President of the fan club

Summary:

When Jungkook’s cousin takes him to an underground rap battle in Seoul, he isn't expecting to have his life changed. But then he sees him: Rap Monster, a rapper so captivating and handsome that Jungkook can’t look away. It’s a fleeting moment, a memory he cherishes.

Years later, Jungkook is just an ordinary guy who posts covers on SoundCloud—never showing his face, just sharing his soulful, honey-like voice.

Then, his phone buzzes.

Kim Namjoon. Rap Monster. In his DMs.

The idol wants him to feature on a track. Jungkook is floored. What he doesn’t know is that Namjoon has been searching for the voice behind the music for months. Enraptured by its sweet, emotive quality, Namjoon is determined to collaborate with the mystery singer.

Now, two worlds are about to collide: the fan who’s been enchanted since day one, and the idol who fell in love with a voice without ever seeing a face.

Chapter Text

The winter of 2010 descended on Seoul like a held breath.

By December, the city had surrendered to cold so bitter it seeped through walls and settled in bones. Street vendors packed up early. Lovers walked closer together, their breath materializing in small clouds before vanishing into the night. The Han River moved dark and slow beneath bridges strung with fairy lights, and somewhere in the district of Hongdae, a steel door with a single red light above it marked the entrance to a world most people didn't know existed.

The Hole.

On Friday nights, the club transformed. By day, it was nothing—a forgotten space between a closed fish market and a convenience store. But when darkness fell and the neon lights flickered on, it became something else entirely. A cathedral for the unsanctioned. A battlefield for those who fought with words instead of weapons.

Tonight, the stakes were higher than they'd ever been.

 

Kim Namjoon walked through the cold with his hands shoved deep into the pockets of his black padded vest. His breath came in white puffs, visible for a moment before dissolving into the night. He told himself the tremor in his fingers was from the temperature. -3°C. Bitter enough to excuse any shake.

But he knew better.

He'd been doing this long enough to recognize the difference between shivering and the thing that coiled in his stomach like a living creature before every performance. Fear was familiar. Fear was an old friend. They had an understanding—it showed up, he acknowledged it, and then he stepped on stage and made it work for him.

This was something else.

This was the weight of everything he'd been working toward for two years, condensed into a single night.

*Bang Si-hyuk is in the audience.*

The thought circled through his head like a mantra. Bang PD. Founder of Big Hit Entertainment. The man who could change everything with a single signature. Sleepy had brought him. Sleepy had seen Namjoon battle last week and had been impressed enough to bring the founder of a major entertainment company to watch him tonight.

Namjoon rounded the corner, and there it was: The Hole. Unremarkable steel door, a single red light above it, the muffled thump of bass bleeding through concrete walls. He'd walked through that door a hundred times. It had never felt like this before.

He caught his reflection in a frosted window as he passed. Baggy black jeans. White Jordans. White snapback worn backwards. White sweater beneath his black padded vest. He'd dressed carefully this morning, before the nerves started, before the weight settled in his chest. Casual enough to look like he belonged. Sharp enough to stand out.

*You're Rap Monster*, he told himself. *You've never lost to anyone. You're not about to start now.*

But B-Free wasn't just anyone.

B-Free was a problem Namjoon had been waiting to solve for months.

He'd watched him battle before. Watched him tear into opponents with insults instead of lyrics, with cruelty instead of craft. The man had talent—you don't survive in the underground without it—but he rarely bothered to use it. Why would he, when being loud and vicious was enough to win? He was a bully with weak raps and a drug problem, his head bigger than an elephant's, strutting around like he was the best rapper to ever live when he was just crude and abrasive, with no talent behind all the noise.

Namjoon had been waiting to dish out this beating for a long time.

He pushed open the door.

 

The heat hit him like a wall. Two hundred bodies in a space meant for half that, all of them moving, all of them vibrating with that particular energy that only exists in rooms like this one. Purple and blue neon painted the crowd in waves, catching on jewelry and sweat and the whites of eyes gone wide with excitement. The bass lived in his teeth. Drunk and rowdy crowds hollered and cheered.

On the stage at the far end of the room, two figures circled each other.

Namjoon stopped breathing.

Tiger JK and Tablo. His hyungs. The men who'd seen a scrawny teenager show up at his first cypher two years ago and had somehow recognized something worth nurturing. They'd taken him under their wings without hesitation, taught him everything they knew, and showed up to every battle he'd ever fought.

And now they were on stage, going head to head. They were pretty even when it came to skill and talent, but Tablo looked like he was winning tonight.

Namjoon felt his face split into a grin before he could stop it. Tablo's third verse landed like a bomb, and the crowd's roar shook the room. Tiger JK laughed and surrendered and pulled his friend into a back-slapping hug.

The chant rose and fell. Namjoon was still grinning when they spotted him.

"There he is!"

Tablo bounded off the stage, Tiger JK right behind him, and suddenly Namjoon was wrapped in two pairs of arms, surrounded by the familiar scents of their colognes and the warmth of their approval. For a moment, the weight in his chest lifted.

"You see that?" Tiger JK was laughing, eyes bright. "You see what I let him do to me up there?"

"You let nothing." Tablo's grin was insufferable. "I earned that victory fair and square."

"Earned it. Sure. Keep telling yourself that."

Namjoon laughed, and it felt like the first real breath he'd taken all night. "You both looked amazing. Tablo hyung, that third verse—"

"I know." Tablo preened. "It was pretty good, wasn't it?"

Tiger JK's hand landed on Namjoon's shoulder, and his expression shifted. The laughter faded, replaced by something heavier. More serious.

"You ready, little brother?"

Namjoon's heart stuttered. He kept his face calm.

"Born ready. I can't wait to dish out lashings to that asshole."

Tiger JK laughed. "I know you are about to drop an atomic bomb on his ass." He clapped Namjoon on the shoulder. "Let me buy you a drink, lil bro. To celebrate the win you're going to get tonight."

They settled onto barstools. Tiger JK signaled the bartender, then leaned in closer.

"He's not alone tonight." His voice was quiet. "Sleepy brought company. Rumor has it he's looking for new talent to sign. You need to bring your A-game tonight."

Namjoon met his gaze steadily. "I got this, big bro. Don't worry. This is gonna be light work for me."

They clinked glasses. For a moment, Namjoon let himself believe it. Let himself imagine what it would feel like to sign a contract. To have real producers behind him. To take his music beyond these cramped stages and into the world.

Then the MC's voice cut through everything.

"Up next, we have a long-awaited battle. The bets are high—I know I already submitted my bet." He worked the crowd like a preacher at a revival. "Let the best man win. Introducing—B-FREE, who has won several battles and calls himself the best rapper..."

Boos and cheers in equal measure. B-Free emerged from the right side of the stage, arms spread wide, that familiar smirk plastered across his face. All black clothes. Gold chains at his throat. Hype men flanking him like ill-fitting armor.

"...and RAP MONSTER, who has won several battles despite being new to the underground scene here. Make some noise!"

The crowd erupted.

Namjoon felt it like a physical force. The wave of sound pushed him forward as he made his way through the parting crowd. He climbed the stage from the left, eyes fixed on his opponent, letting the noise wash over him and settle into his bones.

B-Free's smirk widened as they approached the center of the stage.

*I can't wait to slap that stupid smirk off his lips*, Namjoon thought.

The MC flipped the coin. It spun through the air. Caught the neon light. Landed on the stage floor.

Heads.

B-Free would go first.

*Good*, Namjoon thought. *This gives me an advantage.*

He clapped his hands together. *It's show time.*

 

Thirty minutes.

Five grueling rounds.

Namjoon destroyed him.

Round one, B-Free came out swinging with personal insults. Namjoon's weight. His age. His "pretentious" lyrics about feelings and philosophy. The crowd ate it up, because crowds always do, because insults are easy and require nothing but cruelty.

Then Namjoon stepped to the mic.

And he rapped.

Not just insults—though those came too, sharp and precise and cutting deeper than anything B-Free had managed. But beneath the insults, there was something else. Verses about growing up poor in Ilsan. About his parents' divorce. About the weight of expectation and the terror of failure and the desperate, burning need to be more than what everyone expected.

He rapped about hip-hop as salvation. About words as weapons and shields and bridges all at once. About the boy he used to be, the man he was becoming, the artist he was desperate to be.

By the third round, B-Free's smirk had faded.

By the fourth, his hype men had stopped cheering.

By the fifth, the crowd was hanging on Namjoon's every word like gospel.

When the MC grabbed his wrist and raised it in victory, the roar was deafening. Namjoon let it wash over him. Let the sound fill every empty space inside. Let himself feel the weight of what he'd just done.

Two million won.

A legendary victory.

And somewhere in the crowd, Bang PD was watching.

Namjoon dropped the mic. It hit the stage with a thump that echoed through the speakers. He looked at B-Free one last time—at the red-faced, tight-jawed, utterly defeated expression on the face of a man who had never lost before tonight. His face was as red as a tomato. He wasn't smirking now.

Namjoon let the smirk spread slowly across his face.

B-Free and his crew stomped off stage. Disappeared into the crowd. Namjoon watched them go, felt his chest puff up with something that might have been pride or might have been relief.

*Yeah*, he thought. *I served him cooked tonight.*

The MC grabbed his hand and pulled him into a shoulder hug. "Make some noise for Rap Monster, who just killed B-free! He's walking away with 2 million won tonight. Big-ups, bro!"

The crowd obliged.

 

Descending from the stage felt like stepping out of a dream. The noise faded slightly. The lights seemed less bright. His heartbeat began to slow from its battle-rush to something approaching normal.

Sleepy was waiting at the base of the stage. Bang PD beside him.

"Holy shit, kid." Sleepy's grin was wide and genuine. "I've seen a lot of battles, but that? That was something else."

Namjoon ducked his head, suddenly feeling shy. "Thank you, sunbaenim."

Bang PD extended his hand. Namjoon took it. Firm grip. Assessing gaze. He met it without flinching.

"You crushed it," Bang PD said simply. "Great work. I'd love to talk about how my company can help take your career to the next level."

Namjoon's heart sang.

"I'd like that," he managed. "Thank you, sir."

Sleepy shook his hand too and clapped his shoulder with genuine warmth. "Well deserved, kid. Well deserved."

They exchanged a few more words—logistics, contact information, a meeting scheduled for next week—and then they were gone. Swallowed by the crowd. Leaving Namjoon standing alone at the edge of the dance floor, with his heart trying to beat its way out of his chest.

*I did it.*

*I actually did it.*

He started toward the bar. Toward his hyungs who were already on their feet, already clapping, already beaming with pride—

And then he smelled it.

*Deep Sea Water & Ambergris.*

The scent hit him like a physical blow. Cold, immense, and unknowable. The initial hit was crisp, almost metallic—sea salt and ozone, bright and electric. But beneath that, giving way to something profound: a deep, animalic warmth from ambergris. Salty, marine, slightly sweet. And underneath it all, a hint of smooth, dark driftwood.

It felt ancient. Full of secrets.

It was the most intoxicating thing he'd ever smelled.

*Omega*, his brain supplied before he could stop it. *He smells like—*

*Mine.*

"Hey."

The voice behind him was soft. Uncertain. It didn't belong in this club full of drunk strangers and loud music, and yet somehow it cut through everything else like a blade through fog.

Namjoon turned.

And forgot how to breathe.

The boy standing before him couldn't have been more than seventeen. He was drowning in a black hoodie that swallowed his frame—sleeves past his wrists, hem nearly to his knees. Black jeans. Combat boots with metal spikes that caught the neon light. His hair was pulled back in a messy bun, dark curls escaping to frame his face.

His eyes were enormous. Dark brown and liquid and bright with something Namjoon couldn't name. His nose was small and perfect. His lips slightly parted. Two piercings glinting on his lobe.

He was beautiful.

He was the most beautiful thing Namjoon had ever seen. He looked like an angel—innocent and sexy all at once, and Namjoon's brain short-circuited trying to reconcile the contradiction.

*I swear I'm dreaming*, he thought. *How can someone look so innocent and so—*

"I—" His voice came out rough. He cleared his throat. Tried again. "Hi."

The boy's lips curved into a timid smile. "You were amazing up there." Soft voice. Slight lisp. Something in Namjoon's chest tightened. "Can you please sign my shirt?"

Namjoon blinked. Laughed a little, disbelievingly. "I'm not that famous. Why do you want my autograph?"

The boy's smile widened. Just slightly. "With talent like yours, you'll be famous in no time. I can feel it in my gut."

He reached for his backpack—the biggest backpack Namjoon had ever seen, bulky and covered in pins and patches, ridiculously oversized and somehow endearing on this boy. It looked ridiculously cute. Just like him.

He rummaged for a moment. Produced a black marker. Held it out with slightly trembling fingers.

Namjoon took it. Their fingers brushed. The boy's skin was cold.

"Where should I sign?"

The boy touched his chest. Right over his heart. "Here."

Namjoon's throat went dry.

He stepped closer. Close enough to smell that ocean-and-secrets scent more clearly. Close enough to see the way the boy's lashes cast shadows on his cheeks. He uncapped the marker. Pressed it to the soft fabric of the hoodie. Signed his name in careful block letters directly over the boy's heart.

RAP MONSTER.

For a moment, his hand lingered there. He could feel the warmth of the boy's body through the fabric. Could feel the rapid flutter of his heartbeat against his palm.

*For some reason*, he thought, *I want to imprint myself on his heart.*

He stepped back. Capped the marker. Handed it over.

The boy clutched it like it was precious. His eyes were shining. Beautiful, big, brown, and sweetly innocent.

"Thank you," he whispered.

"Thank *you*." Namjoon wanted to say more. Wanted to ask his name. His age. His phone number. Everything about him. Wanted to wrap him in something warm and take him somewhere quiet and learn every secret hidden behind those enormous eyes.

"NAMJOON!"

Tablo's voice cut through the moment like a blade. Namjoon glanced back automatically. Saw his hyung waving from the bar. Tiger JK grinning beside him.

"Coming!" he called back. He turned to the boy—

But the boy was gone.

Vanished into the crowd as if he'd never existed at all. Namjoon's eyes scanned desperately through the press of bodies. Looking for that oversized hoodie. That dark hair. Anything—

Nothing.

He was gone.

*Shit*, Namjoon thought. *I really don't want to leave this beautiful angel without asking for his number. I have to see him again.*

He turned back, scanned again—but the boy had vanished.

Namjoon stood frozen for a long moment. The phantom scent of Deep Sea Water & Ambergris still lingered in his nose. The ghost of a rapid heartbeat was still warm against his palm.

*Shit.*

"Namjoon!" Tablo again. Insistent.

He shook himself. Forced his feet to move toward the bar.

 

Hours later, after getting trashed with his hyungs at the bar, after walking through the crowd twice trying to find that boy, after going outside into the cold to scan the streets—nothing—Namjoon stumbled out of The Hole with Tiger JK's arm around his shoulders.

Victory was still warm in his chest. The meeting with Bang PD was scheduled. His dreams were about to become a reality.

But as he stood on the frozen sidewalk, pressing his hand to his own chest, right where his heart was, he remembered the warmth of a stranger's heartbeat beneath his palm.

*I hope I see you again*, he thought.

*He was an omega. He smelled so good.*

*He smelled like mine.*

He didn't know it yet, but that hope would follow him for years. Through his trainee days. Through his debut. Through the chaos of rising fame and the loneliness of hotel rooms in foreign cities. It would follow him like a half-remembered song, like a scent on the wind, like a ghost he could never quite catch.

And one day, years later, when he least expected it—

That ghost would walk back into his life.
