Park Jimin - 25

Jimin is the younger twin by only three minutes. Most people can’t tell the difference between the two brothers, but those who know them well understand that while they share the same face, their souls burn in different ways. Jimin grew up in Busan alongside his twin brother, spending countless hours in small gyms, learning how to fight, how to endure pain, and how to stand up again no matter how hard the fall was. While his brother chased the spotlight in the boxing world, Jimin chose to stay behind in Busan to help their parents run the family restaurant. To others, he seems calm and gentle. Quiet. Someone who would rather watch than speak. But in the ring, Jimin fights like fire. His movements are fast, sharp, and explosive, striking suddenly like a spark that turns into an unstoppable blaze. He relies on instinct, emotion, and fierce determination. Despite their different paths, Jimin has never stopped training. Because to him, his twin brother isn’t just family. He is his other half. And if anything ever threatened that bond, Jimin knows exactly what he would do. He would protect his brother no matter the cost. Even if it meant setting the entire world on fire.

Park Jiwon - 25

Jiwon is the older twin by three minutes, though he often jokes that those three minutes make him wiser. Confident, charismatic, and fearless, Jiwon quickly rose through the boxing world after leaving Busan for Seoul, chasing bigger opportunities and tougher opponents. Where Jimin burns like fire, Jiwon moves like a storm. Powerful, relentless, and overwhelming, his fighting style is built on calculated pressure. He studies opponents carefully before striking with unstoppable force, breaking through their defenses like thunder tearing through the sky. In the ring, he’s known for his strength and control. Outside of it, he’s known for his loyalty. Because Jiwon knows something most people don’t understand. No one in the world knows him better than Jimin. Not his coaches. Not his fans. Not even his closest friends. To Jiwon, Jimin is also his other half. And if anything ever happened to his brother, Jiwon wouldn’t hesitate. He would risk everything. His career. His reputation. Even himself. Because the two of them have always lived by the same silent promise: If anyone ever tries to hurt them… Or their family… They will destroy them. Together.

Jeon Jungkook - 27

Jungkook is one of the most respected fighters in Seoul’s boxing scene. Strong, disciplined, and incredibly perceptive, he built a reputation not only for his physical strength but also for his sharp instincts in the ring. Jungkook doesn’t just fight—he reads people. He trained alongside Jiwon for years, the two constantly pushing each other to their limits. Their sparring matches were intense, competitive, and sometimes brutal, but they shared a mutual respect that few fighters ever find. But somewhere along the way, Jungkook’s feelings for Jiwon became more complicated than simple rivalry. What started as admiration slowly turned into something deeper. Something he never openly admitted. Even to himself. Jiwon was fearless, brilliant, impossible to ignore. And Jungkook couldn’t help but watch him more closely than anyone else. Which means if something about Jiwon ever changes… Jungkook might be the first person to notice.

Coach Kang - 48

Coach Kang was the one who first noticed the twins’ potential when they were still teenagers training in a small, worn-down gym in Busan. Most people saw two boys who looked the same. Coach Kang saw something completely different. He saw talent. From the moment he watched them spar, he knew they weren’t ordinary fighters. There was something rare in the way they moved, the way they reacted to each other’s attacks, and the way they refused to back down no matter how hard the fight became. Coach Kang decided then that he would train them. Not just as students, but as fighters who deserved the chance to reach their dreams. Over the years, he came to understand something no one else truly noticed. Even though they shared the same face, the twins fought in completely different ways. Jiwon fought like a storm—powerful, controlled, overwhelming. Jimin fought like fire—sharp, explosive, and unpredictable. And when the two of them trained together… They became something far more dangerous. Because in all his years as a coach, Coach Kang had never seen anything like it before. Two fighters who moved like fire and storm. Separate, they were already strong. But together… They were unstoppable.

A few years ago

———

The old boxing gym in Busan always smelled the same.

Sweat. Leather. Dust.

The heavy bags creaked with every hit, chains rattling against the ceiling while gloves slammed into worn surfaces again and again.

Outside the open windows, the distant sound of waves mixed with the rhythm of fists meeting leather.

Inside the ring stood two young men who looked almost identical.

Same height.
Same sharp eyes.
Same dark hair falling slightly over their foreheads.

Twins.

But the way they fought was nothing alike. Jiwon moved first.

His footwork was explosive as he rushed forward, throwing a rapid combination that forced his opponent back against the ropes.

His punches came like a barrage—fast, relentless, overwhelming.

Across from him, Jimin raised his guard calmly. Instead of rushing back, he watched. Waited.

Then—

A sharp step. A precise counter.

His fist slipped through Jiwon’s defense and tapped his chin.

Jiwon stumbled back and groaned.

Outside the ring, Coach Kang crossed his arms.

Both twins lowered their gloves, breathing heavily.

Jiwon wiped sweat from his forehead and smirked.

Jimin chuckled quietly.

Coach Kang stepped closer to the ring, studying them both with experienced eyes.

Jiwon grinned immediately.

Coach Kang shook his head.

He walked toward the ring and leaned on the ropes.

Jiwon raised an eyebrow.

Coach Kang nodded.

Jiwon chuckled proudly.

Coach Kang then looked at Jimin.

He paused.

Jimin tilted his head slightly.

Coach Kang gestured slowly with his hand.

He snapped his fingers.

Jiwon laughed loudly.

Coach Kang immediately shook his head.

He pointed directly at Jimin.

Jiwon blinked.

Coach Kang continued.

For a moment, the gym fell quiet.

Jimin lowered his gloves slightly, thoughtful. Jiwon stared at his twin… then suddenly grinned again.

He bumped his glove against Jimin’s shoulder.

Coach Kang sighed but smiled.

———

Present day.

———

The kitchen of the Park family restaurant was loud.

Oil crackled in pans. Plates clattered. Customers chatted loudly in the small dining room outside.

Jimin moved between tables with practiced ease, placing dishes down carefully.

Customer: Thank you!

He bowed politely before heading back toward the kitchen, Unlike the gym, this place smelled like garlic, chili, and grilled fish.

His parents had owned the restaurant in Busan for decades.

Jiwon had left years ago for bigger opportunities in Seoul, But Jimin had stayed.

Not because he couldn’t leave, but because someone had to stay.

Still… every morning before work, Jimin trained.

Heavy bags in a small local gym, running by the harbor, shadowboxing alone in the quiet dawn.

Fire never stopped burning.

His phone buzzed in his pocket. Jimin wiped his hands on a towel and checked the screen.

Coach kang 📲

The message was short.

Too short.

His chest tightened instantly.

Another message followed.

Jimin’s stomach dropped, his fingers trembled as he opened the last message.

The kitchen noise suddenly felt distant, like the world had been pushed underwater.

Someone called from the dining room.

But he couldn’t move, his hands slowly lowered.

Jiwon was stronger than anyone. Faster, Unstoppable.

Storms didn’t just… disappear.

His phone buzzed again, another message.

Jimin’s eyes sharpened instantly.

Then one final line.

Silence filled Jimin’s mind.

Slowly… something else began to grow.

Not grief.

Not yet.

Anger.

Hot.

Steady.

Burning

Fire 🔥

Jimin whispered to himself.

Images flashed through his mind.

Jiwon laughing in the gym, teasing him after sparring, leaving for Seoul with a confident grin.

Jimin clenched his fists.

If Jiwon’s death was really an accident…

Then fine.

But if it wasn’t—

Jimin’s eyes darkened, a thought formed slowly.

Dangerous, Crazy, But possible.

Jimin whispered.

Same height, face, voice.

Identical twins.

In the boxing world… Jiwon was already known.

Feared.

Respected.

Jimin looked at his reflection in the small kitchen window.

For a moment… he almost saw his brother staring back.

Jimin exhaled slowly.

His eyes hardened.

Even if he had to step into the ring himself.

Even if he had to become someone else.

Storm might have disappeared.

But fire…

Fire was just getting started.

The night air in Seoul was colder than Jimin remembered.

The city lights stretched endlessly across the skyline, glowing like stars trapped between glass towers. Cars rushed along the streets below while crowds moved through sidewalks without slowing down.

Two weeks.

Two weeks since the message that shattered everything.

Jimin stood in the shadows outside an old boxing gym, the hood of his jacket pulled low.

The sign above the entrance flickered slightly in the dark.

This was where Jiwon had trained, where his life had changed.

Jimin exhaled slowly before pushing the door open.

The familiar smell of sweat and leather hit him instantly. Inside, the gym was almost empty. Only a few lights were on, casting long shadows across the floor.

Near the ring stood a man with his arms crossed.

Coach Kang.

He looked older than Jimin remembered. Dark circles sat under his eyes like he hadn’t slept properly in weeks.

Coach Kang turned when he heard the door.

For a moment he just stared.

Jimin stepped forward quietly.

Silence settled between them.

Coach Kang’s expression slowly shifted from surprise to something heavier.

Guilt.

Jimin shook his head immediately.

His voice was steady.

Coach Kang’s jaw tightened.

Jimin’s eyes hardened.

Coach Kang didn’t answer, that silence was answer enough.

Jimin stepped closer.

Coach Kang frowned slightly.

Jimin looked around the empty gym before speaking again.

Coach Kang immediately looked suspicious.

Jimin met his gaze.

The words hung in the air. Coach Kang blinked, then blinked again.

Jimin’s expression didn’t change.

Coach Kang rubbed his face slowly like he was trying to wake himself up.

Jimin crossed his arms.

Coach Kang shook his head.

He walked toward the ring slowly.

Coach Kang looked at him sharply.

Jimin stepped closer to the ring.

Coach Kang listened carefully.

Jimin continued.

Coach Kang slowly understood.

Coach Kang stared at him.

Jimin didn’t hesitate.

The determination in his voice made the room feel heavier. Coach Kang studied him for a long moment.

Jimin’s eyes didn’t waver.

His fists clenched slowly.

Coach Kang looked away for a moment.

Jimin’s voice lowered.

The gym was silent except for the faint hum of the lights.

Finally, Coach Kang sighed deeply.

Jimin didn’t reply.

Coach Kang looked back at him.

Jimin blinked.

Coach Kang raised a finger.

Coach Kang grabbed his jacket.

———

Twenty minutes later they stood in front of a modern apartment building in Seoul.

Coach Kang pulled out a key.

Jimin felt a strange tightness in his chest as they walked inside. The apartment still looked lived in.

Boxing gloves rested on the table, training shoes near the door, photos from fights pinned to the wall.

It felt like Jiwon could walk in any second.

Jimin looked at one of the photos.

Jiwon stood in the ring, sweaty and smiling proudly.

Coach Kang watched him quietly.

He tossed a pair of boxing gloves toward Jimin.

Jimin caught them.

Jimin glanced down at the gloves.

Jimin tightened the gloves around his hands.

Jimin gave a small smile.

Coach Kang sighed.

Jimin raised an eyebrow.

Jimin paused.

Coach Kang crossed his arms.

Jimin felt something uneasy twist in his stomach.

Because he knows who he is talking about.

Jimin spoke quietly.

What Jimin didn’t know…

Was that Jungkook had already spent the last two weeks questioning everything about the fight.

And if anyone could notice the difference between a storm and a fire—

It would be him.
