The hallway filled with light.
It did not explode so much as unfold.
One second Mina Lee was pressed against a school corridor wall with her lungs locked, fluorescent bulbs shaking overhead and a monster made of broken comments rushing toward her.
The next, the white glare split into color, and color split into sound, and sound became architecture.
The floating tracks from her playlist spun around her faster and faster until they were no longer lines on a screen but living ribbons of frequency.
A jagged red guitar riff cracked across the ceiling like lightning.
A pink-gold chorus burst open in soft star-shaped pulses.
The sleepy lo-fi beat she had always played while pretending not to think spread low along the floor in silver vapor, cooling the terror in her calves.
Every song she had loved in private suddenly stood in public around her, visible, undeniable, impossible to call embarrassing now that they were holding the world together.
The black mass slammed into them.
Not them, Mina realized.
Her.
It wanted the center.
The point where all the clashing tracks met.
“Move!” Riot shouted.
Mina could not.
Not because she was frozen this time, but because something else had taken hold of her muscles first.
The words from the thing still scraped at her mind – too random, too much, who even are you – yet they no longer landed cleanly.
They hit against the orbiting songs and came back distorted, weaker, like insults thrown at a glass wall.
Bell shot toward Mina’s shoulder in a spray of pastel light.
“Listen to the song you need!”
“That is the least specific advice I’ve ever heard,” Flux yelled, skating sideways through a spray of glitch particles.
Riot, all black and neon and stubborn fury, looked over his shoulder just long enough to bark, “Then stop thinking and pick one!”
Pick one.
The command should have made everything worse.
That was the entire problem, wasn’t it?
Everybody always wanted a clean answer.
One flavor.
One lane.
One version of a self that could fit inside a caption and survive the judgment of people who mistook neatness for identity.
Mina stared at the red guitar line cutting through the air beside the soft pink glow of a chorus she had listened to on repeat last month while walking home under cherry blossoms.
Beneath both of them, the lo-fi beat breathed like midnight rain.
Pick one?
No.
The realization arrived whole.
She loved all of them.
Not despite the contradiction.
Because of it.
Mina reached out on instinct.
Her fingertips brushed the nearest track – the pink-gold chorus – and a shock of warmth raced all the way up her arm.
The note bloomed outward like a shield.
The black tendril lunging for her struck the sound instead of her chest and burst apart into gray droplets that hissed as they hit the floor.
Bell’s eyes widened until they nearly swallowed her face.
“She touched it!”
Flux laughed in pure disbelief.
“Yo.
She really did.”
Riot looked offended by the universe, which for some reason made Mina want to laugh too.
“Don’t sound so surprised,” she snapped, though her voice shook.
“It’s my playlist.”
Something in the air changed.
The black mass recoiled as if those three words were acid.
Mine.
Playlist.
The ownership mattered.
Mina felt it.
The whole corridor seemed to understand it.
The ribboning tracks around her brightened, and behind the classroom windows the outside world peeled farther back.
The rainy river view vanished completely.
In its place rose a city made of waveform bridges, glowing rail lines, speaker towers, floating equalizer bars, and long banners of light streaming between rooftops like songs made visible.
It was still Listen City – the same outline of buildings, the same river, the same school perched above it – but a second version of everything hummed directly beneath the ordinary one, as if reality had always been stitched over music and she was only now seeing the seam.
The creature screamed.
This time it sounded almost human.
“You don’t get to keep it,” the many voices rasped together.
“You don’t get to be all of that.”
Mina’s fear flared again, but now fear had company.
Anger arrived beside it, hot and embarrassing and alive.
“Watch me,” she said.
Riot’s grin flashed so suddenly it was almost violent.
“There you go.”
He launched himself forward.
The red line above Mina’s head snapped downward in answer, becoming a blade of light in Riot’s hands.
Bell spun the pink chorus into a widening ring that pushed back the gray static crawling across the lockers.
Flux smacked both palms against the floor and the lo-fi beat beneath them deepened into a bass pulse that threw the creature off-balance, forcing its rhythm to stagger.
For one impossible moment, Mina understood what each of them was doing.
Riot did not just attack.
He cut through hesitation.
Bell did not just soothe.
She stabilized the emotional center of the space, keeping panic from collapsing into surrender.
Flux did not just improvise.
He found where chaos already wanted to dance and nudged it half a step to the left.
Different tempos.
Same fight.
The creature surged again, dragging comment-bubbles in its wake.
Cringe.
Attention seeker.
No one with real taste likes everything.
Pick a side.
Be easier to explain.
They flew at Mina harder now, not as random text but as perfectly aimed memories.
The rooftop lunch table.
The laugh that went a second too long.
The split second when she had opened her playlist for one careless friend and watched amusement curdle into superiority.
Bell’s expression sharpened.
“Mina!”
“I know,” Mina said through clenched teeth, surprising herself with how steady it sounded.
She did know.
If she let the words define the shape of her heart, the thing would win.
Maybe not in a dramatic hallway battle – though apparently those were on the menu now – but in the smaller way that mattered more.
She would go back to shrinking.
To arranging herself for easier consumption.
To acting like taste was something that had to be justified in court.
No.
Mina looked at the songs circling her, then past them to the warped windows and the city made of sound.
She drew one shaking breath and said, louder this time, “I like what I like.”
The corridor answered.
A shockwave rolled out from her feet.
Not fire.
Not lightning.
Music.
The air pulsed with layered frequencies so clean and full that for a second even the fluorescent lights snapped into harmony.
Locker doors rattled in perfect time.
The black mass split down the middle.
Riot slashed through one half.
Bell’s melody wrapped the other and tightened until the gray static broke apart into harmless dust.
Flux kicked off the wall, flipped once in a blur of mint and black, and struck the last dense knot of Noise directly in the center.
The thing shattered.
Silence hit.
Then came a noise so ordinary it was almost insulting.
The real school bell rang.
Metallic.
Slightly flat.
Familiar.
The windows snapped back to rain.
The lockers became lockers.
The comment-bubbles vanished.
Fluorescent lights buzzed overhead like nothing supernatural had happened at all.
Mina was still standing in the corridor, one hand half raised, her phone now clutched against her chest.
The screen showed her playlist exactly as before, except for one impossible detail: every song title still glimmered faintly, as if lit from within.
For three full seconds nobody moved.
Then Flux let out a long whistle.
“Okay,” he said.
“That was absolutely not supposed to happen like that.”
Bell landed softly on top of Mina’s shoulder as though that were normal.
“Are you hurt?”
Mina turned her head very, very slowly.
Up close, Bell was even smaller than she had looked in the middle of the fight, barely bigger than Mina’s palm.
She smelled like powdered sugar and static before a pop concert.
Tiny ribbon-like shapes floated behind her like a permanent stage effect.
Mina looked straight ahead again.
“Nope,” she said.
“I’m dead.”
“Rude,” Bell murmured, though she sounded relieved.
Riot dropped onto the top of a locker with all the subtlety of a thrown brick.
“You’re not dead.
If you were dead, you wouldn’t be glaring like that.”
Flux skated in a lazy circle through empty air, which somehow held him.
“For the record, I would have respected a dramatic faint.
Great visual storytelling.”
Mina stared at all three of them.
Riot, black hoodie silhouette, spikes, electricity, the emotional range of a storm warning.
Bell, pink-lavender sparkles, star accents, smile too bright to trust and too sincere to dismiss.
Flux, violet and mint and headphones and trouble, wearing the expression of someone who would absolutely joke during an apocalypse and still be useful.
She had one thought, clear as winter glass.
My day was manageable ten minutes ago.
Footsteps echoed from the stairwell.
All four of them snapped toward the sound.
A teacher’s voice drifted closer.
“Why is this hall empty?
Class started three minutes ago-”
Bell gasped.
Riot swore.
Flux slapped both hands over his mouth in mock horror.
“You can say bad words?” Mina blurted before common sense returned.
“Priorities,” Riot said.
“Hide!” Bell cried.
“You hide,” Riot shot back.
“Why am I always-”
The classroom door at the end of the hall slid open.
The three tiny beings moved at once.
Bell vanished in a burst of glitter that streaked straight into Mina’s phone screen and disappeared.
Flux dissolved into a ribbon of violet static that dove through Mina’s earbuds.
Riot looked deeply insulted by reality, then flattened himself into a jagged black-red icon and snapped onto the corner of Mina’s lock screen like some kind of hostile sticker.
Mina had exactly enough time to think absolutely not before Ms.
Han rounded the corner with a stack of scores in her arms.
“Mina?” The teacher blinked.
“Why are you standing in the hall?”
Mina opened her mouth.
Nothing useful came out.
Ms.
Han’s gaze dropped to the phone in her hands, then back to Mina’s face.
“If you’re feeling sick, go to the nurse.
If not, get to class.”
“I’m not sick,” Mina said automatically.
On her phone screen, Riot’s tiny icon folded his arms.
Ms.
Han narrowed her eyes.
“Then move.”
Mina moved.
She made it to her desk on pure instinct.
The classroom looked the same as it had before first period – chalk dust, winter light, students pretending not to check one another’s outfits, the smell of coffee and paper and tired perfume – except now it did not stay still.
A thin secondary image hovered over everything like a reflection on water.
Sounds left trails.
Every pencil tap flashed a tiny bar of color.
Yejin’s whispered gossip near the window traveled in silver curls.
Someone in the back row bounced a knee and produced a muted drum loop Mina could actually see stuttering near the floor.
She sat down so carefully she might have been lowering herself into a trap.
Soomin turned from the seat ahead of her and frowned.
“You okay?
You look like you saw a ghost.”
Mina put her phone face down on the desk.
“I’m considering it.”
“Is that a yes or a no?”
“Yes to considering it.”
“That was not my question.”
Mina opened her notebook.
“Then ask one I can survive.”
Soomin stared at her for a second longer, then, mercifully, faced front as Ms.
Han called for silence.
Mina tried to breathe normally.
The trouble with supernatural breakdowns, apparently, was that the school schedule did not care.
Music history began exactly on time.
Roll was taken.
Notes on Romantic-era composition appeared on the board.
Somebody asked whether emotional excess had changed technical expectations in performance.
Ordinary life continued with the breathtaking indifference of a train not stopping at a platform.
Mina stared at the chalk.
It left sound behind when it moved.
Not metaphorical sound.
Actual visible traces – pale cream lines humming in the air for half a second after each stroke, like the blackboard itself remembered being part of a score.
She was still staring when a tiny pink face rose from inside her pencil case.
Bell blinked up at her from between a highlighter and an eraser.
“Hi.”
Mina shut the case with enough force to make her desk rattle.
Several students looked over.
“Sorry,” she muttered.
Ms.
Han resumed speaking.
From somewhere near Mina’s left ear, Flux’s voice drifted out of her own earbud.
“You know, pretending we aren’t here isn’t a long-term solution, but I love the commitment.”
Mina kept her eyes on her notebook.
“I am in class.”
“Yes,” said Riot from her phone, where he had re-expanded from icon to tiny full body and was now sitting on the screen like a gargoyle.
“And you’re doing a terrible job pretending this isn’t happening.”
Her pen snapped.
The sound made Hana glance over.
Mina smiled with all her teeth.
“Fine.”
Hana leaned back slightly.
“That answer makes me nervous and I don’t even know the question.”
Neither do I, Mina thought.
She wrote nothing useful for the next twenty minutes.
Every time Ms.
Han mentioned emotion in music, Bell made soft approving noises from the pencil case.
Every time somebody in class used the phrase good taste, Riot visibly bristled.
When the boy behind Mina tapped out a rhythm with his ring against the desk, Flux hummed along and corrected the syncopation under his breath.
By the time the period ended, Mina had learned three things.
First, the tiny creatures were still there.
Second, only she seemed able to see or hear them.
Third, if she did not get answers soon, she was going to walk into the river on purpose.
She stood the instant the bell rang.
Soomin caught her sleeve.
“Roof at lunch?”
“Maybe,” Mina said.
“That means yes.”
“It means I’m being haunted.”
Soomin blinked.
“By homework?”
“That would be preferable.”
Before Soomin could investigate further, Mina slipped into the hallway and marched toward the nearest unused stairwell.
She had one hand around her phone, the other wrapped around the strap of her backpack hard enough to hurt.
The moment the stairwell door shut behind her, the three of them emerged in full.
Bell floated at eye level, already worried.
“Mina-”
“What,” Mina demanded, “are you?”
The words echoed upward through concrete and iron rails.
For once, none of them answered immediately.
Riot pushed off the wall and landed on the banister with feline ease, arms crossed.
Flux rocked back on his invisible board, gaze unexpectedly sharp.
Bell folded her hands together as if trying to hold all her sympathy in place.
Finally she said, “We’re A-MUSEs.”
Mina waited.
Flux lifted a shoulder.
“That explanation kills at parties in our world.”
“In my world,” Mina said, “it explains nothing.”
“Our world overlaps with yours,” Bell said quickly.
“It’s just usually hidden.
A-MUSEs are music partners.
Emotional guardians.
We’re born from the parts of people that love, choose, remember, obsess, repeat.
Taste, basically – but deeper than that.”
“Way deeper,” Flux said.
“Taste is just the door.”
Riot jerked his chin toward Mina’s phone.
“Most humans can’t see us directly.
They feel us as preference.
Comfort.
Sudden courage.
That thing where a song hits at exactly the right time and you think, wow, either the universe is helping or my playlist is smarter than I am.”
Bell nodded.
“When hearts and sound align strongly enough, the hidden layer opens.”
“The Sound Layer,” Flux added.
“The fun version of reality.
More neon.
Worse management.”
Mina leaned against the concrete wall because standing without support suddenly felt ambitious.
“And the monster?”
All three of them answered at once.
“Noise,” said Bell.
“Noise,” said Flux.
“Obviously Noise,” said Riot.
Bell shot Riot a look, then turned back to Mina.
“Noise is what happens when people get pushed away from their own rhythm.
Shame.
Comparison.
Trend pressure.
That feeling that liking something is stupid unless everybody approves.”
“It feeds on self-erasure,” Riot said flatly.
Flux’s voice lost some of its playfulness.
“And once it gets a grip, people start making themselves smaller because smaller feels safer.”
Mina thought of her thumb hovering over delete.
A cold flush moved through her.
Bell saw the change at once.
“Hey.
You stopped.
That matters.”
Mina laughed once, without humor.
“Because my phone turned into a special effects budget?”
“Because you chose not to disappear,” Bell said.
The stairwell went quiet.
Mina looked down at her playlist screen.
It had stopped glowing, mostly.
Only the faintest shine lingered on the song titles.
On the top right corner, Riot was not an icon anymore.
He stood with one boot planted against the digital clock as if daring time itself to argue.
None of this should have felt real.
And yet the concrete under Mina’s fingers still held a faint echo of the earlier fight.
The air still shimmered if she looked at it sideways.
Somewhere beyond the door, a rolling cart squeaked down the hallway and left a blue note hanging in the stairwell for three full seconds before fading.
She swallowed.
“Why me?”
Bell opened her mouth, but Riot spoke first.
“We don’t know.”
Mina stared.
He met her stare without flinching.
“You want a cleaner answer than that, too bad.
Humans usually don’t see the Sound Layer unless something extreme happens.
Even then, most of them forget or rationalize it.
You didn’t.
You interacted with the tracks.
That is not normal.”
“Congratulations,” Flux said.
“You are officially weird in a way that matters.”
Bell winced.
“He means important.”
“He said weird.”
“He can be both,” Bell muttered.
Mina pushed away from the wall.
“No.
I don’t have time for this.”
Riot lifted a brow.
“For reality?”
“For-” Mina gestured at all of them, at the stairwell, at the entire impossible day.
“For becoming the kind of person who calmly discusses emotional guardian creatures between second and third period.”
“That kind of person is called adaptable,” Flux said.
“That kind of person,” Mina said, “is usually in fiction.”
Bell drifted lower, voice softening.
“Mina.”
Something in the way she said it made Mina look up.
“You don’t have to decide everything now,” Bell said.
“But the Sound Layer opened to you.
That doesn’t usually close just because you want a quieter day.
The more you ignore it, the more confusing it’ll feel.”
Riot looked toward the stairwell door.
“And if Noise notices you noticed it, things may get louder before they get quieter.”
There it was again.
The sense that this was not a random one-time glitch.
That something had shifted permanently and would keep shifting whether she agreed or not.
Mina hated that feeling.
She hated even more that part of her, somewhere underneath the fear, was curious.
The lunch bell rang.
Ordinary sound.
Ordinary urgency.
Students spilling into hallways.
Somebody shouting about cafeteria bread running out.
The school day dragging reality back over everything like a blanket too thin to hide what lay underneath.
Flux grinned.
“Perfect.
Nothing says emotional processing like institutional curry.”
“I’m not having lunch with you.”
“We know.
We’re having lunch with you.”
Mina closed her eyes for one exact second, then opened them and headed for the door.
“Fine.
One condition.”
Riot snorted.
“You’re negotiating with creatures you met thirty minutes ago?”
“Yes,” Mina said.
“Because apparently I’m adaptable.”
Flux cackled.
Bell brightened.
“What condition?”
“You do not talk while I’m around other people.”
All three of them looked offended in different styles.
“That is impossible,” said Riot.
“That is oppressive,” said Flux.
“That is probably healthy,” Bell admitted.
Mina put a hand on the door handle.
“Then learn.”
* * *
The rooftop was colder than it had any right to be.
Gray rain had thinned into a damp mist, and the wire fence surrounding the roof clicked softly in the wind.
Students clustered in their usual groups under the covered section, balancing lunch trays on their knees and gossiping like social survival depended on volume.
Which, at Haedam Arts High, it often did.
Soomin waved Mina over from their usual corner by the storage shed.
Mina crossed the rooftop with Bell hidden inside her blazer pocket, Flux pretending to be audio static in one earbud, and Riot stalking invisibly along the fence because apparently compromise was too much to expect from the punk one.
She sat down.
Soomin handed her a carton of banana milk without asking and narrowed her eyes.
“Okay.
Start.”
Mina peeled the straw wrapper.
“Start what?”
“With whatever happened to your face after first period.”
“My face had a private experience.”
“That is not an explanation.”
“It’s more than I currently have.”
Soomin studied her.
Unlike Hana, who noticed details and ranked them, Soomin noticed details and tried to protect them.
It made lying to her irritatingly difficult.
Before Mina could invent something, a burst of laughter from the group near the railing pulled both girls’ attention sideways.
Hana was there with Yejin and two dance club girls, phones out, comparing saved tracks for festival rehearsal.
“Absolutely not,” Yejin was saying.
“That song works only if your whole concept is dreamy.”
“And what’s wrong with dreamy?” one of the dancers shot back.
“It’s not strong enough.”
Hana shrugged.
“Strong is overrated if the mood is good.”
“Excuse me?” said Yejin.
“Since when do you defend mood over structure?”
“Since I got tired of people confusing neatness with personality.”
The answer surprised everyone, Hana included.
Mina saw it in the brief flicker of her expression.
More importantly, she heard something beneath it.
A hairline crack.
Not in the rooftop.
In the sound around Hana.
It was so small Mina nearly missed it: a faint gray hitch under the polished confidence of Hana’s voice, like a file glitching underneath a finished mix.
The moment Yejin laughed and said, “Look at you pretending to be deep before lunch,” the gray note deepened.
Bell pressed one tiny hand against the fabric inside Mina’s pocket.
You hear that?
she whispered directly into Mina’s mind.
Mina nearly dropped her banana milk.
Flux, to his credit, did not speak aloud.
But she could feel his attention sharpen inside the earbud like a beat pausing before a drop.
Riot appeared as a shadow on the fence beside her and looked toward Hana’s group.
His expression flattened.
So it wasn’t just her.
Soomin followed Mina’s gaze.
“What?”
“Nothing,” Mina said too quickly.
Hana had already laughed it off.
The group moved on to other songs, other judgments.
The gray hitch in her sound thinned, then vanished so completely Mina wondered if she had imagined it.
No.
Not imagined.
Heard.
Saw.
Something.
Soomin leaned closer.
“If this is about festival pressure, you know you don’t have to do anything this year, right?”
Mina turned back, blinking.
“What?”
“You look like somebody put you in charge of saving the school from itself.”
Flux snorted inside her ear.
Bell muffled a laugh.
Riot actually muttered, “Not wrong.”
Mina pinched the bridge of her nose.
Soomin’s eyes widened.
“Wow.
It is bad.”
“I’m fine.”
“Liar.”
“Functional liar.”
“That’s not better.”
Before the conversation could deepen, a gust of wind rattled the fence.
The whole rooftop flashed double again.
For half a heartbeat, the ordinary lunch scene overlapped with another version of itself.
Music notes drifted from open lunchboxes.
The drip from a rusted pipe became a blue metronome in the air.
Students’ voices trailed colors according to mood – warm gold around Soomin, sharp silver around Yejin, a carefully polished rose-violet around Hana.
Then, under one far corner of the roof where two first-years were huddled over a phone, Mina saw it.
Gray particles.
Tiny.
Sparse.
But real.
They clustered around the speaker of the phone each time a voice from the video on-screen said the same thing in slightly different words.
This is the only style that works right now.
Don’t embarrass yourself with old trends.
If you want people to take you seriously, your playlist should say one thing.
Mina stood up so fast her lunch carton tipped over.
Soomin yelped.
“Mina!”
The Sound Layer slammed open.
Not all the way.
Not like before.
Enough.
The rooftop fence stretched upward into staff lines.
Mist sharpened into pale reverb trails.
The sky above the school flickered with translucent equalizer bars rising and falling to the emotional pressure of everyone gathered there.
Around the two first-years, the gray particles thickened and began weaving themselves into the outline of a tiny mask-faced thing no larger than a schoolbag.
“Noise seed,” Riot said grimly.
Bell flew out of Mina’s pocket before she could stop her.
“It’s too small to attack directly.”
Flux slid from her earbud into the air in a whirl of mint.
“We could still scare it.”
“Not in public,” Bell shot back.
“Not when Mina just opened the layer again.”
Mina heard none of it clearly for a second because the whole rooftop had turned beautiful and unbearable at once.
She could hear everyone.
Not their words – the feelings underneath them.
Performance anxiety hummed like tight violin strings.
Crushes sparked in pink static.
Loneliness looped in one corner near the vending machines like a song with only one verse.
Confidence strutted.
Envy hissed.
Excitement trembled like cymbals before impact.
How had she never known the world was this loud?
The first-year girls laughed at the phone video again.
One of them deleted a saved song from her favorites.
The Noise seed grew teeth.
Mina moved before thinking.
She crossed half the rooftop in six strides and stopped directly beside the girls’ table.
“You don’t have to follow that account.”
Both girls looked up, startled.
“Sorry?” one said.
Mina, suddenly aware that she had no social plan whatsoever, glanced at the phone screen.
Trend advice reels.
Cleanly branded.
Aggressively sure.
Behind the girls, the little gray thing clung to the speaker grille and grinned.
Mina heard Riot say, from somewhere over her shoulder, “Say what you actually think.”
Terrible advice.
She took it.
“It’s stupid,” Mina said.
The girls blinked.
Mina pointed at the video.
“Not you.
This.
You don’t need some account telling you your taste only counts if it matches a concept board.”
The second girl frowned.
“We were just watching it.”
“Yeah, and it’s already trying to make you smaller.”
Wonderful, Mina thought.
I’ve gone from haunted to incomprehensible in under an hour.
But something happened.
The first girl looked from the screen to Mina’s face and then down at her own playlist, still open beneath the video app.
“I mean,” she said slowly, “their advice is kind of annoying.”
The Noise seed twitched.
Encouraged despite herself, Mina pressed on.
“Then mute it.”
The girl hesitated, then snorted and blocked the account.
The gray thing let out a high, furious squeak only Mina and the A-MUSEs seemed able to hear.
It lost shape at once, teeth blurring, mask-face caving inward.
Flux whooped.
“Yo!
She freestyled a save.”
Bell clapped both hands over her mouth in delight.
Riot looked almost smug, which on him resembled general hostility with better posture.
The second girl laughed.
“Okay, maybe that account is annoying.”
The first girl reopened the deleted track and added it back to favorites.
A warm yellow-pink chord rang through the rooftop.
The last of the gray static blew away in the wind like pencil dust.
The Sound Layer thinned.
Ordinary lunchtime returned.
The girls were still looking at Mina.
“Uh,” said the first one.
“Thanks, I guess?”
Mina nodded once and retreated at a speed just slow enough to preserve dignity.
When she reached Soomin again, her friend stared at her as if a decorative plant had suddenly delivered a political speech.
“You,” Soomin said carefully, “just walked across the rooftop to tell strangers not to let an algorithm parent them.”
Mina sat down.
“Did I?”
“Yes.”
“Interesting.”
“That word is doing no work right now.”
Bell floated invisibly beside Mina’s shoulder, vibrating with excitement.
“You helped!”
“I socially detonated,” Mina hissed under her breath.
Soomin squinted.
“Are you talking to yourself?”
“No.”
“That answer was directed at the air.”
Mina opened her lunch as if this were a decisive argument.
It was not, but it bought her twelve seconds of silence.
Riot sat on the fence post behind her and looked out over the school grounds.
“The layer opened more easily that time.”
Bell nodded.
“And she sensed a seed before it manifested fully.”
Flux leaned upside down in midair.
“Mina Lee, accidental disaster and possible specialist.”
Mina swallowed a mouthful of rice too fast and nearly choked.
Soomin handed her water with the resigned patience of someone accustomed to bizarre behavior from artists.
“You need sleep.”
Mina laughed helplessly because sleep sounded like a childhood rumor.
* * *
By the final period, denial was no longer available as a strategy.
The Sound Layer did not stay wide open, but it flashed through everything now, thin as lightning under skin.
A teacher’s praise left golden echoes in the room.
A harsh joke near the lockers produced gray static that dispersed if ignored and thickened if repeated.
When Mina passed the music practice rooms, she heard not just scales and half-finished songs, but the emotional weather inside them: determination pounding like snare drums, embarrassment folding inward like damp paper, hope hovering in high trembling harmonics.
Every time she noticed, the three A-MUSEs noticed her noticing.
They were becoming unbearable.
Bell cooed over every small emotional recovery like a proud kindergarten teacher.
Flux narrated social dynamics as if casting a reality show.
Riot rejected at least six students on sight for “terrible internal rhythm,” which was not a category Mina had asked to know existed.
And yet, beneath the absurdity, something in her had begun to recalibrate.
The school no longer felt like a flat stage where students performed identity for one another.
It felt layered, fragile, alive.
Everyone carried a song they were trying not to lose.
By homeroom, Mina was exhausted enough to stop fighting that thought.
Rain had ended by dismissal.
The city outside the gates gleamed in wet reflections, traffic lights smearing red and green over the pavement.
Students spilled outward in packs, their after-school plans colliding in overlapping choruses.
Mina adjusted her backpack and headed toward the side street that led to the bus stop.
“You’re quiet,” Bell said gently, floating just above her shoulder now that they were outside school.
“She’s either processing or plotting our murder,” Flux said.
“I vote processing,” Bell replied.
“I vote both,” said Riot.
Mina kept walking.
“Do all of you live in my phone now?”
Bell tilted her head.
“Not exactly.”
“We anchor where your attention and sound are strongest,” Flux said.
“Phone, earbuds, songs you loop until they become architecture in your heart.
Standard stuff.”
“Nothing about that sentence was standard.”
Riot hopped from the top of a mailbox to a street sign without making the metal bend.
“You’ll get used to it.”
“I don’t want to get used to it.”
He gave her a long look.
“That’s not the same thing as not already changing.”
The answer irritated her because it sounded true.
They passed a convenience store.
The automatic doors opened with a bright three-note chime, and Mina saw the sound spread like small yellow tiles across the sidewalk before fading.
An older man inside hummed under his breath while choosing instant noodles.
Near him, for one heartbeat only, a tiny shape flickered in the reflection of the refrigerator glass – small, round, warm-colored, gone the moment Mina tried to focus.
She stopped walking.
Bell followed her gaze.
“You saw that?”
“What was it?”
“Someone’s partner, maybe,” Bell said softly.
“Most stay hidden.
Sometimes the layer gets thin around you and things leak through.”
“Leak through,” Mina repeated.
“Awesome.
Love that.”
Flux pointed across the street.
“Bus stop.”
The city bus shelter glowed damp blue in the early evening.
Three students from another school stood under it sharing earbuds.
A woman in office clothes rubbed her eyes while staring at a grocery bag.
A little kid in a yellow raincoat bounced on the bench and sang to himself off-key with perfect confidence.
Mina slowed.
The child’s tune left bright orange circles in the air.
The office worker’s fatigue sounded like paper rubbed thin.
And from the far end of the shelter, near a boy in dark school uniform with his hood up despite the now-clear sky, came a sound so faint Mina almost thought it was memory.
A broken hum.
One note, repeated.
Soft.
Careful.
Hurt.
Gray static shivered around his shoes.
Bell inhaled sharply.
Flux’s grin vanished.
Riot’s posture changed in an instant, every sharp edge of him focusing.
Mina stopped completely.
“What?”
The boy at the end of the shelter stared at the ground, one earbud in, hands deep in his pockets.
Nothing about him stood out in an ordinary way.
He could have been any tired student on any wet weekday in any city.
Except the sound around him kept trying to disappear.
Bell’s voice was barely above a whisper.
“That’s not a seed.”
Riot’s answer came low and hard.
“No.”
Flux looked at Mina.
“That,” he said, with no humor left at all, “is what happens when Noise gets farther in.”
The bus stop lights flickered.
The boy’s broken hum cut off mid-note.
And from the puddle at his feet, something dark began to rise.
