At Hyosan High, everyone knew who Yoon Gwi-nam was. A bully. A problem. A threat that walked the halls with a grin too sharp to trust. Students avoided him. Teachers pretended not to see him. Fear followed him like a shadow. But then there was you. You sat in the same class as Lee Su-hyeok, Nam On-jo, and Choi Nam-ra, moving easily between them like you belonged exactly where you stood. You laughed with On-jo, shared quiet moments with Nam-ra, and tolerated Su-hyeok’s constant hovering like a patient younger sister used to being watched. Because Su-hyeok was protective. Everyone knew that too. What no one noticed at first—what no one expected—was the way Gwi-nam never touched you. He mocked others. He shoved desks. He cornered students without remorse. But when his eyes landed on you, something shifted. His voice didn’t rise. His steps slowed. His usual cruelty dulled into something quieter… darker. Interest. You didn’t flinch when he passed. You didn’t challenge him either. You treated him like he didn’t matter—and that was worse than fear. Gwi-nam hated that. He watched you more than he should have. From the back of the room. From the stairwell. From across the courtyard. You were always with people—always protected—but never unreachable. And yet, you kept your distance, playing hard to get without ever meaning to. It became an obsession he never spoke out loud. Su-hyeok noticed. Every time Gwi-nam lingered too close, Su-hyeok moved closer to you. Every time Gwi-nam’s gaze followed you, Su-hyeok stepped in front of it. The tension between them crackled—silent, dangerous. Nam-ra sensed it too. Her eyes followed Gwi-nam when she thought no one noticed. On-jo stayed closer to you without knowing why. Then the outbreak happened. Chaos swallowed the school. Screams replaced bells. Blood stained the floors. And in the middle of it all, something terrifying became clear— Gwi-nam was still watching you. Even as the world collapsed, he remembered exactly where you were. He didn’t chase others the same way. He didn’t corner you like the rest. You were different. And when Su-hyeok stood between you and him, fury lit Gwi-nam’s eyes—not just hatred, but something twisted and possessive. You weren’t just another student. You were the one thing at Hyosan High that Gwi-nam refused to destroy. And in a school overrun by monsters, that might have been the most dangerous thing of all.
