The Last Bell

Chapter 4

The storage room didn't just groan; it shrieked. The metal shelves, laden with decades of neglected curriculum, shuddered as the floorboards buckled upward like a surfacing leviathan. Dust, thick and choking, rained down from the ceiling, illuminated by the dying, flicking fluorescent lights.

Ye-jun didn't look back at So-ra. He knew that if he stopped, if he tried to convince her, the ceiling would decide the matter for them. He lunged at the door, his shoulder catching the wood with a jarring, bone-deep impact. It didn't budge.

"It’s jammed!" Ye-jun yelled, his voice strained by the encroaching pressure.

He didn't wait for her response. He grabbed a heavy metal supply crate and swung it with every ounce of kinetic energy he could muster. The wood splintered. He didn't care about the splintering wood; he jammed his fingers into the jagged gap and pulled, his skin tearing against a stray nail. He kicked the door until the lock gave way, spilling him out into the hallway.

He spun around to grab So-ra, but she was already moving, her face a mask of primal terror. They scrambled into the corridor just as the storage room behind them imploded, a sound like a gunshot echoing through the empty, twilight-shadowed school.

"Run!" Ye-jun commanded, grabbing her arm.

They didn't stop until they reached the sanctuary of the science wing, specifically the advanced laboratory where Han Seojin spent her afternoons. The door was locked, but Ye-jun didn't hesitate. He hammered on the reinforced glass.

Seojin looked up from a complex array of monitors and copper wiring, her expression one of annoyance, which vanished the moment she saw the state they were in. She unlocked the door instantly.

"What in the world are you two doing?" Seojin demanded, pulling them inside. "You look like you crawled out of a demolition site."

Ye-jun locked the lab door behind them, his breath hitching in his chest. "Seojin, we don't have time. The school—it’s repeating. It’s killing us, and it’s moving, changing the variables every time we try to stop it."

Seojin blinked, her eyes darting between them. She wasn't one for panic; she was one for data. She walked over to her primary terminal, her fingers flying across the keys. "I’ve noticed the flux. The electromagnetic interference in this building has spiked three times today to levels that shouldn't be physically possible. It’s like the building is rebooting its own localized reality."

"Can you prove it?" So-ra asked, leaning against the lab table, her hand still trembling.

"I’ve been tracking the clock sync," Seojin said, gesturing to a monitor displaying a waveform. "Every single 'accident' today, and in the last few cycles I’ve observed, the school’s master clock freezes for exactly seven seconds. It’s not a malfunction. It’s a buffer. Something is calculating the next death."

Ye-jun stared at the screen. The waveform was beautiful, terrifyingly precise. "Seven seconds. That’s our window."

"A window for what?" Seojin asked. "If the system is already locked on a target, how do you change the output?"

"By changing the input," Ye-jun replied. He looked at So-ra, then at the equipment lining the room. "We need to track the energy. If this is a machine, a simulation, or some kind of temporal trap, it has to be running on something. Where is the signal coming from?"

Seojin nodded, her eyes hardening. She hooked a handheld sensor to a local server rack. "I’ve been tracing the bypass signals. They aren't coming from the main office. They’re coming from the security hub in the basement. But that area is restricted, and honestly, the sheer volume of data being pushed through the CCTV network is absurd. It’s like the cameras aren't just watching us—they’re recording alternate timelines."

"Show us," Ye-jun said.

Seojin tapped a sequence into her console. A grid of screens flickered to life. The footage showed the school, but it was wrong. In one frame, the hallway was flooded with water. In another, it was ablaze.

"Look," Seojin pointed to a specific file. "This is from the 17:23 event that just occurred in the library. I pulled the archive cache."

Ye-jun leaned forward, his eidetic memory bracing for the impact. The footage played. It showed the library hallway. The girl he had tried to save was walking toward the center of the frame. Then, the screen flickered.

Ye-jun’s blood turned to ice.

In the footage, a figure emerged from the shadows of the adjacent classroom. It was him. Seo Ye-jun. He was walking toward the girl with a detached, cold expression, his hand raised as if pulling an invisible trigger. The girl collapsed. He didn't blink. He just watched, his face unreadable, before vanishing into thin air.

"That’s... that’s not me," Ye-jun whispered, his voice trembling. "I was in the chemistry lab. I was with Ji-hoon. I have an alibi!"

"Look at the timestamp," So-ra said, her voice dropping to a hollow whisper. "It says 17:23."

"I was in the lab at 17:23!" Ye-jun shouted, pacing the small, claustrophobic space. "I locked the door! You were with me, So-ra!"

"The footage is authentic, Ye-jun," Seojin said, her voice devoid of its usual clinical detachment. She zoomed in on the figure’s face. It was undeniably him. The scar on his chin, the way he held his left shoulder—it was perfect. "There’s no glitch here. The system isn't just recording events. It’s creating evidence."

Ye-jun felt the room closing in. The walls, the monitors, the sterile smell of chemicals—it all felt like a trap designed specifically for him.

"Why?" he rasped. "Why frame me?"

"Because you’re the anchor," So-ra said, stepping away from him. She pulled out the note she had found earlier, the one that accused him of facilitating the deaths. "This isn't a game, Ye-jun. It’s a trial. And if the system has already decided you’re the culprit, then maybe the only way to stop the loop is to remove the primary variable."

"You think I’m doing this?" Ye-jun looked at her, his eyes wide. "You’ve seen me fight to stop it! You’ve seen me die in these loops too!"

"Maybe that’s just what you want us to see," Seojin murmured, her fingers hovering over a command line. "If the cameras show you there, but you’re physically elsewhere, the system isn't just manipulating time. It’s manipulating perception. It’s making us believe you’re the killer so that we turn on each other."

A piercing, distorted alarm began to sound—not from the speakers, but from the very air around them. It was a rhythmic, pulsing throb that mirrored the 17:23 countdown.

Tick. Tick. Tick.

"It’s happening again," Seojin yelled over the noise. "The buffer! We have seven seconds!"

Ye-jun looked at the monitors. The view in the chemistry lab—where they were—shifted. He saw himself standing at the lab bench, holding a beaker. But in the footage, his hand was shaking, and he was staring at the door with a terrifying, hollow malice.

"I'm not doing that!" Ye-jun screamed.

He didn't wait for them to argue. He grabbed a heavy wrench from Seojin’s table and swung it at the server bank, desperate to break the connection, to stop the loop from writing its own false history.

As the metal impacted the glass, a blinding, white light erupted from the monitors. The sound of a thousand clocks ticking in unison filled the room.

Ye-jun felt his body being pulled forward, his vision warping into a tunnel of light. As he hit the floor, his last sensation was the feeling of his own hand, in the reflection of the screen, reaching out from the digital void to grab his throat.

17:23.

The world dissolved into the black, silent void.

Tick.

Ye-jun gasped, his eyes flying open. He was back in his desk. The fluorescent lights hummed. The smell of floor wax was thick in his nostrils.

"Yo, Ye-jun, you okay? You look like you’ve seen a ghost," Lee Ji-hwan remarked, leaning back in his chair.

Ye-jun didn't look at him. He looked at his own hands. They were trembling. He turned his head to the side.

There, on his own desk, sat a small, crumpled piece of paper that hadn't been there a second ago. He unfolded it with shaking fingers.

The footage was a preview. The next death is yours, and everyone will see you do it.

Ye-jun looked up, his heart hammering against his ribs. He looked at Seojin, who was currently staring at her tablet, her face pale as a sheet. She looked up and locked eyes with him, her expression one of dawning, absolute horror.

"Ye-jun," she whispered, her voice barely audible. "I just checked the server logs. The footage of you... it wasn't a recording. It was a live feed."

The classroom door began to slowly, agonizingly creak open. Ye-jun turned his head. Standing there, in the doorway, was himself. His double. The version from the footage, holding a knife, with eyes as hollow as the void itself.

The clock above the door began to tick down.

17:22:50.

The race to survive had just become a war against his own reflection.
