Oh Beom-seok is a more straightforward antagonist with less focus on his internal conflict.
To help explore this series further, let me know if you want to look into:
The story follows (played by Park Ji-hoon), a top-tier student who is physically frail and entirely indifferent to social hierarchies. Unlike other underdog protagonists, Si-eun doesn't undergo a training montage to gain muscle. Instead, he weaponizes his environment—using physics, school supplies, and psychological tactics to dismantle his bullies.
When his academic excellence draws the ire of privileged bully Jeon Young-bin (Kim Su-gyeom), Si-eun becomes the target of a vicious, drug-fueled hazing plot. Rather than backing down, Si-eun uses his knowledge of physics, psychology, and his immediate environment to retaliate with terrifying precision.

Bum-seok is the catalyst for the show’s tragic trajectory. As the adopted son of a powerful politician, he transfers to the school after suffering severe abuse at his previous institution. He is deeply insecure, desperate for validation, and profoundly broken. While Shi-eun and Soo-ho accept him, Bum-seok’s internal trauma leaves him vulnerable to manipulation.
Beom-seok is the most tragic figure. Initially, he seems like just another weak kid trying to survive by latching onto powerful people. But Beom-seok harbors deep, ugly insecurities. He wants to be strong, but he lacks the brain of Si-eun and the brawn of Su-ho. Hong Kyung plays this desperate need for validation with such painful accuracy that you will simultaneously pity and loathe him. He is the wildcard who drives the plot toward its devastating finale.

The series excels in its gritty, realistic portrayal of school violence. It moves away from the stylized "glamour" of typical action dramas, opting instead for a raw and often painful depiction of the consequences of bullying. The choreography is grounded; every hit feels heavy, and every confrontation carries genuine stakes. Beyond the violence, the heart of the show lies in the volatile chemistry between its three leads. Their brotherhood provides a brief respite from the harsh environment of their school, making the eventual tragic turns in their relationship even more impactful.
The brilliance of Shi-eun’s character lies in his psychological state. His violence is not born out of a desire for dominance, but from a desperate need to protect his fragile sanctuary of quiet isolation. Park Ji-hoon’s performance relies heavily on micro-expressions. His dead, unblinking eyes convey a terrifying void, revealing a teenager who has normalized emotional neglect long before facing physical threats.
Directed by Yoo Su-min and creatively supervised by Han Jun-hee (director of D.P. ), the series boasts exceptional production value.

Weak Hero Class 1 stands as a benchmark for contemporary television. It proves that the school action genre can be profoundly intellectual, emotionally devastating, and socially resonant. By treating its teenage characters with absolute psychological seriousness, the series lingers in the mind long after the final bell rings.
Upon its release, Weak Hero Class 1 became an instant critical and commercial phenomenon, dominated streaming charts, and earned prestigious nods at the Baeksang Arts Awards and the Blue Dragon Series Awards. It successfully proved that webtoon adaptations can surpass their source material by deepening character psychology and grounding stylized fiction in raw human emotion.

While some praised the acting and action, many fans of the webtoon criticized Season 2 for rushing through hundreds of chapters of source material and condensing beloved character arcs. However, for those who haven't read the webtoon, it remains an entertaining and action-packed follow-up to a stellar first season.
