“A Bona Fide Killer” Wraps Up: Kong Hyo Jin, Jung Jun Won & Lee Sang Yi Reflect on Their Final Bow

Every great K-drama run eventually has to end, but not every ending goes out on top. MBC’s “A Bona Fide Killer” managed exactly that, closing its story on September 13 with the highest viewership ratings of its entire run. As the credits rolled, its three leads took a moment to look back on the journey and thank the fans who carried them there.

Here’s a full breakdown of what the cast had to say, and where you can catch up on the series if you haven’t started yet.

A Bona Fide Killer: Drama Wrap-Up

Kong Hyo Jin Reflects on Stepping Into a New Kind of Role

Kong Hyo Jin, who played Yu Bo Na, described the project as one that pushed her toward new creative territory and left her genuinely moved by how warmly viewers responded to the hard work behind it. She expressed hope that the experience stays a cherished memory for the entire cast and crew who spent months bringing the story to life together, thanking everyone involved once more.

She also spoke directly to fans, noting that many viewers discovered a different side of her through Yu Bo Na, and asked them to stay tuned for the other facets of herself she plans to reveal in future projects.

Jung Jun Won Calls the Experience “Especially Precious”

Jung Jun Won echoed a similar sentiment, saying he felt fortunate to be part of a production this strong and expects the memory to stay with him well after the show’s run has ended. He credited the experience with real personal and professional growth, calling it one of the more meaningful chapters of his career so far. He closed out his message by thanking fans who connected with the story and laughed along the way, promising to return with another strong performance down the line.

Lee Sang Yi Bids Farewell to Detective Dong Jin

Rounding out the cast’s goodbyes, Lee Sang Yi reflected on wrapping a project he genuinely enjoyed filming, describing “A Bona Fide Killer” as a story built around a relentless, never-ending chase. He thanked fans for supporting the drama throughout a particularly hot summer season and offered a lighthearted nod to his character, Dong Jin, joking that the detective will likely keep chasing leads without ever slowing down — much like the energy he hopes viewers carry with them too.

Why the Finale Ratings Matter

A drama closing out on its best ratings yet is no small feat — it typically signals strong word-of-mouth momentum and a fanbase that grew more invested as the story progressed rather than losing steam. For “A Bona Fide Killer,” ending on a high note also sets up a strong afterlife for the series on streaming, where new viewers often discover a show based on how well its ending was received.
