14 K-Dramas in September 2025 Wrecking My Schedule like a Cannonball..!

My calendar for September is a complete disaster, and I couldn’t be happier about it. It’s not just meetings or deadlines; it’s a chaotic, color-coded grid of premiere dates because the industry has decided to drop an absolute truckload of new K-dramas on us. Seriously, where am I supposed to find the time?

But that’s a problem for future me. Present me has done the hard work of sifting through all the announcements to figure out what’s actually worth the hype. So, if your watchlist is also crying out for help, here’s my personal breakdown of every new show hitting our screens this month.

Let’s dive in.

Week 1: An Explosive Start (Sept 5-6)

The month isn’t easing us in; it’s kicking the door down with three major premieres right away.

My Youth (마이 유스)

• Premiere Date: September 5
• Genre: Romance, Melodrama
• Cast: Song Joong Ki, Chun Woo Hee
• Where to Watch: JTBC, Viki, Viu

Okay, let’s just state the obvious: it’s Song Joong Ki. After blowing us all away in everything from Vincenzo to Reborn Rich, his return is an event. But pairing him with the ridiculously talented Chun Woo Hee (who was just phenomenal in The Atypical Family and the film Han Gong-ju) feels like a stroke of genius. 

The story—about a first love that reappears after 15 years—is classic K-drama fuel, but with these two leading, I’m expecting a masterclass in emotional depth. This is my top pick for a good, soul-wrenching cry.

Queen Mantis (사마귀: 살인자의 외출)

• Premiere Date: September 5
• Genre: Thriller, Crime, Mystery
• Cast: Go Hyun Jung, Jang Dong Yoon
• Where to Watch: Viki, Netflix

I’m a sucker for a dark, twisted thriller, and this one has an incredible pedigree. It’s a remake of the acclaimed French series La Mante, which was genuinely chilling. The Korean version stars the legendary Ko Hyun Jung, who just gave us one of the most unforgettable performances of the decade in Mask Girl. 

Here, she’s a convicted serial killer forced to help her detective son (an interesting role for Daily Dose of Sunshine‘s Jang Dong Yoon) catch a copycat. The sheer psychological mess of that mother-son dynamic? I am so here for it.

Confidence Queen (컨피던스맨 KR)

• Premiere Date: September 6
• Genre: Crime, Comedy
• Cast: Park Min Young, Park Hee Soon, Joo Jong Hyuk
• Where to Watch: TV Chosun, Prime Video, Coupang Play

After the cultural reset that was Marry My Husband, Park Min Young is back, and she’s serving looks and scams. A remake of the Japanese hit The Confidence Man JP, this promises to be pure, stylish fun. She’s a con artist with an IQ of 165 leading a team of swindlers. 

The best part? 

Her crew includes Park Hee Soon (Dr. Brain, My Name) and “Tactician Kwon Min-woo” himself, Joo Jong Hyuk from Extraordinary Attorney Woo. I’m predicting this will be my go-to comfort watch of the month.

Week 2: The Heavy Hitters Arrive (Sept 10-13)

If I thought the first week was big, the second week is when the true titans of the industry show up.

Tempest (북극성)

• Premiere Date: September 10
• Genre: Spy, Action, Romance
• Cast: Jun Ji Hyun, Kang Dong Won, John Cho
• Where to Watch: Disney+

This isn’t just a drama; it’s a cinematic event. We’ve got Jun Ji Hyun, the icon from My Love from the Star, making her grand return. We’ve got Kang Dong Won, a massive film star who rarely does TV. And they’re in a spy thriller from the writer-director team that gave us the masterpiece Little Women. 

This is Disney+’s huge play for the year, and it looks every bit the part. The story of a UN ambassador and a shadowy special agent screams high-stakes and even higher production values. My expectations are sky-high.

You and Everything Else (은중과 상연)

• Premiere Date: September 12
• Genre: Friendship, Slice of life, Melodrama
• Cast: Kim Go Eun, Park Ji Hyun
• Where to Watch: Netflix

Get your tissues ready. Kim Go Eun is one of the best actresses of her generation, period. Here, she’s paired with Park Ji Hyun in a story about the messy, complicated, lifelong bond between two female friends. 

A fun piece of trivia: these two actually shared the screen in Yumi’s Cells, though their characters were far from friends. Seeing them lead a drama focused entirely on their dynamic—one that spans from admiration to resentment until one asks the other to see her through her final days—is going to be absolutely gut-wrenching and beautiful.

A Hundred Memories (백번의 추억)

• Premiere Date: September 13
• Genre: Youth, Period, Romance
• Cast: Kim Da Mi, Shin Ye Eun, Heo Nam Jun
• Where to Watch: JTBC, Viki

I’m immediately drawn to anything starring Kim Da Mi, whose raw energy in Itaewon Class and quiet charm in Our Beloved Summer made her a favorite. Here, she’s starring alongside Shin Ye Eun (who gave us chills in The Glory) in a nostalgic trip to the 1980s. 

They play two bus attendants and friends whose lives are upended by their shared first love. It feels like a recipe for a beautiful, bittersweet coming-of-age story.

Week 3: Quirky, Gritty, and Grounded (Sept 15-20)

Mid-month brings a fascinating mix of genres that stand out from the crowd.

Shin’s Project (신사장 프로젝트)

• Premiere Date: September 15
• Genre: Black Comedy
• Cast: Han Suk Kyu, Bae Hyeon Seong, Lee Re
• Where to Watch: tvN, Viu

You can’t go wrong with Han Suk Kyu. The man is a living legend, best known as the heart of the Dr. Romantic series. The premise here is just delightful: he plays a former top-tier negotiator who now runs a chicken joint and can’t help but mediate all the local disputes. It sounds like a quirky, character-driven show that will be equal parts funny and heartwarming. I’m always looking for a hidden gem, and this could be it.

To The Moon (달까지 가자)

• Premiere Date: September 19
• Genre: Office, Comedy
• Cast: Lee Sun Bin, Ra Mi Ran, Jo Aram
• Where to Watch: MBC (Streaming TBA)

A comedy about three office workers diving into crypto? It feels so ridiculously current. But the real draw is the cast. The incomparable Ra Mi Ran (The Good Bad Mother) can make any script hilarious, and Lee Sun Bin (Work Later, Drink Now) has impeccable comedic timing. I’m expecting a chaotic, relatable, and genuinely funny story about friendship and trying to get rich quick.

Walking On Thin Ice (은수 좋은 날)

• Premiere Date: September 20
• Genre: Crime, Thriller
• Cast: Lee Young Ae, Kim Young Kwang
• Where to Watch: KBS2, Viki

The one and only Lee Young Ae—an icon known for the historical epic Dae Jang Geum—is starring in a dark crime thriller. That sentence alone is enough. She plays a housewife who becomes a drug seller to protect her family, partnering with a teacher (Kim Young Kwang) who is secretly a drug dealer. Watching this elegant, legendary actress dive into such a gritty, desperate role is an opportunity I absolutely will not miss.

Week 4: An Unbelievably Packed Finish (Sept 22-29)

Just when I thought I could catch my breath, the last week of September drops five more dramas. FIVE.

• A Graceful Liar/친밀한 리플리 (Sept 22, KBS2): A daily drama with a wild premise—a woman’s long-lost birth mother becomes her stepmother-in-law. Expect makjang-level twists.
• No Mercy/단죄 (Sept 24, Dramax): I love a good revenge plot. Lee Joo Young (Itaewon Class) uses deepfake tech to take down a phishing ring that destroyed her family. Sounds intense and very modern.
• First Lady/퍼스트레이디 (Sept 24, MBN, Viki): Eugene from The Penthouse is back in the world of high-society drama. Her husband asks for a divorce right before his presidential inauguration. The potential for scandal and backstabbing here is off the charts.
• The Murky Stream/탁류 (Sept 26, Disney+): A historical action drama starring Rowoon, who seems to be showing a much darker side, and Shin Ye Eun in her second drama of the month. It’s a Disney+ production, so I’m expecting it to look incredible.
• Ms. Incognito/착한 여자 부세미 (Sept 29, ENA, Viki): Jeon Yeo Been (Vincenzo) in a contract marriage with a terminally ill chaebol chairman? It’s a classic setup, but with an actress as compelling as her, I’m sure it will be anything but predictable.

Okay, I’m exhausted just writing all that out. September is going to be an incredible, sleep-deprived month for us K-drama fans. My own priority list is probably Tempest, My Youth, and Walking On Thin Ice, but honestly, I’ll probably try to watch them all.

Now I have to know—what are you most excited to watch? And which drama do you think I’m totally underrating? Let me know!
