Actress Lee Bo Young, who is married to fellow actor Ji Sung, shared her heartfelt thoughts as Mary Kills People aired its final episode.

The suspense drama, which revolves around a doctor assisting terminally ill patients with euthanasia and a detective who begins investigating the mysterious cases, started with a 3.2% rating but dropped to 1.1% by its conclusion. Despite the decline, the cast offered gratitude and personal reflections on the story’s impact.

Portraying Woo So Jung, a doctor who both saves lives and aids in assisted deaths, Lee Bo Young said, “I hope viewers could reflect deeply on the theme of death and the final moments with family—something we often see as distant. This project made me ask myself many questions. It wasn’t about deciding if assisted dying is right or wrong, but about giving time to think about it personally. If the drama allowed that space, I’m truly grateful.”

She chose her debate scene with Father Yang as the most memorable moment, noting it helped her understand multiple perspectives on assisted dying: “It showed me there are many ways of looking at this issue, and that process itself was meaningful.”

Lee added that she never wanted So Jung to be framed in absolutes—right or wrong, good or bad. Instead, she hoped viewers would decide for themselves, emphasizing that the drama’s point was to leave room for reflection rather than present fixed answers.

Co-star Lee Min Ki, who played detective Ban Ji Hoon, also expressed thanks to viewers. He highlighted lines such as, “Why do you do this—helping people die?” and “You’re destroying yourself while saving others”, saying they revealed Ban Ji Hoon’s humanity behind his rigid sense of justice.

Actor Kang Ki Young, praised for his warmth and conviction as a doctor supporting patients, thanked viewers for embracing such a challenging topic. He reflected, “It made me think again about human dignity. Since life is finite, I only hope everyone’s partings can be less painful.” He recalled a line that stuck with him: “In time, it might simply be a matter of choice or even a right.” For him, it underscored the ongoing importance of public discussion on the subject.

The production team praised the three leads for bringing depth and weight to the drama, stating, “Lee Bo Young, Lee Min Ki, and Kang Ki Young elevated the value of Mary Kills People with their powerful performances.”
