Yoona and Lee Jin Wook are teaming up as forensic pathologists to solve cases! tvN’s new Korean drama Unnatural (tentative title) features this fresh pairing joining forces to uncover the hidden truths behind unnatural deaths. The series is scheduled to premiere in 2027.
Set in the fictional forensic autopsy and identification institute “U.D.I.” under the National Institute of Scientific Investigation, Unnatural is a medical mystery drama adapted from the 2018 Japanese TBS hit series of the same name. The original Japanese drama starred powerhouse actress Satomi Ishihara and swept six major awards—including Best Drama—at the 96th Television Drama Academy Awards, establishing a loyal fan base in South Korea as well. The Korean remake will be written by screenwriter Min Ji-eun and directed by director Park Yoo-young.

Female lead Yoona plays Song Do-eun, a forensic pathologist at the U.D.I. Center. Appearing calm and collected on the outside, she harbors a deep sense of compassion and tenacity beneath her surface, remaining unfazed in front of any body. Behind her steadfast dedication lies a warm desire to listen to the final voices of the deceased. Yoona has recently proven herself as a reliable box-office and ratings guarantee; her previous tvN drama Bon Appétit, Your Majesty achieved a peak rating of 17.1%, marking tvN’s highest drama viewership record in 2025. Her performance in tackling the forensic genre this time is eagerly anticipated.

Lee Jin Wook plays fellow forensic pathologist Goo Seung-hyuk. Cold to the point of being ruthless, he maintains an expressionless demeanor and keeps his distance from the living, showing interest only in the dead—earning him the nickname “Grim Reaper Hyuk.” However, his expertise is unmatched; with a career spanning over 3,000 autopsies, he completes procedures swiftly without missing even the smallest detail. Having previously played detectives and lawyers pursuing the truth, Lee Jin Wook will now investigate cases starting from the traces left behind by death.

The production team expressed complete confidence in Yoona, stating, “Her warm, bright energy paired with Song Do-eun’s inner resilience and human charm will create fantastic synergy.” Regarding Lee Jin Wook, they noted, “His signature chilly aura and restrained emotional delivery will blend seamlessly with the guarded character of Goo Seung-hyuk.” Unnatural will premiere in 2027.


If you loved the emotional depth and subtle warmth beneath the scalpel in the original Unnatural, the Korean remake pairing Yoona with Lee Jin Wook is already a must-watch. For fans eager to see Yoona build on her explosive momentum from Bon Appétit, Your Majesty, this medical mystery drama is a mandatory addition to your 2027 watchlist.
