Before the marriage, before the secrets, there was a rooftop. “A Bona Fide Killer” just released new stills revealing exactly how Kong Hyo Jin and Jung Jun Won’s characters first crossed paths — and it’s a lot more vulnerable than fans expected.
Note: this article contains spoilers.
The new episode digs into the past, showing Yu Bo Na (Kong Hyo Jin) at her lowest — burnt out from an endless cycle of missions as the vigilante sniper “Kingfisher,” standing precariously on a hospital rooftop. That’s when Kwon Tae Sung (Jung Jun Won), in a hospital gown himself, spots her and rushes over, desperate to talk her back from the edge.
What’s Coming in the New Episode
Beyond the emotional rooftop flashback, the stills also show a lighter side: Sales Team 3 at Durumi Electronics holding an emergency meeting to figure out what to bring to Yu Bo Na’s housewarming party, led by the ever-entertaining Kim Bong Pal (Sung Dong Il).

The production team teased that this episode reveals both Yu Bo Na’s past burnout and the real story behind her first meeting with Kwon Tae Sung — a much softer contrast to her usual composed, resolute demeanor.
