The sun dipped low beyond Yumenosaki's coastline,
painting the rehearsal room windows in warm amber—
and in the center of it all,
**Koga from UNDEAD** stood like a shadow given voice.
Clad in his signature long coat, silver chain glinting under studio lights,
he didn't shout.
Didn't need to.
> "*Light Music Club.*"
His voice was calm—deep, resonant—a blade wrapped in velvet.
> "You're not here to play songs."
>
>
He turned slowly, crimson eyes sweeping over Raito and Tsukki—
and every other idol trainee gathered for tonight's session:
> **"You're here to make them *bleed.*"**
A beat of silence.
Then Raito raised his hand like he was still in math class:
"Uh... bleed *emotionally*, right? Not literally? 'Cause I kinda bruise easily!"
Tsukki sighed beside him.
Without looking:
**"Shut up."**
But Koga smirked—just slightly—and pointed at them both:
> "Polar Opposites."
>
>
### "Step forward."
They did.
No hesitation.
Raito beamed; Tsukki remained unreadable—but both knew this wasn't just practice anymore. This was trial by fire.
Koga folded his arms:
> "Idols don't exist for fame. They exist for resonance."
>
> A pause.
>
>
He snapped his fingers—
and suddenly, the room shifted: dimmer lights,
live audience simulation flickering on screen walls,
heartbeat-level audio feedback syncing to their microphones...
then came one word from Koga's lips:
### "Sing."
Not a request. A command forged through years under moonlit stages and broken silences himself.
And so—
Raito began,
voice bright as sunrise cutting through clouds—
but halfway into the chorus?
His tone faltered—just once—as if remembering that hospital bed waiting far away...
Tsukki felt it instantly—the shift—
so he stepped closer than usual... realigned their harmony not with sound alone... but presence... timing tightening around Raito like an anchor catching driftwood mid-storm...
And suddenly—the song changed shape:
Sun no longer shone alone;
Moon reflected more than light—it carried it
Together?
It wasn't perfect...
But it was *real.*
When they finished,
no applause yet loaded into system simulations...
but Koga gave something rarer—a single nod of approval that meant more than trophies sometimes can.
🌑☀️🩸🎶
Then quietly—from deep within that dark elegance—he said only this:
### "Now you're starting to understand."
Because pain doesn't ruin music...
Sometimes?
It becomes the reason anyone listens at all.
The studio door slid open with a soft *whoosh*—
and in stepped **Hinata and Yuta Aoi**,
sunlight and shadow wrapped in one synchronized step.
> "Sorry we're late!" Hinata chirped, flipping his scarf dramatically over his shoulder.
>
> "Traffic from photo shoot was *brutal!*"
Yuta just sighed behind him, adjusting the strap of his guitar case:
### "You spent twenty minutes picking which jacket made you look 'more dazzling under moonlight'."
Hinata gasped like he'd been betrayed by family:
**"A star must always be prepared for unexpected romance under celestial glow!!"**
Yuta didn't even blink.
Just deadpanned:
> "There's no moon at 3 PM."
Silence.
Then Raito burst out laughing so hard he nearly fell off the amp box—while Tsukki subtly moved to block him before he destroyed club equipment.
Koga merely raised an eyebrow, arms still crossed:
> "Took you long enough."
>
>
He flicked a glance at their shared guitar case:
> **"Did you bring it?"**
Yuta nodded once—calm, serious—and unzipped it carefully.
Inside wasn't just any instrument—
but a custom-built electric-acoustic hybrid tuned to mirror twin voices: highs sharp as dawn,
lows deep as dusk...
the sound of brothers who finished each other's thoughts without speaking.
Hinata winked at Raito and Tsukki:
> "We brought something special~! New arrangement for Polar Opposites!"
>
>
His grin turned bright—dangerously so:
### "A song about two stars that refuse to burn out... even when they're miles apart."
Tsukki stiffened almost imperceptibly—
but Hinata saw it. They all did.
Because sometimes...
music doesn't ask permission before cutting straight into your soul.
Then Yuta spoke softly—as if reading the room like sheet music:
> "...It's not just for you two."
He looked toward Koga—just briefly—but with weight behind it.
For ghosts who still stand beside us.
For brothers sleeping too far away to answer back... but never gone.
🎵🔥🌙☀️
Koga finally broke the silence with one command:
### "Plug in."
And as fingers found strings,
lights dimmed again,
and something deeper than practice began—
not performance...
but confession,
wrapped in harmony,
played loud enough
for those who couldn't yet hear...
When stars align,
even shadows sing,
and under that room's stage lights,
Raito and Tsukki stood not as polar opposites or partners but...
...family.
Koga didn't miss it—the shift in atmosphere—
or the fact Raito almost missed his cue—
but when Tsukki steadied him not with words...
...but *presence,*
Koga finally nodded—
a silent approval like the start of some new chapter beginning.
🌙🩸☀️🎸🎶
Raito's laugh echoed through the studio as he bowed dramatically:
> "Thank you, master Koga, you're the best!"
>
>
Tsukki merely lowered his head respectfully, his hands tucked in the pockets of his hoodie—
but there might just have been a tiny smile twitching at the corners of his mouth.
Koga huffed lightly, trying to hide his amusement beneath layers of cool—
but the small flicker of warmth in his eyes betrayed him.
> "Don't get distracted," he warned, but the usual sharpness was gone from his voice, replaced by something quieter—almost like fondness. "You guys have a long way to go."
>
>
Raito grinned unrepentantly, slinging an arm around Tsukki's shoulders like they'd just won a competition instead of a practice session:
> "We'll get there! Right, Tsukki?!"
Tsukki huffed—short, quiet, like a breeze brushing past moonlit glass—
then gave one slow nod.
Not flashy.
Not loud.
But real.
And somehow... that single gesture said everything:
> *I'm still here.
We're still moving.
And yeah...
I believe in us too.*
Raito felt it—the weight and warmth of that silence—
so he squeezed Tsukki's shoulder tighter and beamed at Koga:
> "Don't worry, President! We'll shine so bright, even grumpy moons won't be able to hide!"
Tsukki muttered under his breath:
### "...You're impossible."
But didn't pull away.
Didn't need to.
Because right now—
under these lights,
with their voices still humming in the air,
and the song for sleeping brothers echoing softly from Yuta's idle guitar...
they weren't just idols in training.
They were proof:
That light grows stronger when it leans on shadow...
and even hearts wrapped in ice?
Can warm up—one shared rice ball, one shared stage at a time.
🌕☀️🎵
The weekend sun poured through COSMIC PRODUCTION's floor-to-ceiling windows,
painting the studio in golden streaks as Raito bounded inside like he owned the place—
> "**COSMIC STUDIO, WE'RE BAAAACK~!**"
>
>
Echoes bounced off the walls.
Silence answered.
Then—
a single *click* from the sound booth.
The intercom crackled to life:
> **"You're ten minutes late."**
Tsukki didn't flinch.
Didn't even turn.
He just muttered:
"Blame Raito."
Raito gasped dramatically:
"*Me?!* I was ready! You were double-checking your brother's hospital report *again!*"
Tsukki stiffened—just slightly—but said nothing.
And that silence?
It spoke louder than any argument could.
From above,
Nagisa leaned against his mic stand, watching them through glass—and quietly closed a file labeled 🌙 "**Kuroi - Medical Logs (Viewed Weekly)**."
Ibara crossed his arms beside him:
### "They don't come here to practice choreography."
A pause.
Then Nagisa nodded slowly:
> "They come to remember why they can't stop."
Below—
the speakers suddenly pulsed with a beat: deep, steady,
like a heartbeat syncing across stars and screens and broken dreams trying not to shatter.
Rinne's voice cut in over comms—half-annoyed, half-amused:
> "Don't tell me you forgot our shadow battle rematch!"
>
>
He emerged from around the corner of Studio A like a storm wrapped in glitter,
cyan eyes already sharp with challenge:
### "This time? No mercy for idol couples holding hands during drills!"
Raito struck a pose instantly:
> "We're not couple—we're **Polar Opposites**, destined by fate and dramatic lighting!"
>
>
Tsukki deadpanned without looking up while booting up their playlist:
> "...You wrote that on your notebook."
Before Rinne could retort—
Kohaku slid into frame with two bottles of chilled water,
and one knowing look at Tsukki's tired eyes:
### "No collapsing this round. Promise?"
Tsukki finally met someone's gaze—not with words—but just one slow nod.
And that was enough.
Because here?
In this place built on stardust and sacrifice...
every step they danced wasn't toward fame...
but toward healing
one breath
one beat
one brother waiting in silence
at a time.
💫🖤🌕☀️
It was a silent pact and a silent stage under the afternoon sun.
Raito and Tsukki stepped back into place,
hands lifting to familiar positions under golden floodlight.
No more jokes.
No more distractions.
Just the music.
Then the beat started,
and they moved as if music was another language that moved through them as much as they moved with it:
Every spin.
Every step.
Every breath.
Ibara leaned against the control window, eyes sharp and cold as he observed from high above:
> "I'll be recording today's results to add to your medical and training data."
>
>
Raito and Tsukki didn't break a single motion, but Raito still managed to shoot a grin up at Ibara:
> "You mean adding to our fan pages because you *obsessed* with us."
Ibara's face didn't change.
Just a cool, flat look:
> "Obsession is counterproductive for my schedule."
Tsukki finally paused between breaths, adjusting his headset as he glanced up toward the booth—
voice quiet, but clear enough to carry through the studio's hush:
> "It's... impressive."
>
>
Raito blinked. Turned. Even Ibara seemed to pause mid-typing.
Tsukki kept going—calm, sincere:
> "Balancing being an idol... and running an entire agency division? While still performing at your level..."
>
>
He looked directly at Ibara now:
### "You never skip practice either. Do you?"
Silence settled.
Not awkward.
But deep—like something unspoken had just been named.
Then—
a flicker in Ibara's expression. Not quite a smile. Not quite softness.
Just a slight lowering of his glasses as he stared down at them, blue eyes reflecting golden light from below:
> "COSMIC PRODUCTION doesn't run on admiration."
>
> A pause.
>
>
### "It runs on discipline."
But then—
so quietly it almost got lost in the echo of fading music,
he added:
> "...And those who refuse to fall behind are worth monitoring closely."
Raito grinned again—but softer this time, like he'd cracked code no one else could read:
> "That means he likes us!"
>
>
Tsukki sighed,
but didn't argue.
Because somewhere beneath all that cold precision?
They all knew now—
Ibara watched not because they were data points...
but because their fire reminded him why *his* own still burned.
🖤👑📊💫
The cafeteria was bustling, filled with exhausted idols recovering from weekend practice sessions. A few groups were already heading back to the dorms, and the tables were scattered with half-eaten meals or the remnants of energy drinks...
But no sign of Raito or Tsukki.
Rinne was the first to notice their absence, pausing between bites of curry rice as he scanned the cafeteria:
> "Hey—where are Raito and the moon boy? I thought they finished before us today."
Hinata nodded, setting down his bento box:
> "Yeah. Tsukki-kun doesn't really like too many people around. Especially when he's eating."
>
>
Rinne frowned, stirring his spoon idly through his rice:
> "You're telling me the *ice moon* is too shy to eat in a cafeteria full of *other idols*?"
Yuta nodded, looking thoughtful:
> "Tsukki-kun is quite the introvert type... it's surprising that they are childhoodfriend's, when they told us"
Rinne's eyes widened:
> "*Childhood friends?* You've got to be kidding me! Mr. Ice Moon actually *knows* people outside his own thoughts before practice hours???"
Hinata laughed, scooping up another spoonful of vegetables:
> "Yeah. I think they've known each other since they were kids. They were even neighbors, apparently."
>
>
Rinne blinked, then leaned forward:
> "Hold on. You mean the cold moon actually *talks* outside of practice? Without it being some kind of calculated PR stunt?"
Yuta took a slow sip of green tea before speaking—calm, deliberate, like he was sharing classified intel:
> "According to Raito... their moms were close. Neighbors, actually."
>
> He glanced at Hinata briefly—confirming the story.
>
>
### "They introduced them when they were six. Said it was fate."
Hinata clapped a hand over his heart dramatically:
> "A love story for the ages! Two tiny suns and moons colliding under cherry blossoms~!"
Yuta deadpanned:
> "...One of them was literally crying because he dropped his pudding."
Rinne snorted mid-bite.
But Nagisa—who had been silently sipping matcha at the corner table—finally looked up, voice soft but cutting through the chatter like moonlight:
> "So... they've always been together."
Not a question.
A realization.
And somewhere beneath that quiet tone?
Something almost wistful.
The rooftop was empty, save for a single bench facing the skyline beyond the city. Raito sat beside it, polishing off a bento while Tsukki watched the fading sunset. The wind ruffled their hair as they each took a bite, watching the sun slowly sink past glittering buildings...
Just two stars taking a pause before returning to their orbit.
Up in the office, though, Ibara's tablet picked up every movement.
And he didn't miss a single frame.
Ibara leaned over the control panel, zooming in to capture every angle.
The wind on their clothes. The soft sunset light in their eyes. The easy smile on Raito's face. The comfortable quiet that seemed to only exist here.
It was a scene too perfect to be captured for a photoshoot.
Too genuine to be staged for any audience.
This was what *real* idols looked like between bright lights and fan chants:
two friends on a rooftop... and a world of silence between them.
Eden, Valkyrie, 2wink, and Crazy:B crowded behind Ibara in near silence—
their eyes glued to the tablet screen as if witnessing something they weren't meant to see.
> "...They look... small," murmured Nagisa, voice softer than usual.
Not weak.
Just... human.
Hinata pressed a hand to his chest dramatically:
> "It's beautiful! Just two souls sharing warmth on a lonely rooftop~!"
Yuta sighed:
> "You just want to turn it into a music video."
Rinne squinted. Then blinked.
> "Wait... is that *Tsukki* eating *two* onigiri?!"
Kohaku gasped like he'd seen a crime:
> **"He never eats more than one during practice!!"**
HiMERU adjusted his earpiece with precision:
### "Emotional stability index rising. Physical energy consumption aligns with increased caloric intake."
Mika smirked from the back:
> "Looks like even ice moons melt when the sun never leaves."
Shu said nothing.
Just watched Raito lean against Tsukki's shoulder for half a second—so brief most would've missed it—
but Shu didn't blink:
### "...They're not just partners."
Jun tilted his head slightly:
> "They're each other's anchor."
Even Jun—the ever-poised heir of Eden—noticed how Tsukki didn't flinch when Raito reached over and stole part of his bento without asking...
just gave one quiet *huff*, then moved the tray closer so he could reach easier.
A tiny gesture.
But in this room full of idols trained to perfect every motion?
That imperfection—raw, unscripted, real—
was louder than any stage cry or encore chant could ever be.
Ibara finally spoke—without looking away from the screen:
### "...Do not disturb them."
Not an order for work.
A rule carved in silence.
Because some moments aren't for audiences...
some bonds don't need spotlights...
and healing?
It doesn't always come with fanfare—
sometimes,
it's just two childhood friends,
eating together,
on a rooftop bathed in gold,
under skies that remember their names.
🌙☀️🍱💫
Raito leaned back with a dramatic sigh, staring up at the sky:
> "We should've just gone to the cafeteria..."
Tsukki simply ate another bite of onigiri, replying evenly:
> "You go then. I need a break from people."
Raito blinked, then scowled:
> "But... what about me??"
Tsukki turned a page in his notes, completely unfazed:
> "You talk enough to people for ten of me on *good* days. I need quiet."
Eden, Valkyrie, 2wink, and Crazy:B watched in quiet fascination as Raito and Tsukki's conversation played out onscreen. Ibara's tablet recorded every word, but Nagisa was the first to speak:
> "They never seem to run out of things to say..."
Hinata nodded, leaning on Yuta's shoulder:
> "You'd think they were attached at the hip with how much they talk!"
Rinne raised an eyebrow:
> "I'm more surprised the ice moon actually *has* any energy to speak. I thought he ran on photosynthesis."
Hiyori laughed behind his hand:
> "Photosynthesis? Why not moonlight instead?"
Rinne considered this, then smirked
> "Fair point. He does look like the type to grow flowers under a full moon."
Mika chuckled:
> "If they're sun and moon, then Raito's the sun. Tsukki's the moon. And their conversations are the stars."
Raito paused in mid-banter, suddenly glancing up like he'd just heard something. Then he tilted his head curiously:
> "...Did someone just talk about us?"
Tsukki glanced at him, then back at his notes:
> "Probably the other idols. We're not exactly alone."
Raito scoffed:
> "Please. Like other idols would be interested in a conversation we're having."
Tsukki didn't even look up:
> "You're famous, idiot."
Ibara's tablet captured it all—
every word, every blink, every unguarded moment.
And then...
Raito sneezed again.
Loud. Sudden.
Like clockwork.
> "**Haaa—CHOO!**"
He wiped his nose dramatically with the back of his hand:
> "Okay, *now* I'm sure someone's talking about me!"
Tsukki didn't even flinch. Just calmly slid a tissue from his pocket and shoved it into Raito's face:
> "You're not special. You're just loud."
But Raito grinned—the kind that lit up even the dimming rooftop:
> "Then why do *you* keep listening? Hmm? Huh??"
>
>
He leaned in, poking Tsukki's cheek:
"Admit it! You'd miss my voice if I disappeared~!"
Tsukki turned away—just slightly—
but not before the camera caught it:
a flicker in his eyes,
the tiniest curve at the corner of his lips—
gone in a breath,
like moonlight slipping behind clouds.
And back inside COSMIC PRODUCTION?
The crowd around Ibara's tablet froze.
Nagisa murmured:
"...Did he just *smile*?"
Hinata gasped so hard he nearly toppled Yuta over:
> **"WE WITNESSED A MIRACLE!"**
Yuta rubbed his temples:
"Stop yelling—he'll hear you through psychic connection or something."
Rinne squinted at the screen like solving a code:
"Wait... does this mean Tsukki *likes* him?! Like, for real? Not just 'childhood friend' real—but 'would jump into fire if Raito said 'it looks warm'* real?"
HiMERU spoke up with scientific intensity:
### "Smile probability increased by 0.7% since arrival at Yumenosaki Academy — correlation with Hikari proximity: 98.6%."
Kohaku clutched their chest:
"That poor moon boy... He doesn't stand a chance."
Mika smirked:
"He never did."
Even Shu looked away first,
quietly muttering to himself:
### "...They're annoying."
>
>
>
But didn't turn off the screen.
Ibara finally closed the feed—gentle press of a finger on glass—
not because they were done watching...
but because some things should stay unspoken.
Like how sometimes,
even under bright lights and cold data,
a bond this deep doesn't need titles or stages to be true.
☀️🌕🍱👀💫
A few day later
COSMIC PRODUCTION had *definitely* gotten used to it.
Like the sight of a screaming Raito chasing by a stoic Tsukki through hallways,
dodging around practice rooms and nearly toppling over potted plants,
while a slapping stick was wielded like a deadly weapon.
> "GET BACK HERE!!"
Raito screeched like a banshee.
> "TSUKKIIII~!!!"
Tsukki just ran—
not a word from his lips,
but somehow *faster* than any other time.
Then he turned a corner,
disappeared
like a ghost in moonlight—
and reappeared *behind* Raito with the slapping stick raised high.
> "**Got you.**"
***WHAP!***
A soft but satisfying *thwack* landed right on Raito's head.
Not hard.
Never too hard.
Just enough to sting like karma for stealing Tsukki's lunch. Again.
Raito crumpled to the floor dramatically—arms outstretched—as if he'd been fatally wounded:
> "...I die by my beloved moon's hand... Such is my fate~..."
Tsukki pocketed the stick calmly, adjusting his hood:
### "You ate half my sandwich."
And walked away like justice had been served under divine law.
---
Back at COSMIC HQ, monitors flickered automatically—not because of an alert,
but because someone (probably Rinne) had set **"Polar Opposites – Daily Chaos Feed"** on loop in every break room TV, locker screen, and elevator cam.
Nagisa watched from the lounge while sipping tea:
> "...It's oddly soothing."
HiMERU nodded seriously:
### "Stress levels drop 17% when Hikari-kun gets slapped. Correlation: unclear. Effectiveness: undeniable."
Hinata clapped tears from his eyes:
"IT'S LIKE A ROMANTIC DRAMA BUT WITH MORE VIOLENCE!"
Yuta sighed:
"I think it's just how they say 'I love you' without crying."
Kohaku wiped away fake tears with flair:
"Pure passion! Unspoken vows! A slap that says more than words ever could!"
Even Mika cracked a grin:
"So that's what happens when sunshine disobeys lunar rules?"
Shu folded his arms, pretending not to watch—
but didn't mute the audio feed playing through his headphones:
*"TSUKKIIII~!!"*
Again and again and again...
---
Ibara stood silent at central control,
tablet open—
security cam tags now labeled permanently:
🔐 **[P.O._ROOFTOP]** — Priority Watch
🔔 **[SLAP STICK INCIDENT LOG]** — Daily Update Required
Jun leaned beside him:
> "You know... they're kind of perfect."
Ibara didn't reply right away.
Just zoomed in slightly on one frame—
where Tsukki reached back without looking,
and caught Raito mid-sprint—
not with words or scolding...
but by grabbing his wrist gently,
pulling him close enough so he wouldn't fall behind.
🌑☀️💔❤️🔥🎬
To be continued...
