The Devil Inside Us. Jungkook x Reader.

Jungkook always thought his biggest battles were with high school bullies-until the day he unleashed something far more dangerous. A fiery rage and icy fear collide within him, leaving destruction in their wake. When his best friend Y/N uncovers their shared connection to these supernatural forces, the two must navigate a world of hidden powers, dark secrets, and a bond forged by destiny.
But controlling these abilities is only the beginning. Haunted by the loss of a brother who may have known the truth all along, Jungkook and Y/N are thrust into a fight for their lives-and their humanity. As the line between good and evil blurs, they'll discover that the devil inside isn't always the one you expect.
Can they master the chaos within, or will it consume them both?
