A quiet retreat to escape burnout was supposed to be simple. Instead, the next episode of “A Bona Fide Killer” turns a snowy mountain lodge into the setting for a tense search-and-collapse scene that deepens the show’s central romance.
A Bona Fide Killer: The Story So Far
Based on the hit webtoon of the same name, MBC’s “A Bona Fide Killer” follows Yu Bo Na (Kong Hyo Jin), the seemingly ordinary manager of Sales Team 3 at Durumi Electronics who’s secretly the legendary sniper known as “Kingfisher.” The previous episode revealed her history with Kwon Tae Sung (Jung Jun Won) — she once saved his life on a past mission, and the two later crossed paths again when he found her standing on the edge of a hospital rooftop. The series streams internationally on Viki.

What Happens In The New Episode
| Scene | Details |
|---|---|
| Mountain retreat | Burned-out Yu Bo Na heads to an isolated mountain lodge; Kwon Tae Sung stays close by her side |
| Sniper skills on display | She steps out to hunt for food, showing off her “one shot, one kill” precision |
| The scare | Kwon Tae Sung searches the mountain after she disappears with a hunting rifle, and ultimately collapses |
| A separate storyline | Lee Dong Jin (Lee Sang Yi) opens up about his painful past while performing memorial rites for his parents |
Why This Episode Matters
The mountain lodge sequence is doing double duty — it’s both a tender character moment between two people slowly falling for each other, and a reminder of how dangerous Yu Bo Na’s secret life really is. Kwon Tae Sung’s collapse while searching for her raises real stakes heading into the next stretch of episodes, and pairing it with Lee Dong Jin’s emotional backstory gives the show room to deepen its supporting cast without losing momentum on the central romance.
The new episode airs August 22 at 9:50 p.m. KST on MBC.
