[Edaily Starin Choi Hee-jae Reporter] Jeong Jun-won, the "married-woman killer," was shocked to see his wife Gong Hyo-jin's true self.

In Episode 13 of the MBC Friday-Saturday drama “Married Woman Killer,” which aired on the 11th, Leila (played by Lee Eliya) orchestrated a crime modeled after the “Kingfisher” case out of resentment toward Yoo Bo-na (played by Gong Hyo-jin), and the two women’s troubled past was revealed.
According to Nielsen Korea, the episode recorded a 9.6% rating among households nationwide and a 9.1% rating in the Seoul metropolitan area, maintaining its position as the top-rated Friday-Saturday drama. In particular, the ending scene—where Yoo Bo-na turned her head at Leila’s words, “You should be ruined just like this. Lose everything that’s precious to you,” as Yoo Bo-na turned away and exchanged a glance with her husband Kwon Tae-sung (played by Jung Jun-won), who had been watching the entire situation unfold, pushed the instant peak viewership rating to 12.1%.
The 2054 viewership rating—a key indicator of channel competitiveness reflecting changes in the media consumption landscape—stood at 3.1%, ranking first among all programs aired that day and demonstrating the show’s resilience as the undisputed frontrunner.
In that day’s episode, public opinion toward Kingfisher shifted dramatically after a Kingfisher copycat sniped two innocent civilians. Kwon Tae-sung pointed out that the victims were completely different from Kingfisher’s usual targets over the past 15 years, raising the possibility of a copycat crime. In response, Lee Dong-jin (played by Lee Sang-yi) snapped, “Why do I feel like you’re covering for Kingfisher?” and the two men doggedly pursued the truth of the case through their respective reporting and investigations.
Yoo Bo-na speculated that the purpose of this copycat crime was to bring about Kingfisher’s social downfall. Sales Team 3 reaffirmed their determination to catch the culprit before a third victim emerged and set out to track down the suspect using CCTV footage. After examining the route taken by the man in the wheelchair who lured the victim, Sales Team 3 discovered that his path formed the shapes of a crescent moon and an eye.

Yoo Bo-na recalled a mysterious woman who had once said, “The eyes are the vital point of every beast.” Additionally, Sergei (played by Shin Hyun-soo) made a cryptic remark about the copycat’s identity, saying, “Someone who can imitate Kingfisher and wants to bring it down,” which unsettled Yoo Bo-na.
In particular, scenes from Yoo Bo-na’s time in Russia in 2008 were revealed, heightening the drama’s immersion. At that time, Leila shocked viewers by shooting the eyes of a young girl who had witnessed Yoo Bo-na’s sniper attack without hesitation.
Enraged by Leila’s cruelty—which even harmed innocent people—Yoo Bo-na went to see Mama (played by Moon Jung-hee) and protested vehemently. Ultimately, Yoo Bo-na left the Russian organization she had been a part of for so long, leaving a heavy, lingering impression. Furthermore, Leila was expelled from the organization following this incident and went on to work as a contract killer; harboring a twisted grudge against Yoo Bo-na, she set her sights on Korea.
Meanwhile, a man in a wheelchair disguised as a delivery driver handed a package to Kwon Tae-sung, setting the stage for a tense, life-or-death crisis. At that moment, Yubona appeared, and inside the package was a chilling message from Leila: “Your name will be on your gravestone after you die, and your sins will be passed on to your children even after you’re gone.” The tension mounted as the scene shifted to Yubona receiving a call informing her that her daughter, Kwon Yul (played by Hwang Bom-i), had gone missing.
Meanwhile, Lee Dong-jin tracked Leila’s movements based on a strand of hair belonging to a woman in her 30s that he found at the sniper attack scene. He identified a clear connection between Leila—who had a crescent moon and eye-shaped tattoo—and the victims who had been shot in the eye. Additionally, Kwon Tae-sung, who had been conducting a relentless investigation, uncovered a crucial clue revealing that the two victims knew each other, bringing him closer to the truth.
Toward the end of the episode, Yoo Bo-na and Leila finally came face to face. Leila expressed a twisted hostility toward Yoo Bo-na, who was living happily with her family in a world that idolized Kingfisher as a hero. Yoo Bo-na pointed a gun at Leila and coldly warned her not to touch her family. However, Leila responded with a meaningful smile, saying, “You, too, should experience hell while you’re still alive. Try grieving after losing everything you hold dear.”
Kwon Tae-sung, who happened to be at the scene, was shocked to witness his wife Yoo Bo-na’s ruthless and unfamiliar true nature. As a single gunshot rang out amid the breathtaking standoff between the three, anticipation for today’s finale reached its peak.
“The Married Woman Killer” is a drama depicting the struggles of a working mom with the world’s deadliest job as she fights to maintain a work-life balance. The finale, airing on the 12th, will be extended by 10 minutes and broadcast at 9:40 p.m.
