As the new year begins, K-drama enthusiasts are all set for the lineup of new series, which also includes The WONDERfools featuring some of the most globally adored stars from the Korean entertainment industry. And what's currently drawing attention is the new poster.
Yes, that's correct! Netflix has finally updated the first poster for Cha Eun-woo's The WONDERfools on the streaming platform. It includes all main cast members: Park Eun-bin, Choi Dae-hoon, Im Sung-jae, and the True Beauty star.
The K-drama was confirmed last year when Netflix shared a group photo of the key cast members and pictures of script reading. The big deal about this upcoming series is that it will be Cha Eun-woo’s first time leading a Netflix original series.
The K-pop idol is currently serving in the military but remains active in interacting with fans online. Filming for the K-drama began in late October 2024 and wrapped up in late May 2025, and is now set for a release in 2026.
Netflix revealed the first poster for Cha Eun-woo's K-drama The WONDERfools

If you've been waiting for the first glimpse of the upcoming sci-fi and comedy K-drama, The WONDERfools, then tune in to Netflix right now. The newly updated poster immediately sets a playful and chaotic tone rather than a serious superhero atmosphere.
The image captures four characters tightly packed together beside what appears to be a small vehicle, all frozen in a moment of shock. Their wide eyes, open mouths, and stiff body language suggest that something unusual or unexpected has happened in front of them.
At the center of the group is Cha Eun-woo's character, Lee Woonjung (also known as Lee Un Jeong) dressed in formal. Woonjung has been working as a government employee and is very strict when it comes to following rules about his job.
And when it comes to social gatherings, he's quite awkward. And then his neat glasses in the poster of The WONDERfools also explain that Woonjung is the "out of place" person in that scene.
Not to forget that the poster also has Park Eun-bin, the beloved actress who made headlines through her role in Extraordinary Attorney Woo on Netflix. She's playing the role of Eun Chae-ni, whose exaggerated expression on the poster suggests a lively yet chaotic personality, as indicated by her mismatched clothing style.
The poster also features Choi Dae-hoon's Song Gyeog-un and Im Sung-jae's Kang Ro-bin, both physically entangled with the other two, as if they're all a team. None of them looks heroic or confident. Instead, they seem overwhelmed and unprepared, which is going to make this superhero K-drama unique and engaging.
A release date for The WONDERfools hasn't been revealed yet, but the series will come out in 2026.

What is The WONDERfools K-drama about? Plot details explained

The WONDERfools blends multiple genres rather than sticking to one style. It mixes superpowers, comedy, action, and adventure to create a story that feels entertaining and unconventional at the same time. And to give a nostalgic feel, Netflix has set the story in 1999.
Yes, that's right. The events will take place in 1999, which isn't just a normal year. It was a period when many belived that the world was about to end, making people anxious and leading to a chaotic atmosphere.
The main focus is on a group of individuals from Haeseong City. Their lives take the most unexpected turn when these people suddenly get superhuman abilities. And to make it more complicated, they don't know how to use or control them.
But despite the challenges and chaos, the team comes together and fights dangerous forces. This way, The WONDERfools is going to be a K-drama that has sci-fi, comedy and action all together.
