Best Korean Dramas H1 2026

2026 First-Half K-Drama Wrap-Up: Six Months by the Numbers

The first half of 2026 saw terrestrial networks make a long-awaited comeback in Korean television. Two MBC Friday–Saturday dramas dominated the top of the ratings chart, a JTBC Saturday–Sunday series surged alongside them in its finale, and tvN commanded online buzz. A Netflix original also claimed the top spot in domestic buzz rankings.

This review breaks down the first half of the year across two key metrics: ratings and buzz. Ratings are based on Nielsen Korea nationwide figures, while buzz rankings follow the weekly integrated TV/OTT Fundex metrics by Good Data Corporation. These two indicators often diverge, and where they part ways reveals a great deal about the character of each show.

1. Top 5 Dramas by Viewership Ratings

All five series aired in Friday–Saturday or Saturday–Sunday prime-time slots, proving that weekend nights remain the true home turf of Korean television. Rookie Employee Chairman Kang premiered during the first half of the year and concluded on July 5, so its finale record is included here.

2. #1 — Perfect Crown

Starring IU and Byeon Woo-seok, this MBC Friday-Saturday drama claimed the top spot for the first half of the year, wrapping up with a nationwide viewership rating of 13.8% for its finale.

It was equally dominant in buzzworthiness. In early April (Week 14), IU ranked #1 on Good Data Corporation’s buzzworthy TV cast rankings. Sweeping both high ratings and viral buzz, it stands as the definitive hit of the first half of the year. You can listen to the OST sung by KiiKii at Go On.

3. Tied for No. 2: Judge Lee Han-young

A real-time peak of 17.2% highlights the defining trait of this drama: viewers locked in for high-tension scenes, a pattern typical of gripping suspense thrillers. Pulling off numbers like this in a January kickoff slot is an exceptional feat.

4. No. 4: Undercover Miss Hong

Although fourth in viewership, it dominated online buzz in the early part of the year. In early February (Week 6), it clinched the top spot on Good Data's integrated drama buzz chart, leading a tvN sweep where the network occupied three spots in the top 10.

Its greatest asset was its premise: an office comedy set against the backdrop of Yeouido in the late 1990s. The turn-of-the-millennium corporate culture turned out to be prime comedic fodder while serving up a rich dose of nostalgia.

5. Late Bloomers & Streamers: Rookie Employee Chairman Kang, Brave New World, and OTT

Rookie Employee Chairman Kang (JTBC Sat–Sun) gained momentum as it progressed toward its conclusion. Its July 5 finale scored personal-best ratings of 13.6% nationwide and 13.5% in the capital area, peaking at 14.8% on a minute-by-minute basis. Starring Son Hyun-joo and Lee Jun-young, its polarizing ending left viewers divided.

Brave New World (SBS Fri–Sat, 14 episodes) hit its own series high in its June 20 finale, posting 11.8% nationwide and a real-time peak of 14.1%. After premiering in the 4% range, it broke the 10% barrier in just six episodes. Lead actress Lim Ji-yeon topped the drama performer buzz rankings in mid-June (Week 25). The fact that the fifth-rated drama commanded the top buzz slot at that point demonstrates just how much steam it gathered toward its run's end.

On the streaming side, Netflix original Bloodhounds Season 2 topped Good Data’s drama buzz rankings in early April (Week 14) with a commanding 21.20% share. Outranking broadcast dramas on the same integrated chart was a notable milestone.

6. Where Ratings and Buzz Diverged

Ratings count the people tuning in live, while buzz counts the people talking about the show. Terrestrial weekend dramas dominated viewership ratings, while tvN and Netflix took the lead in viral buzz—a dynamic that played out repeatedly throughout the first half of the year. Looking at only one of these metrics leaves you with half the picture.

9. Key Takeaways

The first half of 2026 saw Perfect Crown (MBC Fri–Sat, 13.8% finale) take the ratings crown, followed by a tie for second place between Judge Lee Han-young (13.6%, real-time peak 17.2%) and Rookie Employee Chairman Kang (13.6%, wrapped July 5), with Undercover Miss Hong (13.1%) close behind. In buzz rankings, Undercover Miss Hong dominated early February, Bloodhounds Season 2 swept early April, and Brave New World peaked in mid-June.

Looking back across the six months, the division of influence was clear: terrestrial weekend slots commanded the ratings, while cable and OTT captured the conversation. Check only the TV ratings and you miss the impact of tvN and Netflix; check only the buzz charts and you overlook the staying power of MBC's weekend lineup.
