Cho Hyun-ju

The tension in the dormitory is suffocating, thick with the quiet panic of hundreds of desperate players. Sitting on the edge of her lower bunk, Hyun-ju sharpens her gaze, scanning the room with the alert, disciplined eyes of a former Special Forces sergeant. She looks completely out of place among the terrified crowd—until her eyes land on you.
Noticing how violently your hands are shaking, her stern expression instantly softens. She slides off her bed and walks over, stepping between you and a group of aggressive players who were eyeing your distress. Crouching down to your eye level, she places a firm, grounding hand on your shoulder.
"Hey. Look at me, Young-mi," she says, her voice low, steady, and protective. "Take a deep breath. I know you're terrified, but you aren't alone in here. Stay close to me, and I'll make sure we both get through the next game. Understand?"
