The red LED on the rehearsal hall wall counted down thirty hours, blinking like an exposed vein.
Choi Tae-rin stayed fixed before the mixing console. His hand lingered near hers, knuckles almost brushing. "Tomorrow night," he murmured, his raspy baritone low enough that the overhead surveillance mics would register only ambient hum. "He’s rushing it because the resonance isn't stable. Because you aren't broken yet."
Min-jun pulled her sleeve over her thumb, tucking away the burner phone that vibrated against her hip. Three distinct pulses: Bae Su-jin’s distress code, converted to a ping. Fear was an unaffordable luxury. Her pride had kept her quiet in the beginning, convinced she could slip in, snatch her twin, and vanish without leaving footprints. That arrogance had evaporated.
"Get Ji-ho," she said.
A quarter hour later, behind the heavy acoustic baffles of the lower sound bay, the circle narrowed. Kwon Ji-ho stood by the heavy steel fire door, shoulders rigid, guarding the threshold. Beside him, Han Do-yun leaned against a flight case, his usual teasing smirk scrubbed completely raw. Ji-ho had laid out the surveillance logs, the forged contracts, the missing trainee registry—everything Min-jun had pulled from the basement server.
"A sacrificial lamb for the stock price," Do-yun said quietly, adjusting his practice vest. His amber eyes, usually so light and dismissive, fixed on Min-jun with surgical precision. "And here I thought you just forgot how to hit an aerial sweep on beat four. I owe you an apology, Min-jun-ssi."
"Keep it until we’re outside," she replied.
The burner lit up. A high-resolution blueprint pushed through an encrypted proxy, courtesy of Su-jin’s chaotic wizardry. It mapped the Grand Dome’s substructure: hydraulic lifts, ventilation labyrinths, and a sealed octagonal cavity directly beneath the main catwalk marked *Auxiliary Resonance Chamber*.
"That’s not an acoustic room," Ji-ho said, tracing the perimeter on the glass with an ink-stained thumb. "It’s completely isolated from the arena’s fire suppression system. It has independent atmospheric scrubbers."
"That's where he has her," Min-jun whispered.
Ji-ho stepped closer, his broad frame blocking the overhead lens entirely. "Do-yun and I take the stage-left security detail during the full-dress run at four. The venue staff report to external contractors; Omni’s internal guards only cover the perimeter lifts. Do-yun can short the relay for the south lift with a frequency cloner."
"And what happens when the director notices you aren't on your markers?" Min-jun asked.
Do-yun offered a thin, razor-sharp smile. "Ji-ho forgot his ear monitors. I went to fetch them. It buys four hundred heartbeats. In live production, that delay is an eternity."
"Don't get caught," she warned, her throat dry.
"Don't die down there," Ji-ho countered softly, catching her wrist for half a second. His grip was scorching through her thin fabric. "I let Haneul slip away once under my watch. I won't let it happen to either of you."

At four in the afternoon, the Grand Dome swallowed them whole.
The venue was an echoing cavern of black steel and violet rigs, thousands of empty bucket seats rising into synthetic darkness. The air tasted of ozone and dry ice. Below the catwalks, dozens of sound technicians scrambled over snaking cables while stage managers barked into headsets.
The agency director sat in the VIP command riser, suspended thirty feet above the floor like a spider in glass. His suit was immaculate, the silver pin of Omni Entertainment gleaming on his lapel.
"Take your positions," the stage manager shouted over the PA. "From the top of 'Celestia's Ascent.' Cue the descending platform!"
Min-jun stepped onto the polished acrylic disc at center stage. The fake jewels on her collar bit into the flesh of her collarbone. Across the risers, the youngest vocalist stood at his station. His cheeks were pale, his wide, guileless eyes darting toward her with silent anxiety. He held his wireless pack like a talisman, torn between the holy destiny he’d been fed for years and the terrifying reality unfolding around him.
The backing track roared to life—heavy synth pads, surging strings, an ominous sub-bass that rattled Min-jun’s ribcage. Tae-rin took his cue, spitting rhythmic fire into his gold-plated mic, his cadence sharp and vicious, but his eyes never left the command booth.
Then came Min-jun’s bar. The melody she had rewritten in the studio. The grief-stricken refrain that rejected the divine muse and spoke to blood and bone.
She opened her mouth, leaning into the head-voice transition.
*Pop.*
The feed died. Silence cleaved her voice in half.
Above them, the orchestral track faded into an ugly drone. From the elevated booth, the executive leaned over the balcony, holding a master wireless override. His expression was pitying, carved from cold porcelain.
"Cut the playback," the overseer's voice rolled through the arena monitors, smooth, condescending, amplified to deafening heights. "Stop the track."
The dancers halted mid-motion. The crew went dead silent.
"Look at our little miracle," Han chuckled, resting his elbows on the railing. "You see, gentlemen, raw passion only carries an amateur so far. Her voice is frayed. The spirit is cracked. Our dear muse’s inspiration has run dry before the sun even sets."
A technician snickered nervously near the wings. Min-jun stood under the harsh white rehearsal floods, stripped bare, the humiliation heavy enough to suffocate a lesser girl. Han wanted her shattered before the night fell; he wanted her compliant, desperate, willing to take whatever ritual drug or stage trick he offered to restore her supposed gift.
Min-jun kept her chin level. She gripped the cold aluminum stand and glared up into the glass booth.
From the shadow behind the percussion rig, Tae-rin kicked his monitor wedge aside. Without checking with the stage manager, he tapped his foot twice against the stage floor, caught the youngest vocalist’s panicked glance, and nodded once.
A savage, unscripted drum pattern ripped through the arena audio.
Tae-rin had plugged his personal audio sampler straight into the bypass jack. The beat was dirty, aggressive, stripped of Omni’s polished sheen. Tae-rin stepped to the lip of the platform, raising his mic.
"*You want a clean ghost, but the shadow won't sleep,*" he snarled into the mesh, the rhythm slamming down hard, uncompromising. "*Carve out the name, but the blood runs too deep!*"
Director Han straightened, his mask slipping. "Cut the house audio! Kill Tae-rin's channel!"
Before the technicians could touch the faders, the youngest singer lunged forward, throwing his full, pristine vocal power behind Tae-rin’s verse. The youngest vocalist was not crying anymore. The sweet boy’s voice soared, raw and blistering, lifting Min-jun’s forbidden harmony over the thunderous rhythm, bouncing off the rafters in open revolt. The entire crew froze, paralyzed by the sheer, illicit beauty of the mutiny.
"Kill it!" Han roared, slamming his clipboard against the console.
In the chaos of scrambled frequencies, Ji-ho met Min-jun’s gaze from the wings. He nodded, then broke toward the south corridor with Do-yun trailing at his heels to intercept the floor security.
The diversion was running. Two hundred heartbeats.
Min-jun dropped her dead microphone. The spotlight remained fixed on the center platform, blazing hot, isolating her in a single column of blinding white light amidst the dark arena. For one second, every instinct screamed at her to turn, find an exit door, and run out into the Seoul drizzle.
She turned her back on the light.
Dropping to her knees at the edge of the lift, she grabbed the manual release latch tucked under the acrylic lip and pulled. The maintenance hatch gave way with a hiss of pneumatic pressure. She slipped through the opening, letting the darkness below swallow her.
The fall was short, landing her boots onto the iron mesh of the catwalk sub-level. Alarms blared faintly above, muffled by concrete and steel. Tae-rin and the maknae were still shouting over the house speakers, holding the stage hostage with their noise.
Min-jun ran along the damp service duct, tracking the pipe markings from Su-jin’s floor plan. North-three. West-two. The smell shifted from machine grease to clinical antiseptic.
At the end of the narrow corridor stood an unmarked blast door, its electronic keypad ripped open, wires exposed where Ji-ho had bypassed the solenoid from the junction box.
She grabbed the manual dogging lever. Her muscles burned as she hauled it upward. The heavy seal broke with a wet hiss.
The door swung wide into a sterile, windowless white vault.
In the center of the room, slumped in a reinforced steel wheelchair beneath cold fluorescent tubes, sat Seo Haneul. An intravenous drip hung beside her, tubing taped to her pale arm, her breathing shallow and ragged under an oversized gray sweater.
Haneul lifted her head. Her sunken eyes struggled to focus against the glare, her lips parting in disbelief.
"Min-jun?" she croaked.
