According to the TV buzz analysis firm Good Data Corporation’s FUNdex report, “Mary Kills People” ranked first in the TV-OTT buzz news article category following the broadcast of its first two episodes. Lead actress Lee Bo-young also secured fourth place in the TV-OTT drama actor buzz category, highlighting strong interest in both the drama and its cast.

“Mary Kills People” is a suspense drama about a doctor who assists terminally ill patients in ending their lives and the detective tracking her down. It delves into the fine line between life and death, portraying the psychological conflicts, guilt, and intertwined relationships of its characters. Fast-paced twists, layered storytelling, and emotional depth have drawn viewers in from the start.
As anticipation builds for episodes three and four, the production team has pinpointed three core reasons why the drama is a must-watch.
Immersive Performances by Lee Bo-young, Lee Min-ki, and Kang Ki-young

Lee Bo-young delivers a compelling portrayal of Woo So-jung, a doctor torn between compassion and moral conflict as she aids patients in assisted death. Lee Min-ki transforms into Detective Ban Ji-hoon, who goes undercover as terminal cancer patient Jo Hyun-woo, perfectly capturing the character’s pale complexion, stoic demeanor, and moments of agony. Kang Ki-young shines as Choi Dae-hyun, a warm yet resolute ally, balancing intense themes with empathy. Their synergy fuels anticipation for the drama’s upcoming twists and turns.
Striking Cinematography and Direction for Maximum Immersion

Director Park Joon-woo’s meticulous direction creates visually impactful scenes that heighten the drama’s emotional pull. One standout moment depicts terminally ill Lee Eun-young (Son Sook) transitioning from her daily swim to opening a door and finding herself at her chosen final resting place—the seaside—leaving a lasting impression. Another scene, where Woo So-jung confesses to Jo Hyun-woo, “I wish you could live,” captures every micro-expression and trembling gesture, amplifying the emotion. The dynamic camera work during Woo So-jung’s race to a collapsing Jo Hyun-woo further elevates the tension and audience engagement.
A Unique Blend of Medical Suspense, Human Drama, and Mystery Thriller
While centered on the suspense of a detective pursuing a doctor involved in assisted deaths, “Mary Kills People” also weaves in humanistic narratives, exploring the personal stories of those who choose to end their suffering. The drama blends mystery—such as the origin of the drugs used in assisted deaths—with backstory, including Woo So-jung’s motivation tied to her mother. These intertwined genres open new possibilities for Korean drama storytelling.

The production team stated, “Episodes 1 and 2 introduced Woo So-jung, Detective Ban Ji-hoon, and ally Choi Dae-hyun, setting the stage. From episodes 3 and 4, expect bolder developments, shocking twists, and relentless pacing. Don’t miss episode 3 airing tonight.”
With its bold premise and exceptional execution, “Mary Kills People” has quickly captivated viewers. Episode 3 airs on August 8 at 10 p.m., continuing to push the boundaries of prime-time Korean drama.
