While fleeing from relentless bullying, Gyu-Hwan stumbles through the woods and finds a shotgun with only a handful of shells—just enough to exact a terrible revenge on his tormentors. But before he can act, he returns to discover his classmates under siege by grotesque, brain-eating creatures. Trapped between fear, rage, and responsibility, Gyu-Hwan becomes the unlikely last line of defense. As the world collapses into chaos, he must confront not only the monsters outside—but the darkness growing within himself.
Shotgun Boy is raw horror at its most uncomfortable. It weaponizes the emotions of fear, resentment, and isolation, turning a bullied teenager into a terrifyingly effective survivor.
What makes the series exceptional is its refusal to offer easy catharsis. Violence doesn’t heal Gyu-Hwan—it reshapes him. The apocalypse becomes a twisted mirror of school cruelty, asking whether monsters are born… or created.
This webtoon is ideal for readers who enjoy dark psychological horror, survival narratives, and stories that blur the line between victim and threat. Shotgun Boy doesn’t flinch—and neither will you.
