“The Perfect Lie” just posted its best numbers yet, but “Doctor X” is still the show to beat on Friday nights. The two dramas air in the same time slot on MBC and SBS, and the ratings gap between them tells a story about star power, controversy, and what viewers are actually tuning in for.
The Numbers: A Small Rise vs. a Steady Reign
“The Perfect Lie” climbed to an average nationwide rating of 2.2 percent for its third episode on November 6, according to Nielsen Korea. That is up from the 1.9 percent pulled by both of its first two episodes. The episode also hit a peak minute of 4.2 percent, marking the first time the drama has moved into the 2 percent range.
“Doctor X” stayed on top with an average nationwide rating of 15.3 percent for its ninth episode, also aired on November 6. The episode peaked at 16.6 percent and kept the SBS drama at No. 1 in its time slot for the fifth consecutive week across all channels. Among viewers aged 20 to 49, a key group for advertisers, “Doctor X” averaged 5.3 percent with a peak of 5.86 percent.
The gap is wide: 15.3 percent versus 2.2 percent is not a close race. But the two shows are playing different games. “Doctor X” is a mass-audience medical thriller with a major star. “The Perfect Lie” is a darker psychological drama about a contested night between two people, and it is building slowly from a low base.

Why “Doctor X” Keeps Winning Despite Controversy
“Doctor X: Mafia in White” has held the No. 1 spot for five straight weeks, but its path has not been smooth. The drama, which stars Kim Ji-won as a genius surgeon nicknamed “the madwoman of the operating room,” has faced two major pushbacks.
Medical professionals filed a petition with the Korea Communications Standards Commission, arguing the series simplifies the medical field into “incompetent villains” and ignores the real uncertainties of medical practice. A separate controversy erupted over Episode 6, which touched on the May 18 Gwangju Democratization Movement. A petition calling for the show’s suspension was submitted through the National Assembly’s public petition system and passed the initial supporter threshold.
Ratings did take a hit. After hitting a series high of 19.5 percent with Episode 6, the show has not crossed the 20 percent mark. Episode 7 drew 16.5 percent, Episode 8 drew 15.6 percent, and Episode 9 settled at 15.3 percent. The slip is real, but the show is still far ahead of everything else in its slot.
What keeps viewers coming back? The Episode 9 twist gave the show a fresh jolt. Lee Jung-eun, who plays Jang Hee-sook, walked into the operating room and revealed herself as Gye Su-jeong’s (Kim Ji-won) former mentor. The moment turned a solo, impossible surgery into a master-pupil team-up and gave the show its most talked-about scene of the week.
Jang Hee-sook replied, “If a doctor who prioritizes the patient’s life and well-being above all else and gives their all to every surgery they perform is Doctor X, then Gye Su-jeong is indeed Doctor X.”
That answer landed with viewers. The mentor reveal gave the show a reason to push past the controversy noise and focus on the story again.
Why “The Perfect Lie” Is Rising, Just Slowly
“The Perfect Lie” is a different kind of show. It follows Min Joon-ho (Yoo Yeon-seok), a cardiovascular surgeon and single father, and Kang Ji-sun (Seo Hyun-jin), a school teacher, who give completely opposite accounts of the same night. A polygraph test points to an unexpected person, and the drama turns into a tense “she said, he said” psychological thriller.
The drama is a remake of the 2017 British series “Liar”, and it carries heavy material. A content warning for references to sexual assault accompanies early episodes, and the story is not built for easy viewing. That tone may explain why the ratings started low and are climbing in small steps rather than surging.
The rise from 1.9 percent to 2.2 percent is modest, but it is still a rise. Episode 3 pushed the story into a more active phase: Ji-sun sneaks into Joon-ho’s house to look for evidence, and the power dynamic between the two characters shifts. The production team teased that the truth battle between the two leads “officially begins” in Episode 3, and the psychological war between them intensifies.
The drama also has a built-in hook for Korean audiences: it reunites Yoo Yeon-seok and Seo Hyun-jin for the first time in 10 years, after they starred together in “Dr. Romantic.” The two actors have spoken openly about how that history helped them through the emotionally difficult scenes.
Yoo Yeon Seok said, “Although we met again after 10 years, it felt more welcoming and comfortable than unfamiliar. Because we trust each other, we were able to lean on one another and draw acting energy from each other while filming scenes that were emotionally challenging.”
Seo Hyun Jin added, “At first, there were moments when I thought, ‘He’s changed so much,’ which made watching Yoo Yeon Seok’s performance so much fun. As filming progressed, I found it enjoyable and comfortable to act alongside him because I could trust him.”
That trust shows on screen. Critics have noted that the two leads carry the show’s tense, uncomfortable material with a level of comfort that makes the clash between their characters feel real rather than forced.
What Netizens Are Saying About Both Shows
Reactions to “Doctor X” are split. The show has a loud fan base that celebrates Kim Ji-won’s performance and the master-pupil twist, but it also has vocal critics. Viewers on Reddit and X have questioned the medical logic of Episode 9, where Su-jeong performs an ex vivo multivisceral autotransplantation — a procedure that removed six organs, excised tumors from each, and reimplanted them — in roughly 15 hours. In real life, the surgeon who pioneered the procedure took about 23 hours, and some viewers found the compressed timeline unrealistic even for fiction.
The May 18 Gwangju storyline also drew a mixed response. Some overseas viewers said the episode moved them to tears and prompted them to learn more about Korean history, while domestic petitioners demanded the show be taken off air.
For “The Perfect Lie”, the conversation is quieter but focused on the performances and the show’s uncomfortable subject matter. The drama comes with a clear content warning, and some viewers have noted that the material may be difficult for anyone who has been through something similar. The slow ratings climb suggests the show is finding its audience week by week rather than grabbing a mass audience on premiere night.

The Bottom Line on Friday Night Ratings
“Doctor X” is still the ratings king, but its reign is no longer growing. The show hit 19.5 percent with Episode 6 and has been sliding since, even as it holds No. 1. The controversy over medical accuracy and the Gwangju storyline has cost it momentum, and the 20 percent barrier that once looked close now feels further away.
“The Perfect Lie” is not close to catching “Doctor X” in raw numbers, and it is not trying to. The MBC drama is a slower, darker character study that is building from a small base. The rise to 2.2 percent is the first sign that the show is finding traction, and the reunion of its two leads gives it a clear identity that stands apart from the medical thriller in the same slot.
