Saturday night’s ratings battle just delivered a clear winner. MBC’s “A Bona Fide Killer” is closing in on double digits, while SBS’s “Flex x Cop 2” — airing in the very same time slot — dropped to its worst numbers across both seasons.
A Bona Fide Killer: August 14 Ratings Snapshot
| Drama | Network | Episode | Rating | Result |
|---|---|---|---|---|
| A Bona Fide Killer | MBC | Episode 5 | 9.8% | Highest of its run, #1 in time slot |
| Flex x Cop 2 | SBS | Episode 3 | 5.1% | Lowest of Season 1 & 2 combined |
Why the Gap Keeps Widening
“A Bona Fide Killer,” starring Kong Hyo Jin as a woman leading a secret double life as a hitman, took first place across all channels in its time slot on August 14 with a 9.8% nationwide rating — its best episode yet, according to Nielsen Korea. The show has been on a steady climb since debut, and it’s now knocking on the door of double-digit territory.

Meanwhile, “Flex x Cop 2,” the action-comedy sequel following the same law-enforcement-with-flair premise as its hit predecessor, slipped to 5.1% for episode three — its weakest showing yet, spanning both this season and the original. Going head-to-head with a rapidly rising competitor in the same slot clearly isn’t helping its case.
