Four Hands, Two Sonatas Debuts at No. 1 as New Dramas Reshape the K-drama Buzz Rankings
Four Hands, Two Sonatas debuted at No. 1 in Good Data Corporation’s latest TV-OTT drama buzz rankings, updated on September 1, 2026. The tvN music drama captured 20.73% of the week’s Buzz Share, while its leads Lee Jun-young and Song Kang took the top two positions in the performer ranking.
New Recruit 4: Sabotage climbed six places to No. 2 with 16.94%, and Mousetrap rose four places to No. 3 with 14.77%. A Love Other Than Yours entered at No. 8 ahead of its premiere, while The Affair Was Just the Beginning re-entered at No. 10.
Spooky in Love, which led last week, dropped out of the Top 10 after completing its run. Dream to You and Our Sticky Love also left the table.
Unlike television ratings, the FUNdex rankings measure online conversation across news articles, blogs, social media, online communities, and video platforms, providing a snapshot of which dramas audiences are talking about most.

Note: FUNdex measures online discussion rather than television ratings or streaming views. Dramas and performers may appear based on buzz generated by trailers, promotional events, casting news, interviews, and other online activity, including before a drama officially premieres. 🆕 New means new to this week’s Top 10 table, not necessarily a newly released K-drama or a performer making their debut. 🔁 RE means a drama previously appeared in the Top 10, dropped out, and has now re-entered the rankings.
What’s New This Week
Four Hands, Two Sonatas entered directly at No. 1 with 20.73% Buzz Share. A Love Other Than Yours also entered at No. 8 before its September 12 premiere, demonstrating how promotional activity can place an upcoming drama in the rankings. The Affair Was Just the Beginning re-entered at No. 10 after falling out last week.
The performer ranking changed sharply, adding five names: Lee Jun-young and Song Kang at Nos. 1 and 2 for Four Hands, Two Sonatas; Lee Hyun-gyun at No. 7 for New Recruit 4: Sabotage; and Ha Seok-jin and Sul Kyung-gu at Nos. 9 and 10. HANI also moved from No. 9 to No. 5.
Three Takeaways From This Week’s Rankings
🎹 Four Hands, Two Sonatas opens with a full-table lead
Four Hands, Two Sonatas did more than debut at No. 1. It also placed Lee Jun-young and Song Kang at Nos. 1 and 2 among performers, giving the premiere week the strongest combined showing across both FUNdex tables.
📈 New Recruit 4 and Mousetrap surge
New Recruit 4: Sabotage rose from No. 8 to No. 2, while Mousetrap moved from No. 7 to No. 3. Together, the two dramas account for 31.71% of the week’s tracked drama buzz. Mousetrap also placed Ryu Jun-yeol at No. 3 and Sul Kyung-gu at No. 10 among performers.
🔄 Last week’s leaders clear the way for a new Top 3
Spooky in Love left the Top 10 after ending its run, while A Bona Fide Killer fell two places and A Shop for Killers Season 2 dropped six. The result is a completely reordered Top 3, led by one debut and two sharply rising dramas.
Reading Between the Numbers
This week’s ranking is unusually concentrated at the top. Four Hands, Two Sonatas, New Recruit 4: Sabotage, and Mousetrap together hold 52.44% of total drama Buzz Share. The gap between No. 3 Mousetrap and No. 4 A Bona Fide Killer is 7.40 percentage points, creating a clear break between the leading group and the rest of the table.
The performer results reinforce that concentration. Five of the Top 10 performers come from the three leading dramas, including both leads from Four Hands, Two Sonatas. My Bias, My Boss and Love on the Menu each placed two performers despite ranking in the lower half of the drama table, showing that cast attention can remain strong even when a title’s overall Buzz Share is smaller.
Global Streaming Snapshot
K-dramas claimed three spots in Netflix’s Global Top 10 Non-English Shows for the week of August 24 to August 30, 2026, and all three ranked in the global Top 5.
Spooky in Love was the highest-ranking K-drama at No. 3 with 2.3 million views and 28.4 million hours watched. Our Sticky Love followed at No. 4 with 2.2 million views and 25.8 million hours watched. Mousetrap debuted at No. 5 with 2.0 million views and 19.2 million hours watched.

The results underline the separation between Korean online buzz and worldwide Netflix viewing. Spooky in Love and Our Sticky Love no longer appear in the FUNdex Top 10, yet both remain among Netflix’s five most-watched non-English shows globally. Mousetrap is the clearest cross-platform performer this week, ranking No. 3 on FUNdex and No. 5 on Netflix.
Beyond Netflix
See You at Work Tomorrow! remained among Prime Video’s most-watched non-English original series worldwide for the week of August 24 to August 30. The South Korean drama ranked No. 7, down two places from the previous week.
For a fourth consecutive week, the drama did not appear in Prime Video’s overall Top 10 Original series ranking, which combines English and non-English titles.

See You at Work Tomorrow! also remains outside the current FUNdex drama Top 10. Its continued presence among Prime Video’s non-English originals shows ongoing international viewing, although its lower position this week indicates softer performance within that chart.
Looking Ahead
The next FUNdex update will show whether Four Hands, Two Sonatas can hold No. 1 after its premiere-week surge and continue placing both leads at the top of the performer table. New Recruit 4: Sabotage and Mousetrap will also face their first test after making large week-over-week gains.
A Love Other Than Yours is worth watching as its September 12 premiere approaches. Its advance entry at No. 8 suggests promotional conversation is already building. On Netflix, Mousetrap will have its first full week of availability, while Spooky in Love and Our Sticky Love will test whether they can extend their global Top 5 runs.
Frequently Asked Questions
What is FUNdex?
FUNdex is a weekly entertainment buzz ranking published by Good Data Corporation in South Korea. It tracks online discussion around television and OTT content, including news coverage, blogs, social media, online communities, and video platforms.
What does Buzz Share mean?
Buzz Share represents a drama or performer’s percentage of the total tracked online conversation for that week. A higher percentage means that title or performer accounted for a larger share of the measured buzz.
Are FUNdex rankings the same as television ratings?
No. FUNdex measures online attention and conversation, not television viewership. A drama can generate strong buzz even if its TV ratings or streaming numbers tell a different story.
Why do Netflix and FUNdex rankings sometimes differ?
The two rankings measure different things. FUNdex reflects online buzz around Korean television and OTT content, while Netflix’s Global Top 10 reflects worldwide streaming activity on Netflix.
How often are the rankings updated?
FUNdex rankings are generally updated weekly. Netflix and Prime Video also publish weekly streaming rankings, while Viki rankings are typically reported monthly through promotional ranking articles.
