Rival Rhythm // Changbin ff

Avery Min‑seo Lark has three rules:
Stay quiet. Stay hidden. Stay alive.
But rules don't mean much when you're born with a last name that every gang in Port Nocturne wants erased. Avery - known on the streets simply as Avery - has spent years outrunning the shadows tied to her family's past. She's fast, smart, and impossible to pin down... until one mistake forces her straight into the territory of the city's most dangerous crew. The Black Harbor. And worse - into the path of their cold‑eyed enforcer, the one man everyone fears and no one crosses. He wasn't supposed to notice her. She wasn't supposed to talk to him. And falling for him? That was never part of the plan. But Avery has always been good at breaking rules... And he's about to become the one person she can't run from. In a city ruled by neon lights, secrets, and rival gangs, Avery must decide:
Will she keep hiding in the dark - or burn the whole city down to protect the people she loves?

Trigger warnings: Blood, violence, smut, cursing.
