Mary Kills People will air its final episode on September 12, 2025, bringing the Korean drama adaptation to a dramatic close. The series, which stars Lee Bo-young, Lee Min-ki, and Kang Ki-young, follows a doctor secretly providing euthanasia to terminally ill patients while being pursued by law enforcement. The finale is expected to resolve ongoing conflicts, including the return of a vengeful character and the moral dilemmas surrounding assisted dying.
Final Episode Release Schedule
The last episode of Mary Kills People will broadcast on September 12, 2025, at 10 pm KST on MBC TV. This scheduling follows the pattern of previous episodes, which aired every Friday and Saturday. Episodes 10 and 11 were shown on September 5 and 6, setting the stage for the series conclusion. The show is also available on streaming platforms, though specific details have not been officially confirmed yet .
Expected Plot Developments For The Finale
The finale will focus on Go Ha-rin, the sister of deceased antagonist Go Gwang-cheol, who returns seeking revenge against Dr. Woo So-jeong. Ha-rin approaches So-jeong at the church hospital under the false pretense of donating supplies but quickly reveals her true intent. She blames So-jeong for her brother’s death and demands a business partnership similar to the one he had with the doctor. So-jeong denies any partnership with Gwang-cheol and refuses Ha-rin’s offer, leading to threats and increased tension.
Another key plot point involves an elderly woman who approaches So-jeong requesting euthanasia. This creates a new moral challenge for the doctor, who had previously resigned from her hospital job and joined a church hospital to abandon euthanasia. However, it is revealed that she has secretly resumed her assisted dying activities. Detective Ban Ji-yoon informs So-jeong about this new case, and Choi Dae-hyeon comments that some people genuinely need such help. The finale will determine whether So-jeong escapes Ha-rin’s revenge or gets arrested in the process .
Background Of The Series
Mary Kills People is a Korean remake of the Canadian drama with the same name that aired from 2017 to 2019. The Korean version is written by Lee Soo-ya and directed by Park Joon-woo. It features Lee Bo-young as Dr. Woo So-jeong, a respected emergency medical doctor who leads a double life providing illegal euthanasia. Lee Min-ki plays Cho Hyeon-woo, a terminally ill patient who transforms after meeting So-jeong, and Kang Ki-young portrays Choi Dae-hyeon, her partner in assisted dying .
The series explores complex themes such as moral ambiguity, life and death decisions, and the psychological impact of assisted dying on those who provide it. It has blended elements of psychological drama, romance, investigative thriller, and action throughout its run. The show began airing on August 1, 2025, and consists of 12 episodes .
Major Events Leading To The Finale
Episodes 10 and 11 included significant developments that set the stage for the finale. In episode 10, Choi Dae-hyeon betrayed Go Gwang-cheol by cooperating with the police, leading to a failed attempt to arrest him. So-jeong was involved in a euthanasia case for Park Tae-hyung and his wife Bae Min-young, which ended in tragedy when Min-young jumped from a balcony after her husband’s death. However, she survived the fall and was admitted to So-jeong’s hospital, where Park Min-seong later suffocated her to death.
Dae-hyeon was attacked by Go’s men after attempting to trap him, and So-jeong proposed a partnership with Go, which he accepted. Episode 11 featured a time jump of three years after several arrests. Go Gwang-cheol was shot by Detective Ban Ji-yoon, and Park Min-seong was arrested for attempting to kill Min-young. Evidence found at Go’s house led to the arrest of An Tae-seong. Dae-hyeon took the blame for the euthanasia activities to protect So-jeong, who then resigned from her hospital and joined a church hospital. However, she secretly resumed her euthanasia work, which sets the context for the finale’s conflicts .
Production And Cast Details
The drama is produced by MBC and features a strong ensemble cast. Lee Bo-young plays the lead role of Woo So-jeong, a doctor grappling with the moral implications of her actions. Lee Min-ki portrays Cho Hyeon-woo, a patient who becomes involved in her secret work. Kang Ki-young appears as Choi Dae-hyeon, So-jeong’s partner in assisted dying who faces his own legal and ethical challenges. Supporting cast members include Kang Na-eon as Yu-mi and Kwon Hae-hyo as Father Yang .
The series is based on the Canadian show created by Tara Armstrong, which ran for three seasons from 2017 to 2019. The Korean adaptation has been noted for its intense storytelling and strong performances, particularly from Lee Bo-young, who brings depth to her character’s internal struggles .
Viewer Expectations And Speculations
Fans expect the finale to address whether So-jeong will be able to continue her work without legal consequences or if she will face arrest. The role of Detective Ban Ji-yoon remains crucial, as he has been investigating So-jeong while also showing understanding toward her motives. The return of Go Ha-rin adds a new threat, and her demand for a partnership could lead to dangerous situations. The elderly woman’s request for euthanasia might force So-jeong to reconsider her choices and reveal her secret activities to the church or authorities.
The relationship between So-jeong and Dae-hyeon is another point of interest. Dae-hyeon has just been released from jail at the end of episode 11, and his involvement in the finale could influence the outcome for So-jeong. His willingness to sacrifice himself for her suggests that he might play a key role in resolving the central conflict .
