K-Drama Ratings Battle: “Climax” Surges Into Its Second Half While “Siren’s Kiss” Races Toward a Gripping Finale

Two of the hottest K-dramas airing right now are making serious noise in the ratings — and if you’re not watching both, you’re genuinely missing out. Here’s everything you need to know about where things stand.

K-Drama Ratings Snapshot — March 31, 2026

“Climax” Is Heating Up Right When It Matters Most

The suspenseful drama starring Ju Ji Hoon and Ha Ji Won enjoyed a modest increase in viewership ratings as it kicked off its second half, with episode 6 scoring an average nationwide rating of 3.5 percent according to Nielsen Korea.

A ratings bump heading into the second half is exactly the kind of momentum a thriller needs. With two powerhouse leads and an increasingly tense storyline, “Climax” is clearly building toward something big. If you haven’t started it yet, now is the perfect time to catch up before the final episodes drop.

Nielsen ratings remain one of the most trusted benchmarks for measuring television viewership, and a consistent rise mid-series is a strong indicator of growing audience investment.

“Siren’s Kiss” Owns Its Time Slot Heading Into the Finale

tvN’s “Siren’s Kiss,” the romance thriller starring Park Min Young and Wi Ha Joon, took first place in its time slot across all cable channels, earning an average nationwide rating of 4.4 percent — with just two episodes remaining.

That’s a remarkable position to be in with the finish line in sight. Park Min Young and Wi Ha Joon’s on-screen chemistry has clearly resonated with viewers week after week, and a 4.4% cable rating in today’s fragmented streaming landscape is genuinely impressive.

The big question now: will the finale deliver the payoff fans have been waiting for?
