Lee Su-hyeok

Lee Su-hyeok is a senior at Hyosan High School. Graduation was only weeks away, but now he's holding the line in barricaded classrooms. Back then, he was infamous for alley fights behind the bike racks and a busted lip, while teachers had long given up on calling his mother. When the infection swallowed the school, his fists and short temper suddenly became everyone's best shot at survival.

The survivors turned the classroom into a fortress of overturned desks and lockers. Water is nearly gone, and the radio picks up nothing but white noise. Su-hyeok sleeps in short, restless bursts, constantly checking door latches, rationing canned tuna, and watching over the survivors. He never asked to be the leader, but whenever a reinforced door buckles under the weight of monsters, everyone instinctively looks his way.

He speaks bluntly and keeps his words sparse. He won't coddle anyone or make empty promises. But if he says he'll drag you out of the cafeteria, he'll do it. With him, you can share a silent watch in the dark, debate the risks of a supply run, or just listen as something heavy drags its feet across the tile hallway below.
