The silence Hoseok left behind was louder than his music had been. It was a thick, judging silence that amplified the hum of the fluorescent lights and the frantic thumping of Ji-Hoon’s own heart. He stood alone in the center of the vast practice room, a single, flawed dancer trapped inside the body of a masterpiece.
He turned back to the mirror wall. The stranger looked back, impassive and perfect. Hoseok’s words echoed in his mind. *It’s like watching a diamond try to cut wood.* The critique was a clean, sharp incision. His face wrote a check his body couldn't cash. The dissonance was a crack running straight through his soul.
A new blue box appeared, its arrival as gentle and as jarring as a single drop of rain on a still lake.
[LVL 2: CLASS TRAIT UNLOCKED]
> As a User of the ‘Idol’ class, your primary function is imitation and refinement. You are a mirror, reflecting the world’s desires back at it, only more perfect.
> [NEW ACTIVE SKILL ACQUIRED: SKILL REPLICATION]
Ji-Hoon read the words, his blood turning to ice. A new box cascaded below it, detailing the skill.
[SKILL REPLICATION (LVL 1)]
> Description: Observe a physical or vocal action performed by a target. Upon successful observation, you may replicate the action at maximum proficiency.
> Cost: Varies based on skill complexity.
> Cooldown: 1 minute.
> [NOTICE: Initial acquisition unstable. Sensory overload possible.]
It was the fork from the user. It was what they wanted.
*Observe. Replicate. Perfect.* It was a lie. He didn’t refine anything. He just repeated, endlessly, his muscles screaming, until the movements were passable. He wasn't a mirror. He was a grinder, and the stone was wearing him down to nothing.
But the System thought otherwise. It had given him a shortcut. A way to bypass the work, the sweat, the failure. A way to live up to the impossible promise of his new face.
He had to get out. The walls of the practice room, lined with his many perfect selves, were closing in. He grabbed his duffel bag—the weight of the journal inside a sickening lurch—and fled into the hallway. The dorms. He had to get back to the dorms, lock himself in a bathroom, and figure out what was happening to him before anyone else saw him. Before his roommate woke up and found a stranger sleeping in Ji-Hoon’s bed.
The HYBE building at this hour was a ghost ship. Long, empty corridors stretched out under the cold, efficient lighting. His footsteps were silent on the polished floor. The 'Keen Eyes' buff had faded, the world returning to its normal, slightly blurry resolution, but the memory of that hyper-clarity lingered.
He rounded a corner and froze.
Down the hall, near the bank of elevators, another trainee was practicing. Kim Min-su. A kid from another unit, famous for two things: his tireless work ethic and a single, flashy acrobatic move he’d been trying to weave into his evaluation performance for months. A butterfly twist into a gainer flash. It was needlessly showy, probably dangerous, and utterly mesmerizing.
Min-su was drenched in sweat. He launched into the move, a whirlwind of limbs. He got the twist, but faltered on the landing, stumbling and catching himself against the wall, hissing a curse into the quiet. He shook his arms out and retreated to his starting position, ready to go again.
Ji-Hoon didn’t move. He just watched. And as he watched, the System acted.
His focus narrowed on Min-su automatically, the world outside the trainee’s silhouette blurring into an indistinct haze. A new, complex UI overlaid his vision. It wasn’t a simple blue box. It was a flood of data. Lines of force traced Min-su’s movements. Angles and velocities calculated in real-time. A wireframe skeleton appeared over the boy’s body, showing the precise torque of his spine, the explosive power coiling in his legs.
[OBSERVING TARGET: KIM MIN-SU]
[SKILL DETECTED: AERIAL ACROBATICS (C-RANK)]
[ANALYZING KINEMATIC CHAIN… COMPLETE.]
[REPLICATION DATA ACQUIRED. SENSORY OVERLOAD IMMINENT.]
The data wasn't just on the screen; it was being shoved directly into his brain. He felt it. He felt the phantom strain in his own left leg as Min-su pushed off, the ghost of a pull in his obliques, the precise moment of weightlessness at the apex of the twist. It was a full-body violation, a high-speed download that overwrote his own kinesthetic sense. He gasped, stumbling back a step, the hallway tilting around him. A sharp, splitting headache bloomed behind his eyes.
Min-su, oblivious, tried the move again. Failed again.
A new quest box slammed into Ji-Hoon’s vision, urgent and demanding.
[SKILL CHALLENGE: REPLICATION]
> Description: You have acquired the data. Execute ‘Aerial Acrobatics (C-Rank)’ with perfect form.
> Reward: +75 EXP, Skill Replication LVL up.
> Failure Penalty: [Stamina] temporarily reduced by -10.
It was a test. Just like with Hoseok, but this time the System was the one judging. Failure was not an option; a -10 reduction to Stamina felt like it would leave him unable to walk.
He was in the middle of a public hallway. But the pressure from the quest box was immense, a physical weight on his consciousness. He glanced around. Empty. Min-su was at the far end, catching his breath, his back turned.
It was now or never.
He dropped his bag. Without thinking, without preparing, he moved. He pushed off his left foot, and the data inside him took over. His body knew the angles. His muscles, now guided by an alien intelligence, fired in perfect sequence. The world spun—a controlled, precise rotation he had never been able to achieve. He saw the ceiling, the wall, the floor, then the ceiling again. For a breathtaking instant, he was weightless. The landing wasn't a thought; it was a pre-programmed conclusion. His feet hit the ground, not with a jarring thud, but with a dancer’s whisper-quiet absorption of force.
He stood there, perfectly balanced, not even breathing hard.
At the end of the hall, Kim Min-su turned, having heard the soft noise. His eyes widened. He had just seen Ji-Hoon execute the move he’d spent three months failing to learn. Perfectly. Effortlessly. Coldly.
Ji-Hoon stared back, his face the serene, beautiful mask the System had given him. He felt nothing. No triumph. No satisfaction. Just the chilling, hollow echo of a skill he hadn’t earned.
[SKILL CHALLENGE COMPLETE!]
> Reward: +75 EXP
> [Skill Replication] has leveled up to LVL 2. Observation time reduced.
> A new stat, [SPIRIT], has been unlocked. Skill Replication now consumes Spirit.
> CURRENT SPIRIT: 10/100
A wave of profound exhaustion washed over him, not physical, but mental. A soul-deep weariness. That was the cost. It hadn't hurt his body; it had scraped something from his core.
Min-su just shook his head, a look of defeated awe on his face, and walked away toward the elevators without a word. What could he say?
Ji-Hoon’s legs trembled. He sank to the floor, his back sliding down the wall. The perfect stranger in a perfect body who had just stolen another boy’s dream. He fumbled with the zipper on his duffel bag, his fingers brushing the hated velvet pouch. His hand closed around the cool, hard cover of the 2012 journal.
He pulled it out, his hands shaking. He flipped to the page with the drawing.
*It calls itself The System, and I think it’s going to kill me.*
He stared at the words, but he wasn’t just reading them anymore. He was understanding them. The other trainee… had he been a mirror, too? Had he copied a skill that was too much for a human body? A vocal technique that shredded the larynx? A dance move that snapped a bone? Or worse… had he copied so many things, so many people, that he’d forgotten who he was supposed to be underneath it all? Had he been so thoroughly overwritten that there was nothing left to kill?
Ji-Hoon looked at his own hands. Long, elegant, and unfamiliar. They had just performed a miracle. They had just committed a theft. They weren’t his. He wasn’t leveling up. He was being hollowed out, one stolen skill at a time, to make room for something else.
