What it is about
A Bona Fide Killer (유부녀 킬러) is an MBC Friday–Saturday drama that began on 31 July 2026. Financial News and Star News describe it as the story of a working mother with the most brutal job in the world fighting to hold on to her work–life balance.
머니투데이 describes Yoo Bo-na, played by Gong Hyo-jin, as a woman who runs contract killing alongside raising a child, and Kwon Tae-seong, played by Jung Jun-won, as a newspaper social-affairs reporter chasing his wife’s other face. The Korea Times reported that Yoo Bo-na returns from parental leave to the sales team of Durumi Electronics, that the company is a front for a contract-killing operation, and that she targets criminals who received light sentences. Detective Lee Dong-jin, played by Lee Sang-yi, is chasing the identity known as “Kingfisher”. Kim Eun-hee wrote the series and Yoon Jong-ho and Kim Ji-hoon directed. It is adapted from the webtoon of the same name.
Why it drew attention at home
The ratings rose as the run went on. 머니투데이 gave episode one at 7.4 per cent and episode two at 8.0; Financial News reported on 15 August that episode five set a new high at 9.8 per cent; News1 reported a further high of 10.2 per cent on 16 August; and Star News wrote on 23 August that the eighth episode, broadcast the day before, took 8.8 per cent. All are Nielsen Korea nationwide figures.
How it ended
머니투데이 and 일간스포츠 reported that the finale, broadcast on 12 September, drew 10.7 per cent nationwide — a new high for the series — with a metropolitan average of 10.4 per cent. The momentary peak of 12.5 per cent came in the scene where, six months after Yoo Bo-na leaves, Kwon Tae-seong watches the first snow and remembers the mountain lodge. On the 20–54 measure the broadcasters use for competitiveness it took 3.2 per cent, first among every programme aired that day.
