So Ji Sub Is Back — and This Time He’s a Deadly Secret Agent Hiding Behind a Dad Bod

The K-drama world just got its most exciting new premise of the summer: So Ji Sub playing the world’s most ordinary-looking dad who also happens to be the world’s most dangerous operative. And first-look stills confirm it’s going to be exactly as thrilling as it sounds.

What Is Agent Kim Reactivated About?

Agent Kim Reactivated is an action revenge drama about Manager Kim — the most ordinary dad in the world who becomes the most dangerous man in the world to save his one and only beloved daughter.

The premise walks a brilliant line between domesticity and danger. Manager Kim avoids confrontation with troublemakers on his way home from work, acts timidly when threatened, and presents himself as a completely ordinary employee at a midsize savings bank — but this is all a desperate attempt to hide his identity as the No. 1 target on a top-level most-wanted blacklist. In reality, he is Code Name 66, a North-South Korean operative.

A retired spy going full “protective dad mode” is a formula Korean action drama does exceptionally well — and with So Ji Sub leading the charge, expectations are high.

So Ji Sub on Playing Manager Kim

So Ji Sub described Manager Kim as a doting father who cherishes his daughter and a mysterious figure surrounded by secrets — on the surface an ordinary, approachable father, but underneath a dual-sided character who hides secrets and a past no one can easily access. He hopes viewers will follow Manager Kim’s story as it gradually unfolds.

That tension between warmth and danger is exactly the kind of layered character So Ji Sub does best, and this role seems purpose-built for his range.
