About Weak Hero

Yeon Si-eun is a quiet but brilliant high school student who copes with relentless bullying by using brains and carefully measured violence. When a few unexpected classmates start to stand by him, he begins to push back against the gangs that run his school, setting off a chain of escalating clashes that pull him deeper into danger. The show follows his tactical choices, shifting alliances, and the cost of standing up in a place where strength is currency. It keeps the focus on character and consequence, avoiding neat answers as the situation grows more serious and complicated.

Released in 2022, the series was directed by Park Dan-hee and created by You Su-min, Han Jun-hee, and 류현, adapted from a popular webtoon source material. The production highlighted tight choreography and a grounded visual style to match the story's tense schoolyard confrontations.

Critics and viewers rated the show highly, reflected in an 8.6/10 average from audience votes. Reviews praised the lead performances and the way episodes balance tense action with quieter character moments. Major themes include power dynamics among teens, the ethics of retaliation, and how friendship can reshape someone's choices, all treated with a gritty, realistic tone.

The series built a noticeable online following, with fans sharing reactions, scene breakdowns, and fan art. It helped raise the profile of several young cast members and sparked conversations on social media about school violence and methods of resistance. That online energy kept discussion going between seasons and contributed to the show’s visibility beyond its home market.

There are no widely reported major awards listed in the provided information, so specifics about nominations or wins aren't available here. Nonetheless, the program's positive audience ratings and the attention it drew from critics suggest it achieved solid recognition among contemporary Korean drama offerings.
