Once My Hyung, Now My Enemy [ Taekook ]

"best friends to enemies to lovers"

Once best friends since childhood but now enemies

Taehyung's voice dripped with mockery and anger as he glared at Jungkook.
"I'll see how long you can keep pretending like nothing hurts," he said coldly. "I'll make sure to strip that confidence off you, Mr. Jeon."

Jungkook's jaw tightened, eyes sharp yet weary.
"Try me, Kim," he shot back, voice low and steady. "You'll only regret it."

Taehyung's lips curled into a bitter laugh.
"I wouldn't regret it, Jeon."
But he did.
He regretted it more than he ever thought possible.

As one day, that same voice echoed in his mind when he found Jungkook sitting on the cold floor - eyes glassy with unshed tears, the bitter scent of alcohol and heartbreak heavy in the air.

"Hyung..." Jungkook whispered, his voice trembling. "Why do you hate me so much? Didn't I meant anything to you back then? Do you even know what I am going through all these years... because of you?"
The single word hyung cut through the silence like a blade.
Taehyung froze - breath caught, heart pounding. It had been so long since Jungkook had called him that. Since laughter had turned to silence, friendship to rivalry, and care to something unspoken but deeply painful.

"Jungkook..." Taehyung said softly, his voice barely steady. "Come back to your senses. You don't even know what you're saying."

He tried to sound detached, but his heart betrayed him - racing, aching, almost relieved to hear that old name fall from Jungkook's lips again.

And in that fragile moment, the walls between them cracked.
The anger and pride melted away, leaving only two broken hearts

Will their unresolved past finally break them apart, or will the tension evolve into something neither expects? The story is a rollercoaster of romantic angst, dark emotions, playful teasing, and intense rivalry, with a slow-burning romance that promises heartache, passion, and ultimate catharsis....
