Kong Hyo Jin And Jung Jun Won Share Why ‘A Bona Fide Killer’ Won Them Over

Kong Hyo Jin and Jung Jun Won are celebrating the release of A Bona Fide Killer, opening up about their characters, their on-screen partnership, and what made the action drama an easy project to embrace.

Story That Blends Action And Family

A Bona Fide Killer follows the double life of Yu Bo Na, a working mother who secretly operates as the legendary sniper known as "Kingfisher." While balancing family responsibilities, she faces dangerous missions that threaten the life she has carefully built.
Kong Hyo Jin leads the series as Yu Bo Na, while Jung Jun Won stars as her husband, Kwon Tae Sung, a determined news reporter investigating the mystery surrounding Kingfisher's return.
Kong Hyo Jin described the drama as something that immediately stood apart from typical action series.
"A Bona Fide Killer felt like a superhero story to me."
She explained that Bo Na's unique identity as a mother, wife, daughter-in-law, and professional killer made the character impossible to ignore.

Why The Drama Stood Out

Kong Hyo Jin also praised the structure of the series, saying each episode introduces a fresh case while steadily building the larger story.
She added that beyond the battle between good and evil, the emotional journey would likely resonate with mothers, married women, and even viewers preparing for marriage, making Bo Na's experiences feel especially satisfying.
Jung Jun Won shared a different perspective, explaining that despite its action-packed premise, the story is ultimately centered on family.
He said he approached Kwon Tae Sung by focusing on the character's devotion to protecting the people he loves.
