So Ji Sub is back on SBS for the first time in 13 years — and he did not come quietly. "Agent Kim Reactivated" (κΉ€λΆ€μž₯) premiered June 26, 2026 to the highest ratings of any SBS miniseries this season. The action revenge drama landed with an episode 1 rating that immediately set it apart from everything else airing right now.

13 years. That's how long it's been since So Ji Sub last led a drama on SBS. The anticipation was real. Apparently, so was the delivery.

What Is Agent Kim Reactivated?

"Agent Kim Reactivated" (μ‘΄λ‚˜λΌλŠ” κΉ€μš”μ›, also known as κΉ€λΆ€μž₯) follows a former black ops agent who is forced out of retirement to settle old scores. It's an action-revenge setup — think sharp suits, sharper fights, and a lead actor who has been waiting 13 years to prove he still has it. Spoiler: he does.

The drama airs on SBS on Fridays and Saturdays. Episode 1 premiered June 26 to strong viewership numbers, earning it the title of highest-rated SBS miniseries premiere of 2026 according to Nielsen Korea.

Why So Ji Sub's Return Is a Big Deal

So Ji Sub was one of the defining actors of K-drama's golden era — "I'm Sorry I Love You," "Master's Sun," "Oh My Venus." His return to SBS specifically, the network where he built a lot of his legacy, carries real symbolic weight. Korean fans have been waiting. And episode 1 ratings suggest they showed up.

He's also 49 in 2026 — an age where a lot of male actors transition to supporting or father roles. So Ji Sub chose to lead a full action drama instead. That's a statement.

πŸ‡°πŸ‡· The Korean Side

Korean viewers immediately flooded Nate Pann and Naver with comments after episode 1. The dominant reaction: relief that So Ji Sub chose a project worthy of his comeback. Korean fans tend to be critical of "nostalgia casting" — returning stars who coast on old goodwill with weak material. The early consensus is that "Agent Kim Reactivated" is not that. The action sequences in particular drew praise, with fans noting that So Ji Sub looks like he trained seriously for the role.

🌍 The Global Side

International viewers are discovering So Ji Sub for the first time through this show — and then immediately falling into his back catalog. Reddit threads are filling up with "where do I start with So Ji Sub" posts. For fans who grew up on classic K-dramas, this is a reunion moment. For newer fans, it's an introduction to a generation of acting they may have missed.

πŸ“Š The Gap

Korean audiences are watching this show with 13 years of context. Every scene carries the weight of his absence from SBS specifically. International viewers are coming in fresh — which actually gives the show something interesting: it works as a standalone action drama AND as a comeback vehicle. That dual audience is why the premiere ratings hit the way they did.

Is Agent Kim Reactivated Worth Watching?

If you like action-revenge dramas with a charismatic lead and high production values — yes. Early episodes suggest tight pacing, solid supporting cast, and an actor who is clearly invested. It's available on SBS with international streaming access through various platforms depending on your region.
