SBS action drama “Agent Kim Reactivated,” starring So Ji-sub, is drawing strong viewership momentum in 2026. Multiple reports say the series has quickly climbed in audience ratings, reaching 18.8% nationwide after its third episode and surpassing 20% by the fourth episode. Nielsen Korea data cited by The Korea Times puts the fourth episode at 21.6% nationwide, which places it among the higher-performing SBS Friday-Saturday dramas of recent years. The series premiere is reported to have started at 9.5%, then increased to 15.7% in the second episode and 18.8% in the third before crossing 20% in the fourth.
The drama is described as following Kim, a former special agent played by So Ji-sub, who now lives a quieter life working at a small bank. His transition is tied to the final wishes of his late wife, who asks him to “just live as a father.” The plot shifts when his only daughter is kidnapped, prompting Kim to use his fighting skills to rescue her. The Korea Times also notes that the show’s success centers on the theme of a father’s love.
