New K-Dramas Landing On Netflix This September Are Worth Clearing Your Calendar For

September is shaping up to be one of the strongest K-drama months on Netflix all year. From a scandalous historical remake to Song Kang’s long-awaited comeback, here’s everything worth knowing before it drops.

Quick Overview

September brings a very exciting slate of new K-dramas on Netflix, including the debut of “The Scandal,” a steamy adaptation of the beloved 2003 Korean film, Yeom Jung Ah and Hwang Jung Min’s return for the “Mission: Cross” sequel, and Song Kang’s grand comeback in “Four Hands, Two Sonatas.”

The Scandal — A Steamy Joseon-Era Remake

Set toward the end of the Joseon Dynasty, “The Scandal” follows Madam Jo, a devoted wife who secretly resents society’s restrictions and has quietly carried on discreet relationships with other men. Jo Won is an accomplished scholar and skilled martial artist whose real passion is seducing women, and Madam Jo — his first love — has engaged in high-stakes games of seduction and love with him ever since, with both hiding their true feelings while she sets him upon the innocent So Ok, who becomes her husband’s concubine.

Netflix hasn’t officially confirmed the September release, but based on the platform’s usual K-drama schedule, an 8-episode debut on September 18, 2026 is all but certain, with Son Ye Jin, Ji Chang Wook, Nana, Chani, and Han Sun Hwa leading the cast.

Mission: Cross 2 — Espionage Meets Marriage Comedy

There’s no confirmed release date yet, but with the film slated for a Q3 release and no August 2026 date announced, a September premiere looks likely, directed by Lee Myung Hoon with Hwang Jung Min, Yeom Jung Ah, Jeong Man Sik, Lee Ho Chul, and Yoon Kyung Ho starring.

Four Hands, Two Sonatas — Song Kang’s Big Return

Piano prodigy Kang Bi O’s steady rise to the top is threatened by the sudden arrival of Choi Jeong Yo, a gifted rival who had previously abandoned his talent. Joined by Hong Jae In, a viola major with exceptionally sensitive hearing and Bi O’s devoted friend, the three navigate the high-pressure world of classical music, forging deep connections while confronting their pasts and ambitions.

The 12-episode series airs new episodes on Saturdays and Sundays, wrapping up with its finale on October 4, 2026, and features Song Kang, Lee Jun Young, Jang Gyu Ri, Kim Joo Heon, and Yoon Se Ah. This marks a major comeback for Song Kang, an actor whose career has been closely tied to the platform’s biggest Korean hits.

Why This Lineup Matters

September’s slate spans three very different corners of storytelling — forbidden romance, spy-thriller comedy, and coming-of-age music drama — reflecting just how diverse Korean dramas have become on the global stage. With period intrigue, marital espionage, and classical music rivalry all landing in the same month, there’s genuinely something for every kind of viewer.
