If you’ve watched Weak Hero Class 1, you know the feeling. That gut-punch in the final episodes where everything falls apart. It’s hard to talk about the show without mentioning Choi Hyun Wook, the actor who basically carried the "heart" of the series as Ahn Suho.
He wasn't just a fighter. He was the glue.
Honestly, the way people talk about this show in 2026 is still so intense. It’s become a cult classic for a reason. While Park Ji-hoon’s Si-eun was the "Weak Hero," it was Choi Hyun Wook’s Suho who made the stakes feel real. You weren't just watching a kid get bullied; you were watching a genuine, rare friendship get dismantled by pride and insecurity.
Why Choi Hyun Wook in Weak Hero Hit Different
Most K-drama fans already knew Choi from Twenty-Five Twenty-One where he played the "Pretty Boy" of Taeyang High. He was funny. He was charming. But Weak Hero? That was a pivot.
Suho is a complex guy. He’s a former MMA fighter who only goes to school because he promised his grandmother he’d graduate with perfect attendance. He’s sleepy, he’s constantly working part-time jobs, and he has this "I don't care" energy that actually masks a fiercely loyal person.

Choi Hyun Wook didn't just play a tough guy. He played a guy who was comfortable enough in his own skin that he didn't need to prove he was tough. That’s a subtle difference, and it’s why his performance stood out so much. He wasn't posturing. He was just Suho.
The Dynamics of a Broken Trio
The show’s brilliance lies in the relationship between Suho, Si-eun, and Beom-seok (played by Hong Kyung).
- Si-eun is the brain.
- Suho is the brawn (and the social engine).
- Beom-seok is the tragedy.
When Beom-seok starts to spiral due to his own inferiority complex, Suho becomes the target. It’s painful to watch. You’ve got Suho, who genuinely likes Beom-seok, being blindsided by a betrayal he never saw coming. Choi Hyun Wook’s acting in those final scenes—the confusion, the refusal to truly hurt his friend, and the eventual coma—left fans absolutely wrecked.
The 2026 Reality: Is Suho in Weak Hero Class 2?
This is the big question everyone is still asking. Now that Weak Hero Class 2 has landed on Netflix (after moving over from Wavve), the mystery is finally solved.

Here is the factual breakdown: Ahn Suho is effectively out of the main picture for Season 2. If you follow the original webtoon, you know that the story moves to Eunjang High School, following Si-eun's transfer. Suho remains in a coma for a massive chunk of the narrative.
However, Choi Hyun Wook does make a special appearance. It’s more of a cameo to bridge the emotional gap between the seasons. It makes sense. Si-eun’s entire motivation in the new school is fueled by the guilt of what happened to Suho. Without Suho’s presence—even in flashbacks—the "Weak Hero" wouldn't have the same drive.
Choi Hyun Wook’s Career Post-Suho
Since that breakout role, Choi’s career has been on a literal rocket ship. He’s moved far beyond the "high school actor" trope, though he still nails it when he goes back.
- Twinkling Watermelon (2023): He played Ha Yi-chan, proving he could handle heavy emotion and musicality.
- High Cookie (2023): A darker, more psychological thriller role.
- Mantis (2025): His big jump into film as Benjamin Jo.
- Notes from the Last Row (2026): His latest project where he’s taking on much more mature, lead-actor responsibilities.
The "Whynot Award" he won at the Blue Dragon Series Awards for Weak Hero wasn't just a fluke. It was a signal that he was the next big thing.

What Most People Get Wrong About Suho
There’s a common misconception that Suho was just a "good fighter." That’s a surface-level take.
If you look closely at Choi’s performance, Suho is actually quite lonely. He lives with his grandmother, he works exhausting shifts, and he doesn’t really have many friends until Si-eun comes along. His "coolness" is a survival mechanism. He doesn't want trouble because he literally doesn't have the time or energy for it.
When he fights, it's always for someone else. He never fights for himself. That’s the tragedy of the character—his selflessness is exactly what Beom-seok misunderstood as "looking down on him."
How to Experience the "Weak Hero" Impact Today
If you’re late to the party or just want to dive deeper into Choi Hyun Wook’s best work, here is the move:
- Watch the Action: Pay attention to the choreography in Episode 3. Choi did a lot of his own stunts. His background as a baseball player gave him the physical coordination to make the MMA-style fighting look authentic.
- Read the Webtoon: The drama is actually a prequel to the webtoon. If you want to see Suho's legendary status in the "present day" of the story, the manhwa is where it’s at.
- Track his 2026 projects: Check out Notes from the Last Row on Netflix. It shows how much he’s evolved from the raw, scrappy energy of Suho into a polished leading man.
Basically, Choi Hyun Wook in Weak Hero was a lightning-in-a-bottle moment. It changed the way school violence dramas are written because it focused on the loss of friendship rather than just the "win" of a fight.
To get the full picture of his transition into more mature roles, look for his recent work in Mantis or his upcoming series Portraits of Delusion. These projects show a side of him that Suho only hinted at—a range that spans from lighthearted comedy to intense, brooding drama.
