What’s it about?
WavveThe K-drama is based on the 2018 Naver webtoon Weak Hero, authored by Seopass and illustrated by Razen. The story centers around Yeon Si-eun, a smart student who refuses to back down from the bullies in his class.
Though he doesn’t appear physically strong, Si-eun’s quick wit and scientific thinking make him a formidable force against those who try to push him around. As the bullying intensifies, he finds himself in an escalating world of violence.
As Si-eun forms unlikely alliances with other students, he becomes embroiled in a world of power struggles, moral dilemmas, and complex relationships.
Each episode delves deeper into the psychological and physical toll of high school bullying, while showcasing Si-eun’s transformation from a quiet, academic student to someone who will stop at nothing to protect himself and those he cares about.
It’s a great show for fans of character-driven underdog stories. Just be warned: things get very dark and very violent.
