[Edaily Starin Choi Hee-jae Reporter] Gong Hyo-jin, known as the “Married Woman Killer,” created a tense moment as she found herself on the verge of having her true identity exposed by Jung Joon-won.

In Episode 5 of the MBC Friday-Saturday drama “Married Woman Killer,” which aired on the 14th, the episode featured a thrilling casino operation by Durumi Electronics’ Sales Team 3 targeting Tak Jong-gu (played by Kim Min-joon), a wealthy sexual assault offender, alongside the commotion at Yoo Bo-na’s (played by Gong Hyo-jin) in-laws’ memorial service.
According to Nielsen Korea, the episode recorded a viewership rating of 9.8% nationwide and 9.5% in the Seoul metropolitan area, setting a new series high. In particular, the scene where Assistant Manager Ki Young-do (played by Mu Jin-sung) failed in his mission to secure VIP tickets, prompting Yoo Bo-na to step in personally to resolve the situation, saw the instant viewership rating soar to 11.4%, sending viewers’ dopamine levels through the roof.
In that episode, Kwon Tae-sung (played by Jung Jun-won) was plagued by a nightmare in which he was bound head to toe in the mountains, hinting at his shrouded past. Additionally, Yoo Bo-na discovered a bugging device inside a doll sent by her Russian friend Seul-gi and issued a chilling warning: “If you pull this stunt one more time, I’ll have you struck by lightning.”
The new target of Durumi Electronics’ Sales Team 3 was Tak Jong-gu, the youngest son of a “royal family” with a father who is a member of the National Assembly and a mother from a chaebol family. Despite committing various crimes against women, he had been sentenced to a two-year suspended sentence and was now frequenting casinos. Yoo Bo-na revealed her grim determination, saying, “If possible, I’d love to hit the jackpot on the day of our meeting. So that the day of greatest joy becomes his funeral day,” revealing her ruthless determination. However, when she received a call from her mother-in-law, Ok Seon-ja (played by Cha Mi-kyung), she suddenly remembered her own in-laws’ memorial service, creating a humorous twist as she oscillated between being a killer and a real-life housewife.
At the same time, Kwon Tae-sung was covering the fall accident involving Kang Young-ho (played by Jeon Chi-hwa) of Gaecheon Construction and picked up on some suspicious circumstances. He was skeptical that Chairman Cheon Seong-gil (played by Kim Jong-gu) had personally stepped in to offer compensation, even though the accident was caused by Kang Young-ho’s negligence. He then uncovered new clues—that Kang Young-ho didn’t usually drink and that his wife worked at Cheon Seong-gil’s house—further fueling suspicions surrounding the accident.
Meanwhile, Kwon Tae-sung was caught red-handed by Ok Seon-ja while doing the dishes to help Yoo Bo-na, who had been struggling with preparations for the ancestral rite. Ok Seon-ja cornered him, even bringing up Yoo Bo-na’s family history, but Kwon Tae-sung firmly stood his ground, saying, “Just as I am a precious son to my mother, this person is my precious wife to me.” An enraged Ok Seon-ja began throwing all sorts of food around, turning the house into a complete mess in an instant, and Yoo Bo-na was overwhelmed with mixed emotions as she watched a scene of family togetherness she had never experienced before.
Then, their daughter Kwon Yul (played by Hwang Bom-i), who had been playing at the playground, suddenly disappeared, plunging the family into chaos. Kwon Se-ah (played by Lee Eun-saem) blamed herself, recalling how she had carelessly told Kwon Yul that to go to heaven, she “had to die.” Yoo Bo-na found Kwon Yul on the apartment rooftop watching an airplane fly by, and when her daughter said, “I was going to take the plane to bring you back. ‘Because Mom’s an orphan,’” they hugged each other tightly and shed tears. The heartwarming scene between mother and daughter was deeply moving. Later, the family voted to do away with the ancestral rites, and even Ok Seon-ja agreed, adding to the warm atmosphere.
Durumi Electronics’ Sales Team 3 launched a casino operation to take down Tak Jong-gu. To gain access to the 22nd-floor VIP lounge where Tak Jong-gu was located, Ki Young-do even used special glasses designed to increase his winning odds in an effort to secure a VIP ticket. The team’s ultimate goal was to approach Tak Jong-gu, lure him out of the casino, and have Yoo Bo-na take him out.
However, an unexpected variable emerged. Just as Ki Young-do was smoothly progressing through the casino games, Moon Da-rae (played by Moon Seung-yu) burst in. “In situations like this, you have to go all in even if you can’t win. Is this your first time gambling?” Moon Da-rae taunted him, and ultimately defeated Ki Young-do to claim the VIP ticket.
As the operation fell apart toward the end of the episode, Yoo Bo-na headed to the casino herself, where Kwon Tae-sung—who had followed Cheon Seong-gil’s car—was in a scuffle with security guards. As the two people, who had come to the casino for different reasons, narrowly missed each other, the tension reached its peak. Will Yoo Bo-na be able to complete her mission without her husband finding out? The explosive ending, with the threat of “Kingfisher’s” true identity being exposed, has heightened anticipation for the next episode to the utmost.
