After 15 years away from MBC, Gong Hyo-jin has finally returned with the new drama Killer Mommy, adapted from the hugely popular webtoon with 170 million views, which officially premiered on July 31, 2026. This time, she takes on the role of a “double-life wife”: a gentle homemaker by day and a cold-blooded sniper by night. Starring opposite Jung Joon-won as her passionate reporter husband, she brings a striking contrast to the role, while the satisfying scenes of punishing villains make this action drama one not to miss this season.
We’ve rounded up the 3 highlights of Killer Mommy that you definitely won’t want to miss. Let’s see just how charming this “housewife superhero” is.
Highlight 1: An ordinary housewife by day, a legendary sniper by night
In the drama, Gong Hyo-jin plays the lead character Ryu Bo-na. On the surface, she is an utterly ordinary housewife who carefully looks after her husband and daughter every day. The moment she receives a mission, though, she instantly transforms into “Kingfisher,” a legendary sniper who is cold and ruthless in her hunt for violent criminals.
This dual identity, full of gray areas, is exactly what makes the character so compelling. Watching her switch in an instant from a gentle wife to a perfectionist killer is satisfying enough on its own.
Highlight 2: With a passionate reporter husband at her side, could her double life be exposed at any moment?
Jung Joon-won plays Kwon Tae-sung, Ryu Bo-na’s husband, a passionate reporter with a strong sense of justice who is also completely devoted to his wife. The most interesting tension between the two lies in this secret that could be exposed at any moment.

Although her husband never sees his wife carry out an assassination mission firsthand, viewers get plenty of thrills from their all-knowing perspective as they watch the couple pull against each other across light and shadow, each hiding things from the other. This suspense-tinged married life adds the fun of knowing without saying to what might otherwise be a straightforward action drama.
Highlight 3: The wild “Sales Team 3,” disguised as an electric fan company
If the protagonist were fighting alone, it might not be quite satisfying enough. The drama also hides an assassination team called “Sales Team 3,” which poses as employees at a large corporation.
This dream team of assassins includes an accident specialist played by Sung Dong-il, a genius hacker played by Mu Jin-sung, and skilled actors including Kim Nam-hee. On company trips, they clumsily embarrass themselves while playing games, yet the moment they hear the signal to fight, they can immediately subdue hulking criminals. They make construction-site falls, car explosions, and other incidents look completely seamless, all to make their targets disappear from the world.
There have been no shortage of works centered on women’s revenge or assassination over the past two years, yet Killer Mommy cleverly combines the lightness of a family comedy with the cold edge of crime action. Through extensive use of flashbacks, it retains a warm sense of humanity amid all the satisfying action.
Now that the series premiered on the evening of July 31, add it to your watchlist if you enjoy this kind of satisfying drama with an unexpected contrast and hard-hitting action.
