5 K-dramas to catch in Sep: Tempest, My Youth, Mantis and more…

As the sweltering heat of summer fades, South Korea transforms into a picturesque landscape of crimson maples and golden trees. With that, September brings a fresh lineup of K-dramas that are just as captivating as the changing leaves.

To help you decide what to watch and catch, HallyuSG has narrowed down five of our must-watch series below.

1. My Youth

Song Joong-ki makes his return to the world of romance dramas with a new slice-of-life melodrama, My Youth (2025).

Though the trailer makes it look like yet another fluffy romance drama, some netizens are wary of the potential heartbreak and emotional turmoil the show may bring. 

My Youth tells the story of Sunwoo Hae (Song Joong-ki). Hae is a novelist and florist whose inner light was extinguished by the greed of the entertainment industry, which exploited him during his years as a popular child actor.

The peaceful lifestyle he built for himself is then suddenly disrupted by the appearance of Seong Je-won (Chun Woo-hee), his first love.

My Youth premieres on Viu on 5 Sep.

2. Queen Mantis

In this gripping mystery thriller based on the 2017 French series La Mante, former serial killer Jung Yi-shin (Ko Hyun-jung) is unexpectedly approached by her estranged son.

Her son is a police officer who’s asking for help to solve a chilling new case. The catch? The murderer appears to be imitating her signature style.

Queen Mantis premieres on Netflix on 5 Sep.

3. Tempest

Tempest features one of the most impressive international line-ups in a Korean drama to date.

It does not just feature a star-studded cast. It’s also directed by Kim Hee-won, behind works like Queen of Tears (2024) and Vincenzo (2021).

This riveting thriller follows Seo Mun-ju (Gianna Jun), a skilled former diplomat, as she tries to uncover the truth behind an attempt on a presidential candidate’s life.

Her digging unlocks a Pandora’s box of deception, state secrets and more that puts her life in danger, leading her to enlist the help of Paik San-ho (Gang Dong-won), a mercenary, to keep her safe.

Tempest premieres on Disney+ on 10 Sep.

4. You and Everything Else

Be sure to have your tissues ready for this one. In this emotional slice-of-life drama, the only antagonist is, once again, just life itself.

You and Everything Else (2025) shows us just how quickly admiration can turn into jealousy and resentment in a friendship; something most of us can relate to.

Despite having multiple fallouts and reconciliations throughout their teenage years to adulthood, this time might be the last for Ryu Eun-joong (Kim Go-eun) and Cheon Sang-yeon (Park Ji-hyun). As one of them doesn’t have much time left. 

You and Everything Else premieres on Netflix on 12 Sep.

5. Shin’s Project

This comedic drama starring veteran actor Han Seok-kyu follows the story of Mr. Shin (Han Seok-kyu). He is a fried chicken store owner by day who hides a mysterious past beneath the surface.

His talent for charming others is especially evident in his alter ego, where he takes on the role of someone who helps resolve conflicts for those facing impossible odds and little hope of success.

Shin’s Project premieres on Viu on 15 Sep.
