The Korean drama ratings war just got spicy. Two shows, the same number — but one is celebrating while the other is quietly panicking.

Same Number, Opposite Stories
It’s rare that two dramas share the exact same rating in a single week — but what makes this moment truly fascinating is what that 3.9% means for each show.
According to Nielsen Korea, the third episode of “Climax” scored an average nationwide rating of 3.9 percent — marking an all-time high for the new ENA series starring Ju Ji Hoon and Ha Ji Won. Wikipedia That’s a promising upward climb for a show still finding its footing on a smaller network.
On the flip side, tvN’s “Siren’s Kiss” also recorded a 3.9 percent average nationwide rating as it kicked off the second half of its run — but this figure marked an all-time low for the romance thriller, which had premiered to a much stronger 5.5 percent and had since lingered in the 4 percent range.

That’s a dramatic fall from grace for a show that launched with serious buzz.
Why “Climax” Is Winning Hearts
Ju Ji Hoon and Ha Ji Won are a proven pairing that fans already trust. ENA, while not as large as tvN, has been building credibility with quality productions. A steady episode-by-episode ratings climb is often more sustainable than a big premiere followed by a drop — and right now, “Climax” is showing exactly that kind of momentum.
Korean television ratings, measured by Nielsen Korea, reflect nationwide audience share — making even a 3.9% score meaningful in today’s fragmented streaming landscape. Learn more about how television ratings systems work on Wikipedia.
