Some women can’t find balance between office meetings and school pickups. Yu Bo Na has it worse — she’s got a sniper rifle in one hand and her mother-in-law’s approval to chase with the other.

MBC’s upcoming action drama **“A Bona Fide Killer”** just dropped new stills of [Kong Hyo Jin](https://en.wikipedia.org/wiki/Gong_Hyo-jin) in her first MBC project in 15 years, and she’s playing the kind of double life that makes “work-life balance” sound like an understatement.

## Who Is Yu Bo Na, Really?

By day, she’s an unremarkable sales manager at Durumi Electronics. By… whenever duty calls, she’s **Kingfisher**, a legendary “one-shot, one-kill” assassin who’s spent years quietly erasing the world’s worst criminals. After three years on maternity leave, she’s stepping back into the field — while also stepping back into a house full of in-laws who have no idea who she really is.

## Why A Bona Fide Killer Role Feels Different?

Kong Hyo Jin has built her career on romantic comedies, but Yu Bo Na is a shift — a woman hiding lethal precision behind an ordinary cardigan and an even more ordinary in-law group chat. The tension between “sniper who never misses” and “daughter-in-law who’s always missing dinner” is exactly the kind of premise that makes K-drama fans lean in.
