The Perfect Lie brings Yoo Yeon Seok and Seo Hyun Jin back together on screen for the first time in a decade, this time as two people who remember the same night in completely different ways. The MBC psychological thriller premieres October 30, 2026, runs for 12 episodes through December 5, 2026, and streams globally on Disney+ while airing on Wavve inside Korea. Fans of Dr. Romantic have waited ten years for this reunion, but the romantic glow from that 2016 medical drama is gone. What replaces it is a tense question: who is lying?

When Does The Perfect Lie Premiere and How Many Episodes Are There
The Perfect Lie premieres on Friday, October 30, 2026, at 9:50 PM KST on MBC. The drama airs two episodes per week, every Friday and Saturday, across a six-week run. The twelfth and final episode is scheduled for Saturday, December 5, 2026. That gives the series a total of 12 episodes, a standard count for MBC’s Friday-Saturday prime-time slot.
For global viewers, the release pattern matters. Episodes drop on Disney+ for international audiences, while Korean viewers can also stream on Wavve. Disney+ availability covers regions including the USA, UK, Canada, Australia, India, and most major markets where the platform operates. The Disney+ release typically follows the Korean broadcast closely, though the exact timing varies by region.
The UK original Liar ran for six episodes in 2017. The Korean adaptation expands that story to 12 episodes, which means the writers have room to deepen the psychological duel between the two leads and give supporting characters more room to breathe.
Who Is in The Perfect Lie Cast and What Roles Do They Play
Yoo Yeon Seok leads as Min Jun Ho, a cardiac surgeon and single father described as someone “trusted by everyone.” His character is calm under pressure, which makes his version of events sound reasonable until it does not.
Seo Hyun Jin plays Kang Ji Sun, an art teacher at a middle school who meets Jun Ho through his son’s school. She becomes the emotional counterweight to his composure, insisting that something terrible happened and that Jun Ho is the one lying about it.
The supporting cast includes Ok Ja Yeon as Lee Hwa Young, a detective in the Women and Juvenile Affairs Division who is connected to both leads through personal ties. Im Sung Jae plays Park Seok Gu, Hwa Young’s husband and a UDT/SEAL officer. Kim Jihyun appears as Kang Ji Eun, Ji Sun’s older sister and an anesthesiologist, while Lee Chun Hee plays Kim Hyung Soo, Ji Eun’s husband and Ji Sun’s brother-in-law.
This is a tight ensemble. Six named characters, each with a direct link to the central mystery. That structure keeps the story focused on the question the teaser asks: “Who is the liar?”
Where You Have Seen the The Perfect Lie Cast Before
Yoo Yeon Seok has built one of the most varied careers in Korean television. He made his screen debut in Park Chan Wook’s Oldboy (2003) as the younger version of Lee Woo Jin. Television audiences know him from Reply 1994 (2013), Dr. Romantic (2016), Mr. Sunshine (2018), Hospital Playlist (2020–2021), and When the Phone Rings (2024). His recent work includes Phantom Lawyer, and he has consistently moved between romance, medical dramas, and darker roles.
Seo Hyun Jin first gained wide recognition through Another Miss Oh (2016) and Dr. Romantic (2016), the same year she worked opposite Yoo Yeon Seok. Her later credits include The Beauty Inside (2018), Black Dog (2019), You Are My Spring (2021), and The Trunk (2023). She most recently starred in Love Me (2025).
Ok Ja Yeon has appeared in Burning (2018), Ashfall (2019), Mine (2021), Big Mouth (2022), and Under the Queen’s Umbrella (2022). She also appeared in Gyeongseong Creature.
Im Sung Jae is known for Extraordinary Attorney Woo (2022), The Worst of Evil (2023), Black Knight (2023), and Moving (2023). He has become a reliable presence in supporting roles across genre dramas.
Kim Jihyun appeared in Thirty-Nine (2022) as Jang Joo Hee, among other television roles.
Lee Chun Hee debuted in the film A Good Lawyer’s Wife (2003) and became widely known through the variety show Family Outing in 2008. His drama credits include Conspiracy in the Court (2007), King Sejong the Great (2008), and Law School (2021).

What The Perfect Lie Is About and How It Connects to the UK Original
The Perfect Lie follows Min Jun Ho and Kang Ji Sun after a first date that seems to go perfectly. The next day, their accounts of what happened diverge completely. One insists something criminal occurred. The other calls it a misunderstanding. The police get involved, and the drama becomes a psychological battle over a single memory.
The series is a Korean adaptation of Liar, a UK drama that aired on ITV in 2017. The original was created by Harry and Jack Williams and produced by Two Brothers Pictures. Kakao Entertainment secured the remake rights from All3Media International, and the Korean version is co-produced by Kakao Entertainment and Zip Cinema (also known as Film Company Jip).
Director Jo Young Min previously worked on You and Everything Else and Love Me. Writer Baek Jae Young penned the adaptation. The production wrapped filming in August 2026, giving the team roughly two months of post-production before the October premiere.
The central hook is simple and brutal: two people share one night, and only one version can be true. The teaser shows Seo Hyun Jin’s character saying, “Overnight, the whole world changed like a lie,” before cutting to both leads in a police interrogation room, each refusing to back down.
Where to Watch The Perfect Lie Globally
Korean viewers can watch The Perfect Lie on MBC at 9:50 PM KST on Fridays and Saturdays, with streaming available on Wavve.
International viewers can stream the drama on Disney+. The platform holds the global distribution rights and will make episodes available in the USA, UK, Canada, Australia, India, and other major markets. Disney+ has an output deal with MBC that gives the streamer first option on the network’s dramas. The partnership previously delivered Perfect Crown, which became Disney+’s most-watched South Korean series globally with over 43 million viewing hours.
Netflix is not the streaming home for this Korean drama. Some listings for a Dutch series also titled The Perfect Lie exist on Netflix, but that is a separate production based on the novel The Dinner Club by Saskia Noort. The Korean The Perfect Lie streams exclusively on Disney+ internationally.
The Perfect Lie arrives with the weight of a ten-year reunion behind it, but the drama itself is built on a single unnerving question that neither the cast nor the teaser answers.
