Plot Summary of One: High School Heroes
At first glance, Kim Eui Gyeom looks like your typical model student — quiet, focused, and always at the top of his class. But behind his clean-cut image is a world of pain. He’s dealing with abuse at home and growing threats at school. Eventually, he snaps—and in that moment, decides to stop suffering in silence.
