The First Formation
The shadows of the people lined up along the corridor felt awkward. At the front stood Haneul gripping her sword, with Chaewon right behind her. In the middle, students huddled around the wounded, while Euna guarded the rear with an iron dumbbell in hand. Juha and Eunjae moved back and forth along the line, tending to everyone. It was still clumsy, and their rhythm was far from perfect, yet a formation had taken shape.
Haneul advanced slowly at the head of the column. Her blade had already drunk blood more than once. There had been no chance to wipe it clean between the endless movement and fighting, so the edge that should have gleamed now carried dark, stubborn stains. Even so, the weight and balance in her grip felt unchanged.
She scanned the surroundings without pause as they walked. The positions of corpses. Blind corners. Doors open or shut. The scrape of distant movement. How far the blood had spread across the floor. Whether her next step would slip. The school had lost its old shape and become enemy territory. Zombies could burst from anywhere, and a single moment of hesitation could mean the person behind her would be bitten. This was nothing like moving alone. Until now she had only needed to judge quickly and clear the dangerous spots, but now dozens of lives trailed in her wake. She could not push the pace too hard, could not let any fight drag on, and above all could not create unnecessary battles. Leading others felt different from trusting only her own sword. The unfamiliar sensation settled strangely inside her.
Haneul kept her eyes forward yet remained aware of the people at her back. If she stopped, the entire line stopped with her. If she chased a single zombie too deep, the formation’s flank would be left exposed. She had to control not only her strikes but the very speed of their advance. It was the first time she had done so, and it was not as unpleasant as she had expected.
The column passed the special-activities building and headed toward the gym. Not every path opened smoothly, however. As they neared a corridor intersection, Haneul naturally slowed her steps. The crossroads were open on all sides and connected to other hallways, making them easy places for zombies to gather. In daylight the space would have felt bright and airy; now that same openness felt like a threat.
She could see them from a distance—at least six, possibly seven. Some leaned against the walls, others crouched over corpses, and one raised its head after hearing movement from around the corner. The number itself was manageable. Haneul could cut them down alone. The problem was the noise and the time it would cost. A direct fight here risked drawing more zombies from the surrounding corridors.
Chaewon understood at once why Haneul had halted. She too surveyed the scene. They could win if they fought, but winning and choosing to fight were not the same. Stirring up a commotion at the intersection would endanger the students behind them. One bite or one panic and the line would collapse.
Then Euna slipped forward from the rear. In her hand was the whistle she had taken from the gym storeroom. It was an ordinary coach’s whistle, yet in this school it could carry as much weight as a gunshot. She glanced toward the far side of the intersection, then looked at Haneul and Chaewon. No long explanation was needed. One sharp blast to draw their attention, and the rest of the group would slip through. Simple, but the most practical option they had.
Euna moved away from the line and positioned herself farther down the opposite corridor. Her steps were quick but controlled. She found her spot before the zombies at the crossroads noticed her, then blew the whistle in one short, piercing note.
Beep—
The thin, shrill sound echoed through the hallway. Every zombie at the intersection turned toward it. Their clouded eyes fixed on the source, and one by one they began to shamble after the noise. The moment they moved, Haneul acted.
“Now.”
She stepped forward. Two zombies still lingered near the crossing, but it was enough. The first lost its head before it could fully turn; the second staggered when Chaewon’s staff cracked its jaw, and Haneul’s blade finished it. From behind, Eunjae urged the students onward.
“Don’t stop. Not for anything.”
Juha supported an injured student by the waist and pushed the pace. The line slid through the intersection like water. When one student nearly slipped on the blood, Chaewon caught her. Haneul waited until everyone had passed, then struck the remaining zombies from behind. The last one fell when Euna smashed its face with the iron dumbbell.
The whole exchange lasted only seconds, yet something new had been born in that brief span. Until now Haneul had always solved problems with her sword, cutting straight through. At the intersection they had paused, used sound to lure the enemy away, and kept the formation intact while crossing. For the first time the group had opened a path without fighting.
Once past the crossroads, the way to the gym was short. When the gym doors finally came into view, several students let out quiet sighs of relief. The entrance had once been nothing more than the way to gym class or club practice; now it looked like the threshold to safety.
Euna ran ahead. She pressed her ear to the door, listened, then pushed it open and swept the interior. Wide wooden floor, tangled mats, equipment stacked along the walls. No zombies had wandered inside. “Come in.”
The students filed through one by one. The wounded entered first, followed by the rest. Juha and Eunjae guided the flow from either side while Chaewon stayed at the rear, counting heads. Haneul entered second to last, and Euna pulled the heavy door shut behind them. The metallic slam was heavier than expected. After the echo faded, the air inside felt separated from the world outside. The door would not hold forever, and the gym was no fortress, but for this moment at least there were no teeth snapping at their faces.
That single fact was enough. Students sank to the floor where they stood. Some covered their faces, others trembled with silent sobs, and a few simply stared blankly at the ground. Exhaustion, relief, and fear mingled on every expression.
Juha laid the student with the leg wound on a mat and checked the bandages, then examined the one whose arm had been splinted. Haneul moved to a corner and began wiping her blade. With each long stroke of the cloth, dried blood and sticky residue came away in dark streaks. She cleaned, inspected the edge, and held it to the light to check for nicks. The feeling of battle still lingered in her fingertips—sharper and more vivid than when she had fought alone. Leading others through danger felt unexpectedly exhilarating. Perhaps, without realizing it, she had always wanted to stand at the head of a group.
Chaewon counted the survivors once more. Four originals plus Eunjae and the students they had gathered. More people meant heavier responsibility. In the middle of that thought, Eunjae naturally took the center of the gym, where every eye could find her.
“Listen carefully.”
Scattered gazes turned toward her. Even the trembling and the dazed lifted their heads. Eunjae spoke in a steady voice.
“Our school is already finished.”
The words were brutally simple, yet no one could deny them. The blood and corpses in the classrooms, hallways, and stairwells had already proved it.
“Don’t expect the outside world to be any better. Don’t count on rescue.”
She cut away any lingering hope. Even as some students bit their lips or began to cry again, Eunjae did not stop. What they needed now was not vague optimism but a clear-eyed view of reality and the will to endure it.
“So we hold here. We move to survive. Lose focus and you die.”
The atmosphere inside the gym shifted. Despair did not vanish; if anything it grew heavier. But the shapeless terror had become a concrete task, and with that change came a sliver of clarity. Survival. That single, merciless rule was the only law left in this ruined world.
The students were facing reality for the first time. They still wept and trembled, but they were no longer shaking in ignorance. Inside this temporary shelter, with emergency supplies, Haneul clearing the way at the front, Chaewon and Eunjae keeping order, Euna standing watch, and Juha tending the wounded, a fragile community was beginning to take shape amid the wreckage of their school.
