Seven months, countless action sequences, and one record-breaking finale later — the cast of MBC’s “A Bona Fide Killer” is saying goodbye. A newly released making-of video takes fans behind the scenes of the drama’s very last shoot, and it’s every bit as heartfelt as the show itself.

## A Bona Fide Killer: Behind the Scenes of the Final Shoot

The footage opens with [Kong Hyo Jin](https://www.viki.com/celebrities/15888pr) and Lee Elijah rehearsing a demanding action sequence, nailing it with surprising ease. After an emotional scene opposite [Jung Jun Won](https://www.viki.com/celebrities/21865pr), director Kim Ji Hoon praised Kong Hyo Jin for staying sharp and focused through 15 straight days of filming, juggling both romance and action without a single complaint.

As the shoot wound down, the cast gathered for the school festival scene, turning the set into something closer to a celebration than a workday. Kong Hyo Jin shared that the wrap felt like a party, and said tackling action for the first time in her career pushed her out of her comfort zone — support from the crew, she noted, made her performance as Yu Bo Na possible.
