ONE: High School Heroes (Season 1)

ONE: High School Heroes (2025) is a Korean action-drama series directed by Lee Seong-tae that you can watch online on iFILM. The premise starts with a familiar type: a model student with perfect grades and a home life no one sees — domestic violence behind closed doors, bullying at school, and adults who choose not to notice.

Instead of enduring it alone, he links up with a small group of classmates and they form something unofficial: a crew that steps in where teachers and administrators won't, protecting students who are being pushed around. Kim Sang-ho, Kim Joo-ryeon and Shin Chun-seop lead the ensemble through a series that mixes action sequences with sharper questions about why school hierarchies go unchecked.

Korean dramas about the social dynamics of adolescence tend to land harder than Western equivalents — this one follows that pattern. Stream ONE: High School Heroes (2025) online on iFILM.
