Cardiothoracic surgeon Min Joon-ho and elementary school librarian Kang Ji-seon find their romantic first date upended by a shocking sexual assault report in MBC’s psychological thriller series The Perfect Lie, which premiered on television across South Korea on October 30, 2026.
Ten years after sharing the screen in the medical drama Dr. Romantic, actors Yoo Yeon-seok and Seo Hyun-jin are back together in an entirely different narrative landscape. Directed by Jo Young-min and written by Baek Jae-young, the MBC Friday-Saturday drama kicked off its run with a 1.9 percent national household viewership rating, alongside a peak metropolitan rating of 4.8 percent.
Min Joon-ho and Kang Ji-seon Collide Over Conflicting Memories
The story opens with an unexpected encounter. Kang Ji-seon, working as an elementary school librarian, and cardiothoracic surgeon Min Joon-ho meet through a misunderstanding. After running into each other again under circumstances shaped by fate, Kang accepts an invitation for a first date that begins smoothly, with Min showing a seasoned yet slightly clumsy charm.
Following their outing, a torrential downpour prompts Kang to invite Min inside her home to wait out the rain. The next morning diverges sharply for the two characters. While Min arrives at his hospital workplace in a cheerful mood fueled by the previous night, Kang wakes up in distress, collapses into tears, visits her older sister Kang Ji-eun—played by Kim Ji-hyun—and ultimately reports Min to the police for sexual assault.

A Truth Game Built on Contradictory Testimonies
From that police station report onward, the narrative pivots into a psychological clash where both characters offer diametrically opposed accounts of the same evening. Min maintains that there was no coercion whatsoever, whereas Kang insists the act occurred entirely against her will. The two even present conflicting memories regarding who initiated their kiss.
The premiere episode concludes with a dramatic scene featuring a kiss, leaving audiences with a central mystery: which of the two protagonists is telling the truth, and who is lying? Director Jo Young-min noted that both actors bring deep emotional nuance to roles designed around suspicion and shifting perspectives.
We know each other so well that working together was genuinely thrilling and exciting.
