MBC’s new psychological thriller “The Perfect Lie,” starring Yoo Yeon-seok and Seo Hyun-jin, opened with a 1.9 percent nationwide rating on its October 30 premiere, according to Nielsen Korea figures cited by Soompi, while SBS rival “Doctor X: Mafia in White” held onto the top spot with 16.5 percent.
- Yoo Yeon-seok and Seo Hyun-jin previously co-starred in the 2016 hit 'Dr. Romantic,' according to the Korea Herald
- Their new MBC psychological thriller, 'The Perfect Lie,' was promoted at a Seoul press conference, per the Korea Herald
- The show premiered October 30 opposite SBS's 'Doctor X: Mafia in White,' as reported by Soompi
- Nielsen Korea data cited by Soompi shows 'The Perfect Lie' opened at a 1.9 percent nationwide rating
- 'Doctor X' started the second half of its run at 16.5 percent, down three points from 19.5 percent the week before, yet still topped the weekly rankings, Soompi reported
What happened
Yoo Yeon-seok and Seo Hyun-jin, who first won viewers over with their on-screen chemistry in the 2016 hit “Dr. Romantic,” are back together after ten years apart, this time in a drama built around deception and suspicion. The Korea Herald reported that the pair appeared at a Seoul press conference to introduce “The Perfect Lie,” where Yoo spoke about how naturally their old dynamic returned once filming began.
The series landed in a crowded weekend slot, going head-to-head with “Doctor X: Mafia in White,” a medical drama that has dominated ratings throughout its run, as Soompi noted. The two shows premiered their respective episodes on the same day, setting up a direct comparison in the ratings.
Why it matters
The reunion carries weight for fans who have waited a decade to see the duo share a screen again, but the numbers show how steep the competition is in Korea’s weekend drama slot. Soompi’s reporting indicates “The Perfect Lie” debuted far behind “Doctor X,” which kept its position as the week’s most-watched program despite its own viewership slipping.
Our read: a lower opening rating for a new series facing an established hit is not unusual, since established medical dramas often draw a loyal built-in audience that newer shows have to compete against from day one.
Background
“Dr. Romantic” remains a touchstone for both actors, having become a ratings smash that cemented their pairing in viewers’ minds. The Korea Herald’s coverage frames “The Perfect Lie” as a deliberate departure from that earlier medical drama, moving instead into psychological thriller territory centered on lies and mistrust between characters.
“Doctor X,” meanwhile, has built a reputation as a consistent ratings performer on SBS, according to Soompi, with its second half of episodes opening strong even as the figure dipped from the previous week’s performance.
What to watch
Whether “The Perfect Lie” can narrow the ratings gap with “Doctor X” in coming weeks will likely depend on how audiences respond to its thriller premise compared with the medical drama’s established fan base. Soompi’s report notes that “Doctor X” saw a three-percentage-point drop from its prior episode, which suggests some natural erosion in viewership as its run continues, though it still led the week by a wide margin over the new MBC series.
Industry watchers will likely track whether the Yoo-Seo pairing can build momentum through word of mouth, much as their earlier collaboration did, even though the two shows are competing in different genres and drawing from different viewer expectations.
