Agent Kim Reactivated Just Made SBS History — And It’s Not Slowing Down

Some K-dramas peak in episode one and coast. Agent Kim Reactivated is doing the opposite — climbing higher with every single episode, and it just wrote itself into SBS’s record books.

The Numbers That Matter

Episode 6, which aired on July 11, pulled a nationwide rating of 22.3% according to Nielsen Korea — a new all-time high for the show and enough to make it the most-watched program on Saturday overall. That puts Agent Kim Reactivated at the second-highest rating of any Friday-Saturday drama in SBS history, trailing only The Penthouse 2, which peaked at 29.2% back in 2021.

Even more impressive: this isn’t a one-off spike. The show was already crowned the most-watched drama of 2026 the week before — and instead of plateauing, it kept climbing.

Why Everyone’s Talking About It

The premise is simple but effective: Manager Kim, played by So Ji Sub, is an ordinary dad hiding a dangerous past — and he’s forced to use it all to protect his daughter. That mix of family stakes and hidden identity is a formula Korean dramas have used before, but the execution here is clearly resonating on a national scale.

For those wondering how Nielsen ratings actually work in South Korea’s television landscape, the Nielsen Korea system tracks nationwide viewership the same way global Nielsen ratings measure audience share elsewhere — a key benchmark for how “hit” a drama really is.
