MBC's Friday-Saturday drama "Married Woman Killer" broke through a peak viewership of 9.4% and a national average of 7.4% from its very first broadcast, instantly capturing the living room ratings and announcing the glamorous return of Gong Hyo-jin as One-Shot-One-Kill Killer.
In the first episode of MBC's Friday-Saturday drama "Married Woman Killer," which aired on August 31 (planned by Kwon Seong-chang, scripted by Kim Eun-hee, directed by Yoon Jong-ho and Kim Ji-hoon, produced by Bon Factory, Barum Pictures, and Studio Pim), the precarious double life of Yu Bo-na (played by Gong Hyo-jin), who oscillates between an ordinary married woman and the legendary sniper "Kingfisher," was unveiled.
The viewership for that day's broadcast reached 7.4% based on Nielsen Korea's national household standards and 6.8% based on Seoul metropolitan area households, securing first place in the same time slot across all channels from its premiere. In particular, a scene where Kwon Tae-sung (played by Jung Jun-won) learned of Kingfisher's return via the news and fell into shock recorded an instantaneous peak viewership of 9.4%.
The first broadcast opened with a tense confrontation between daughter Oh Seung-ah (played by Do Young-seo), who reunited with her father Oh Man-seok (played by Kim Won-hae) upon his release from prison on Christmas Day 15 years ago. Although Oh Man-seok seemed to offer a regretful apology to his daughter, he suddenly turned hostile, saying, "I should have killed you that day too," and choked Seung-ah. At that moment, a bullet flew through the crack of an open window, striking Oh Man-seok, revealing Yu Bo-na aiming a sniper rifle from a rooftop across the way, delivering a thrilling shock. Immediately rushing to the rooftop, Seung-ah discovered the message "Merry Christmas" left in the snow and finally burst into tears, leaving a powerful impact.
Fifteen years later, in the present day, Yu Bo-na's ordinary life unfolds with her husband Kwon Tae-sung and daughter Kwon Yul (played by Hwang Bom-i). While appearing endlessly affectionate and gentle in front of her family, Yu Bo-na catches a falling cup with one hand and subdues a sexual harasser by accurately hitting him with groceries, revealing extraordinary traits that sparked curiosity about her true identity.
Meanwhile, Kwon Tae-sung received a tip about a new type of drug and headed to Mu-san. Equipped with a camera on his watch, he chased a man suspected to be a dropper into a nightclub. However, the dropper's vehicle suddenly exploded in a shocking incident, and an mysterious man appeared from afar, whispering, "Farewell. I can't wish you to be reborn," adding intense tension to the scene. Tae-sung went all the way to the Mu-san Police Station to relentlessly investigate the truth of the case and discovered that the explosion victim was not merely a dropper but a drug kingpin.
Meanwhile, Yu Bo-na returned to work as Deputy Manager of the Crane Electronics Sales Team 3 after completing three years of maternity leave. Team leader Kim Bong-pal (played by Sung Dong-il) immediately asked Yu Bo-na for a client meeting, and she unexpectedly replied, "Let's do it during the day. I have to pick up my child," leaving her team members flustered.
Later, Yu Bo-na went to the church rooftop and began skillfully assembling mysterious equipment while saying, "I know that even by accident, no one should be hurt, not even children." She then mounted a sniper rifle and aimed at a man in a hotel across the way, delivering a twist. With the words, "Client meeting begins," she instantly subdued her target and declared the end of the meeting with a cold expression. Additionally, Kim Bong-pal was seen gazing out the office window, muttering, "Farewell. I can't wish you to be reborn," revealing the identity of the man present at the scene of the Mu-san vehicle explosion incident, delivering another shock.

Yu Bo-na visited flower shop owner Baek Yoon-ok (played by Seo Jeong-yeon) and had a meaningful conversation about the meaning of the margaret flower. When told that the margaret's flower language is "revealing secrets" and "sincere love," Yu Bo-na replied, "It also has secrets because it loves too much." This was interwoven with flashbacks to her past in an orphanage, her time living as a killer, and the moment she first confessed her love to Kwon Tae-sung, further raising curiosity about Yu Bo-na's narrative.
Towards the end of the broadcast, breaking news speculated on the return of "Kingfisher" alongside a gun sniper incident. Overwhelmed by shock, Kwon Tae-sung froze in place, gazing at his family photo with anxious eyes. At the same time, Yu Bo-na received a warning letter containing not only photos of her husband Kwon Tae-sung and daughter Kwon Yul but also footage of the church rooftop sniper scene, completing a tense ending.
