Why Jung Jun Won Took The Role

The Chemistry Behind The Camera
The two clearly built real warmth on set. Jung Jun Won described Kong Hyo Jin as an actor with such immense power that she makes her co-star’s heart flutter just by being on set, adding that he was happy just to be working with her and that their chemistry was fantastic. He also spoke fondly of co-star Lee Sang Yi, saying his unique positive and bright energy was a great stimulus, and that the two spent time together like real friends off screen.
What The Drama Is Really About
Beyond the sniper rifles and secret identities, Jung Jun Won sees something deeper at the story’s core. He defined “A Bona Fide Killer” as “the love of a family,” emphasizing that his ultimate goal in playing Tae Sung is to show what love between family members truly is.
The Story So Far
Yu Bo Na and Kwon Tae Sung have been married for five years and have a four-year-old daughter, with Bo Na never revealing her identity as a killer to anyone, even her own husband. Meanwhile, Lee Dong Jin (Lee Sang Yi) discovers a bullet at a crime scene and senses that Kingfisher has returned, launching an investigation that puts his career on the line</cite>.
The series continues MBC’s tradition of blending high-stakes action with grounded family drama, a combination that has become a signature of Korean television dramas in recent years.
