A Bona Fide Killer Setup: Love, Lies, and A Very Risky Marriage
The upcoming action drama follows Yu Bo Na (Kong Hyo Jin), an ordinary-looking sales team manager at Durumi Electronics who moonlights as Kingfisher, a legendary sniper who takes down criminals. At home, though, she’s simply a warm, loving wife devoted to her husband. That husband happens to be Kwon Tae Sung (Jung Jun Won), a fearless investigative reporter who fully supports his wife’s return to work after a three-year break — completely unaware that his newest big story is chasing the very person sleeping beside him.

What the New Stills Reveal
The freshly released images lean into that contrast hard. One set shows the couple in a picture-perfect domestic moment, sharing warm smiles and an easy back hug that sells their chemistry as a genuinely loving pair. Another set flips the tone entirely, with Yu Bo Na locking her husband in an intense, almost intimidating stare while he cautiously reads the room — a glimpse of the playful tension that runs underneath their marriage.
It’s a clever visual setup: two people who adore each other, secretly working against one another without either fully realizing it yet.
Behind the Scenes
The production team has highlighted the married chemistry between Kong Hyo Jin and Jung Jun Won as one of the drama’s core strengths, describing their sweet-yet-dangerous double lives as central to the show’s appeal, blending everyday domestic warmth with the suspense of a killer-versus-reporter storyline.
