Obsessive [J.JK FF]

Three years ago, everything fell apart with one reckless mistake.

In high school, Jungkook had it all - the girl everyone admired and the kind of love people only dream about. Y/N wasn't just beautiful; she was unforgettable. Effortlessly kind, fiercely loyal, and stunning in a way that made the world blur around her, she was different from anyone he had ever known. It took Jungkook two long years to earn her heart. Two years of patience, devotion, and proving he was worthy of her.

And one drunken night destroyed it all.

A party. A blurred memory. A betrayal he could never take back.

When Y/N found out, she didn't scream. She didn't beg. She simply walked away. And that silence hurt more than anything else ever could.

Now, three years later, they're no longer teenagers navigating lockers and late-night phone calls. Jungkook is no longer just a boy in love - he's the cold, calculating CEO of Hublot, the luxury watch empire built by his father and handed down to him. Success follows him everywhere. Power bends in his direction. The world sees a disciplined businessman with an unreadable expression and a heart locked behind steel walls.

But behind the tailored suits and boardroom dominance lies a man who never moved on.

While Y/N rebuilt herself, healed, and stepped into a new chapter of her life, Jungkook stayed frozen in the past - haunted by the one person he could never replace. He doesn't date. He doesn't fall. He doesn't even try.

Because no one is her.
And when fate places Y/N back in his orbit.

He lost her once.

He won't make the same mistake again.
