MBC’s upcoming Friday-Saturday drama Mary Kills People is already getting attention. And not just because of the cast. The story is hard to ignore.
This sensitive subject matter places the drama firmly within current global debates on end-of-life care and patient autonomy. While euthanasia remains illegal in South Korea (as in many countries), public discourse and legal challenges surrounding “death with dignity” have been growing, mirroring trends seen in nations like Canada (home of the original) and parts of Europe and the US. The drama enters a complex, real-world conversation.
It follows Woo So-jeong (played by Lee Bo-young), a doctor who secretly helps terminally ill patients end their suffering. What she’s doing is illegal. But to her, it’s mercy. She’s not alone. Dr. Choi Dae-hyeon (played by Kang Ki-young) works beside her. Together, they cross a very thin line.
There’s a twist. Detective Cho Hyeon-u (played by Lee Min-ki) is tracking them down. He wants to stop them. But he’s also dying. He has a brain tumor. That fact changes everything. He’s the hunter and also the one being hunted by fate. This drama is a remake of the Canadian series of the same name. But this version isn’t just a copy. It’s been reimagined for Korean viewers. And with a cast like this, it might dig even deeper.
Lee Bo-young is making a return to MBC after 13 years. Her new role is a shift. She’s usually calm, but here, she plays someone who’s desperate, conflicted, and haunted by every decision. The teaser clip shows her in several intense scenes — sometimes scared, sometimes defiant, always torn.
A Story That Feels Personal, Even If It’s Fiction
The long-tail keyword “Mary Kills People Korean drama remake” fits this show well. And for people searching for something bold and serious, this drama might stand out. Especially with themes like assisted dying, moral boundaries, and human rights — issues that don’t show up often in K-dramas.
This story isn’t just about helping the sick. It’s about guilt, control, and how good intentions can go wrong. The teaser shows Woo So-jeong being accused of turning death into a business. A character named Koo Gwang-cheol (played by Baek Hyun-jin) calls her work “euthanasia.” It’s not an accusation. It’s a warning.

Choi Dae-hyeon, her medical partner, says something else. He believes that maybe — just maybe — death can become a right, not just an end. This perspective, advocating for patient autonomy at the end of life, is central to real-world organizations like Dignitas or arguments in places where assisted dying is legal. However, the drama also introduces the counterpoint accusation of turning death into a “business,” highlighting fears of coercion, slippery slopes, and the potential devaluation of life that opponents emphasize. He doesn’t say much, but what he says lingers.
The teaser continues with eerie moments. There’s tension. Someone points a gun. Someone else takes a photo. There’s a woman screaming in the wind. And there’s a voice whispering, “Do just as I say.” Nothing here feels safe or clear. That’s probably the point.

Lee Bo-young, Lee Min-ki, and a Risky Premise
The cast is a big reason this remake has people talking. Lee Min-ki plays Cho Hyeon-u, a detective who is dying. That irony isn’t lost on anyone. He’s supposed to stop Woo So-jeong. But maybe he also wants her help. We don’t know yet.
Kang Ki-young takes a quieter role here, but early footage shows he has a big impact. His character seems to understand the pain that brings people to this choice. Whether he agrees or not, we’ll find out later. The director is Park Joon-woo, known for Taxi Driver and Crash. His style is fast, sharp, and emotional. Writer Lee Soo-ah is also involved. Her past work focused on real-world pain and empathy. Both seem like a good match for this story.
The drama starts airing on August 1, 2025, and will run for 12 episodes. It airs every Friday and Saturday on MBC. Again, the “Mary Kills People Korean drama remake” keyword is likely to gain more traction once it starts airing. Especially with such layered characters and moral tension.
There’s another layer to all this. The teaser hints that someone is watching Woo So-jeong. A camera flashes. A microwave explodes. There’s smoke. Danger. Not from the police — but maybe from someone else who knows what she’s doing. Maybe someone inside the system. Or outside.
At one point, a woman smiles at Woo So-jeong in a way that doesn’t feel friendly. That moment could mean nothing. Or everything. The drama asks hard questions. Can a doctor play God? Is pain enough reason to choose death? When laws and compassion clash, who wins?
This isn’t just a medical drama. It’s also crime, suspense, and personal collapse. There’s no easy answer in Mary Kills People. And that’s exactly why it could stand out. This show will likely keep people divided. Some might agree with Woo So-jeong. Others may not. But either way, they’ll want to see what happens next. The Mary Kills People Korean drama remake doesn’t try to please everyone. It just tells a story about death, pain, and the people left behind.
