Netflix's September 2026 K-Drama Slate Is Absurdly Stacked: The Scandal, Mission: Cross 2, and Song Kang's Big Return

September 2026 Is Looking Like the Strongest K-Drama Month on Netflix All Year

Okay, August is still happening, but can we talk about September for a second? Netflix just quietly lined up one of its most loaded K-drama schedules of 2026 — a scandalous Joseon-era remake, a spy-comedy sequel, and the comeback of one of K-drama's biggest stars. If you've been waiting for a reason to clear your calendar, this is it.

1. The Scandal — Son Ye Jin and Ji Chang Wook Finally Team Up

First up is The Scandal, a steamy adaptation of the beloved 2003 Korean film Untold Scandal. Set near the end of the Joseon Dynasty, it follows Madam Jo — a devoted wife who secretly carries on relationships with other men — and Jo Won, a scholar and martial artist whose real passion is seduction. Their high-stakes game of love and deception pulls in the innocent So Ok, and things get properly messy.

The cast alone is going to break the internet: Son Ye Jin (Crash Landing on You) as Madam Jo, Ji Chang Wook (Lovestruck in the City) as Jo Won, plus Nana, Chani, and Han Sun Hwa. Netflix hasn't made it official yet, but an 8-episode premiere on September 18, 2026 is looking all but certain. Yes, we're already marking the calendar.

2. Mission: Cross 2 — The Chaotic Spy Couple Is Back

If romance isn't your thing, Mission: Cross 2 has you covered. Hwang Jung Min returns as Gang Mu, a former special ops agent dragged back into action when the President needs a stolen national treasure recovered — and he's bringing his wife (and former shooting champion turned detective) Mi Seon along, played by Yeom Jung Ah. Expect the same blend of espionage chaos and married-couple bickering that made the first film a hit, with director Lee Myung Hoon back behind the camera alongside Jeong Man Sik, Lee Ho Chul, and Yoon Kyung Ho. A September premiere is expected after no August date materialized.

3. Four Hands, Two Sonatas — Song Kang's Grand Comeback

And then there's the one everyone's been waiting for: Song Kang's big return. After his military service, the Sweet Home and My Demon star is leading Four Hands, Two Sonatas, a 12-episode music romance about piano prodigy Kang Bi O, whose rise is threatened by a gifted rival — played by Lee Jun Young — and the viola player with superhuman hearing caught between them, played by Jang Gyu Ri.

The show premieres on tvN and drops new episodes every Saturday and Sunday, wrapping up with its finale on October 4, 2026. Supporting cast includes Kim Joo Heon and Yoon Se Ah. Given Song Kang's track record on Netflix, expect this one to dominate the platform's global charts from week one.

Bottom Line: September Is a No-Skip Month

Forbidden historical romance, spy-thriller comedy, and a coming-of-age music drama — all landing within weeks of each other. Whether you're here for Son Ye Jin's return to sageuk, Hwang Jung Min's action comedy, or Song Kang's long-awaited comeback, September 2026 has something for every kind of K-drama fan. Clear your queue, set your reminders, and get ready.
