MBC’s upcoming action drama **“A Bona Fide Killer”** just dropped a new teaser, and it’s a wild ride between spreadsheets and sniper scopes. Marking her first MBC drama in 15 years, [Kong Hyo Jin](https://en.wikipedia.org/wiki/Gong_Hyo-jin) stars as Yu Bo Na, an unassuming sales manager at Durumi Electronics who’s secretly “Kingfisher” — a legendary one-shot, one-kill assassin.

## What A Bona Fide Killer Teaser Reveals?

The clip opens with a rooftop sniper shot slicing through a narrow gap, instantly setting the tone. Moments later, the mood flips — Bo Na stands before her sharp-tongued mother-in-law holding a kitchen knife, admitting she’s “not really used to using this for this kind of purpose.” It’s a clever wink at her double identity.

In a standout scene, her mother-in-law hurls an apple at Bo Na’s husband mid-argument — only for Bo Na to spin around and catch it one-handed, stunning her in-laws. The teaser then eases into softer, domestic beats before ending with Bo Na raising her rifle again, declaring, “The client meeting is now in session.”
