Switch

For years, Choi Baekho endured relentless bullying without fighting back. That changes abruptly when he finally snaps, waking up with bloodied knuckles and fragmented memories to find his tormentors beaten unconscious at his feet. Overnight, his reputation transforms completely. Now feared throughout the halls of Shinheung High as the "crazy dog," Baekho aggressively targets anyone who relies on overwhelming numbers to intimidate others, baring his teeth at every group of bullies foolish enough to cross his path. His violent crusade takes a dangerous turn when he sets his sights on Do Changsoo, the most formidable fighter among the eleventh graders. Attempting to defeat this top-tier rival unexpectedly entangles Baekho with organized crime, dragging him into a conflict far deadlier than any high school brawl. Facing threats from the mob, Baekho is forced into an uneasy alliance with the very person he intended to crush. Together, they must navigate a perilous underworld where survival depends on trust. Ultimately, Baekho must learn to master the volatile mental state that triggers his blackouts—his unpredictable "switch"—if he hopes to control his power and become the ultimate nightmare for those who prey on the weak.
