Jung y/n is seventeen. Bright, bold, and 100% mafia-obsessed. While her friends were crushing on K-pop idols, she was Googling "How to spot a real mafia boss." And guess what? She found one. Kind of. Sort of. Okay, she accidentally bumped into him and then made up a whole relationship in her head. Now meet Jeon Jungkook - cold, dangerous, and absolutely not interested in teen drama. He runs an empire of fear, and the last thing he needs is a girl calling him her husband on social media. But y/n doesn't care. She's got heart, guts, and a dangerous amount of delusion. She saw him once... and something inside her shifted. She claimed him in her heart. She chased him with laughter, love, and a madness he couldn't escape. He wants her gone. She wants him in a aisle in a black tuxedo. Who will win? And slowly, the man who never looked back... started to turn around. Can a girl with dreams melt a heart made of stone? Or will loving a mafia man destroy her world forever?
