Meet the New Characters
Joo Sang Wook as Joo Kang Chan — The Villain
Joo Sang Wook plays Joo Kang Chan, a legendary figure from the bottom who started as a hired gangster and rose to become the chairman of Juhak Construction — a man who solves problems with money and violence.
This is a massive deal because, as Joo Sang Wook himself explained: “This is my first time taking on a villainous role, and as an actor, the various facets of evil that the character Joo Kang Chan portrays in the drama felt very intriguing and refreshing.” First-time villain energy from a seasoned actor is always something special to witness.
Son Naeun as Sang Ah — The Mysterious Ally
Son Naeun plays Sang Ah, a co-worker at the same company as Manager Kim and a mysterious figure who steps in to help him when he has trouble figuring out how to deal with his daughter Min Ji.
Son Naeun shared her thoughts, saying: “I was curious about the character Sang Ah, who holds a mysterious secret. It also appealed to me as a new genre to try, and above all, I was excited and happy to be able to act alongside the director and senior actors.”
An ally with secrets of her own — in an action revenge drama — means Sang Ah’s story is guaranteed to be more complex than it initially appears.
Why This Drama Deserves Your Attention
The webtoon-to-drama pipeline in Korea has produced some of the genre’s most beloved stories in recent years. Wikipedia’s overview of webtoons explains why the format produces such naturally dramatic and fast-paced source material — exactly what Joo Sang Wook praised when he described the original as “the fast-paced plot that keeps you on the edge of your seat.”
