The WONDERfools

The WONDERfools (2026) K-Drama: Cast, Story, Episodes, Release Date & Where to Watch

The WONDERfools (2026) is a South Korean superhero comedy drama that combines action, fantasy, science fiction, and adventure with a nostalgic story set in 1999, a time when fears about the end of the world and the Y2K problem were spreading around the globe. The Netflix series follows a group of ordinary and somewhat clumsy people who unexpectedly gain supernatural powers and are forced to work together to protect their hometown from dangerous villains.

Starring Park Eun-bin, Cha Eun-woo, Choi Dae-hoon, Im Seong-jae, Kim Hae-sook, and Son Hyun-joo, The WONDERfools offers a different take on the superhero genre by focusing on imperfect people who have absolutely no idea how to control their new abilities.

The series premiered on Netflix on May 15, 2026, and consists of 8 episodes.

The story takes place in 1999, when many people are convinced that the end of the world is approaching. In the middle of this atmosphere of fear and uncertainty, a group of unusual residents in Haeseong City suddenly obtain supernatural powers after becoming involved in an unexpected incident.

The people who gain these powers aren't trained superheroes. They are ordinary residents with plenty of personal problems, awkward personalities, and very little experience dealing with extraordinary situations.

At the center of the story is Eun Chae-ni, a lively and unpredictable woman who lives with her grandmother. Chae-ni becomes involved in a mysterious incident and suddenly develops a supernatural ability.

Her neighbors Son Gyeong-hun and Kang Ro-bin are also affected by the same incident and develop powers of their own. Unfortunately, their abilities aren't exactly easy to control.

The three eventually become involved with Lee Un-jeong, a strict and socially awkward civil servant who has arrived in Haeseong City from Seoul.

Together, this unlikely group discovers that strange people are disappearing from the city and that something much bigger is happening behind the scenes.

The WONDERfools Story

Eun Chae-ni is known around Haeseong City as someone who often causes trouble. She is energetic, impulsive, and doesn't always think before acting.

Her life takes a dramatic turn when an unexpected incident gives her supernatural powers.

Chae-ni isn't the only one affected. Her neighbors Son Gyeong-hun and Kang Ro-bin also develop unusual abilities, but neither of them knows how to properly use them.

Meanwhile, Lee Un-jeong arrives in Haeseong City from Seoul to work as a civil servant. Unlike Chae-ni and her friends, Un-jeong is extremely serious about following rules and principles. He is also uncomfortable around other people and isn't exactly the easiest person to work with.

As mysterious disappearances begin occurring throughout Haeseong City, Un-jeong becomes involved in the investigation. His investigation eventually brings him together with Chae-ni and the other newly powered residents.

What starts as a group of confused people trying to understand their abilities gradually turns into a fight against a dangerous organization and villains threatening the peace of Haeseong City.

Park Eun-bin as Eun Chae-ni

Park Eun-bin plays Eun Chae-ni, the central character of The WONDERfools.

Chae-ni is energetic, unpredictable, and known as one of Haeseong City's biggest troublemakers. She lives with her grandmother, Kim Jeon-bok, who is her only remaining family.

After the mysterious incident, Chae-ni gains a supernatural power that completely changes her life.

Rather than becoming a perfect superhero overnight, she has to figure out how her ability works while dealing with the chaos it creates around her.

Her personality also makes her one of the funniest characters in the series. She isn't afraid to say what she thinks, and her impulsive behavior frequently puts the entire group into unexpected situations.

Cha Eun-woo as Lee Un-jeong

Cha Eun-woo stars as Lee Un-jeong, a civil servant who arrives in Haeseong City from Seoul.

Un-jeong is very different from Chae-ni. He is serious, follows rules closely, and has strong personal principles. However, he has difficulty communicating with other people and often comes across as socially awkward.

Despite his reserved personality, Un-jeong becomes an important part of the group's investigation into the mysterious disappearances happening around Haeseong City.

He also possesses a supernatural ability, making him an important member of the team.

The WONDERfools Superpowers

The 1999 Setting

One of the biggest attractions of The WONDERfools is its nostalgic 1999 setting.

The drama takes place just before the new millennium, when fears about Y2K and the supposed end of the world were widespread.

Instead of using a modern setting filled with smartphones, social media, and advanced technology, the series embraces the culture and atmosphere of the late 1990s.

This gives the drama a distinctive visual style while also creating plenty of opportunities for comedy.

The combination of Y2K panic, small-town life, supernatural powers, and superhero action makes The WONDERfools very different from a typical modern Korean drama.

Who Directed The WONDERfools?

The series was directed by Yoo In-sik, the director behind popular Korean dramas including Extraordinary Attorney Woo and Dr. Romantic.

The connection with Extraordinary Attorney Woo is particularly notable because The WONDERfools reunites Yoo In-sik with Park Eun-bin.

The screenplay was written by Huh Da-joong, who is known for his work on the comedy film Extreme Job.

Kang Eun-kyung, known for projects including Dr. Romantic and Gyeongseong Creature, serves as the creator.

This combination of experienced comedy and drama creators helped give The WONDERfools its unusual mix of superhero action, emotional character moments, and comedy.

What Makes The WONDERfools Different?

The biggest difference between The WONDERfools and many superhero stories is its characters.

These aren't highly trained heroes who have spent years preparing for battle.

They are ordinary people who suddenly receive extraordinary abilities.

They make mistakes. They misunderstand their powers. They argue with each other. They panic when things go wrong.

That makes the series much more comedic than a traditional superhero drama.

At the same time, the characters gradually develop into a genuine team as they realize that their powers can be used to protect the people around them.

Is The WONDERfools Worth Watching?

If you enjoy Korean dramas that combine comedy, action, fantasy, superheroes, mystery, and adventure, The WONDERfools is definitely worth checking out.

The series is especially appealing to viewers who enjoy stories about ordinary people suddenly being placed in extraordinary situations.

Park Eun-bin and Cha Eun-woo provide the main star power, while the supporting cast adds plenty of humor and personality.

The 1999 setting also gives the series an unusual nostalgic atmosphere that separates it from many other 2026 K-dramas.

Where to Watch The WONDERfools

The WONDERfools is a Netflix Original Korean series and premiered globally on May 15, 2026.

The complete 8-episode series is available to stream on Netflix.
