Netflix's Agent Kim Reactivated: So Ji Sub's New Action-Thriller Drops June 27 — Everything You Need to Know

So Ji Sub Is Back With a Brutal New Netflix Thriller

Mark your calendars, because one of the most anticipated K-dramas of summer 2026 is finally getting a release date. Agent Kim Reactivated, SBS's live-action adaptation of the wildly popular webtoon Manager Kim, will premiere on Netflix on June 27, 2026, with simulcast episodes airing every Friday and Saturday through July 25.

If you've been craving a hard-hitting action series with real emotional weight, this one checks every box. Here's everything you need to know before it drops.

The Plot: A Father's Nightmare Turns Into a One-Man War

The premise is straightforward but devastating. So Ji Sub plays Director Kim — a mild-mannered company manager and devoted single father who harbors a deadly secret: he's a former black-ops operative. When his daughter Min-ji is kidnapped, Kim sheds his quiet civilian life and unleashes hell on anyone standing in his way.

Netflix's official synopsis says Kim is "hell-bent on rescuing his daughter by any means necessary, even if it means destroying everything and everyone standing in his path." If that sounds like a recipe for some seriously cathartic action sequences, well — it absolutely is.

The series is directed by Lee Seung Young, who previously helmed the critically acclaimed drama Wonderful World, and written by Nam Dae Joong, known for the romantic comedy Love Reset. That combination of intense direction and sharp scripting is a promising sign.

The Cast: Five Stars Who Carry the Weight

The ensemble is stacked with talent that K-drama fans will instantly recognize:

• So Ji Sub as Director Kim — best known for Mercy for None, Doctor Lawyer, My Secret Terrius, and The Master's Sun. This is only his second Netflix project, and it looks like a return to form for the action-thriller genre.
• Choi Dae Hoon as Seong Han Su — you've seen him in Crash Landing on You, Extraordinary Attorney Woo, When Life Gives You Tangerines, and Pro Bono.
• Yoon Kyung Ho as Park Jin Cheol — a standout from The Trauma Code: Heroes on Call, Itaewon Class, All of Us Are Dead, and Vincenzo.
• Joo Sang Wook as Ju Gang Chan — known for The King of Tears, Good Doctor, and Grand Prince.
• Son Na Eun as Sang A — former Apink member turned actress, known for Agency, Ghost Doctor, and Cinderella and the Four Knights.

Why This Matters for K-Drama Fans

The webtoon Manager Kim by author Toy has a massive following, and this adaptation has been generating buzz since the cast announcement. With only 10 episodes running roughly 60 minutes each, the pacing should be tight and focused — no filler, just pure thriller momentum from start to finish.

Coming hot on the heels of the massive success of K-dramas like Squid Game and All of Us Are Dead, Agent Kim Reactivated has the potential to be Netflix's next Korean breakout hit. If So Ji Sub's track record in action roles is anything to go by, we're in for an absolute ride.
