Agent Kim Reactivated Cast Explained: So Ji-sub's Role
On this page
A mild-mannered savings-bank manager in glasses turns out to be one of the most dangerous men on the Korean peninsula, and that single reversal is the engine of Agent Kim Reactivated. The cast is what sells it. So Ji-sub plays the tired single dad first and the black-ops legend second, and the SBS drama climbed from a 9.5% premiere on June 26, 2026 to more than 20% nationwide by its fourth episode. The 10-episode run wrapped on July 25, so here is the full cast explained now that the story is complete.

Agent Kim Reactivated Cast Explained: Who’s Who in the Ensemble
Five actors carry the story: So Ji-sub as Manager Kim, Choi Dae-hoon and Yoon Kyung-ho as the two old friends who ride with him, Joo Sang-wook as the construction boss on the other side, and Son Na-eun as the co-worker who knows more than she says. SBS’s official character page sets them up like this:
| Actor | Character | Who they are |
|---|---|---|
| So Ji-sub | Manager Kim (김부장) | Accounting team manager at Sangsaeng Savings Bank; a retired black-ops agent, code name 66 |
| Choi Dae-hoon | Seong Han-su | Former Olympic taekwondo gold medalist who runs a taekwondo gym; Kim’s longtime friend |
| Yoon Kyung-ho | Park Jin-cheol | Former special forces soldier who volunteers with a Marine Corps veterans’ group; Kim’s other old friend |
| Joo Sang-wook | Joo Kang-chan | Rose from hired muscle to chairman of Juhak Construction; settles everything with money and force |
| Son Na-eun | Jung Sang-a | Trend-obsessed assistant manager at Kim’s bank who is hiding secrets of her own |
| Seo Su-min | Kim Min-ji | Kim’s daughter, a high-school sophomore whose disappearance starts the story |
The wider ensemble fills in both sides of the fight. Kim Sung-kyu plays North Korean operative Park Kang-seong, Lee Jae-yong plays North Korean intelligence chief Ri Eung-ryeong, and Won Hyun-jun plays the South Korean special-operations chief nicknamed Mole Cricket, one of the few people who knows who Kim used to be. Yoo Ji-an plays Kang-chan’s daughter Joo Hye-ri, and Lee Dong-ha, Park Jin-woo and Jo Bok-rae round out the supporting cast.
Who Does So Ji-sub Play in Agent Kim Reactivated?
So Ji-sub plays Manager Kim, a North Korean-born special operative who defected to the South, worked under the code name 66, and then walked away from that life to raise his daughter as an unremarkable bank employee. Netflix’s synopsis boils it down to an unassuming dad who dusts off his old black-ops skills when his daughter goes missing. Dual-identity heroes are a Korean thriller staple, but So Ji-sub plays this one more tired than slick: a widower who genuinely wanted the boring life to stick. The show lets you sit with the ordinary-dad routine before the agent resurfaces, so the switch lands harder than an action-heavy opening would.
What Happens in Agent Kim Reactivated?
The story kicks off when Min-ji vanishes after a school-violence incident and the clues point to a kidnapping. From episode 3, Kim, Han-su and Jin-cheol join forces to find her, and SBS’s episode 4 preview has Kim dodging the people assigned to watch him while he traces her whereabouts through a phone. By episode 6 he is squaring off against the Special Mission Bureau, the state agency that has kept tabs on him for years, to protect her. The finale aired on July 25, 2026 and ends on an open note, which is why season 2 talk started almost immediately.
Why Is Agent Kim Reactivated Netflix’s Breakout K-Drama of 2026?
The numbers are the short answer. Nielsen Korea’s nationwide ratings put episode 4 at 21.6% on July 4, 2026, more than double the premiere, and the show peaked at 23.1% with episode 8 on July 18 before finishing at 23.0%. Outside Korea, Netflix’s weekly Top 10 ranked it No. 1 among non-English shows with 10.5 million views in the week of June 29, and it held the top spot for three straight weeks. The source material matters too. The Naver Webtoon brings a built-in fanbase, and the “ordinary dad with a lethal past” premise travels without much cultural context, which is how it ended up being described as a Korean-style John Wick. If that blend of comedy and violence is your thing, The Apartment Job gives Ji Sung a similar ex-gang-boss setup with more laughs.
Frequently Asked Questions
Q: How many episodes does Agent Kim Reactivated have?
Ten. The series aired on SBS every Friday and Saturday at 21:50 KST from June 26 to July 25, 2026, and all 10 episodes are on Netflix.
Q: What does “66” mean in Agent Kim Reactivated?
It is Manager Kim’s old code name from his years as a special operative. That past is why North Korean agents and South Korea’s own Special Mission Bureau both take an interest once his daughter disappears.
Q: Is Agent Kim Reactivated connected to Lookism?
Loosely, yes. The drama adapts the Naver Webtoon “Manager Kim,” a spin-off set in Park Tae-jun’s shared webtoon universe, where Manager Kim first turned up as a supporting character in Lookism. You don’t need to have read either webtoon to follow the drama.
Q: Is Agent Kim Reactivated based on a true story?
No. It is adapted from the Naver Webtoon “Manager Kim” by Jeong Jong-taek and Toy, a fictional action series, not a true-crime account.
Q: Where can I watch Agent Kim Reactivated outside Korea?
On Netflix, which carries all 10 episodes internationally. That is worth checking before you go looking, because plenty of SBS shows never reach the service (Running Man is the classic example).
Q: Will Agent Kim Reactivated get a season 2?
Not officially, as of September 2026. Director Lee Seung-young told SBS News on July 31 that talks had begun in a positive direction, and co-producer Fantagio said on August 8 that it was discussing a second season, but no schedule or cast has been announced.
Now that every episode is out, the smartest way in is still the first four back to back: the jump from 9.5% to 21.6% happened across exactly that stretch, and the show front-loads its hooks fast enough that stopping after episode one undersells it. For another Netflix K-drama rooted in Korean source material, Mousetrap’s folktale origins make a good next watch.
