RELINE || JJK

In Seoul's underground racing world, one mistake can get you killed.

Jeon Jungkook is the king of REDLINE - the most feared illegal racing crew in the city. Cold, untouchable, and dangerously obsessed with winning, nobody dares challenge him.

Until a mysterious girl appears out of nowhere and humiliates his best racer in front of everyone.

Y/N enters the underground scene hiding secrets powerful enough to destroy lives. She didn't come for money, fame, or thrills.

She came for revenge.

But the deeper she falls into Jungkook's world of luxury cars, violence, betrayal, and late-night races, the harder it becomes to remember why she hated him in the first place.

Because Jungkook isn't just dangerous on the track.

He's dangerous for her heart too.
