12 parts Ongoing MatureWhen Y/N steps into the BAU as the newest recruit, she expects long nights, tough cases, and the pressure of proving herself. What she doesn't expect is Dr. Spencer Reid-the team's resident genius with a razor-sharp memory and an even sharper tongue.
From day one, Spencer makes it clear he doesn't think she belongs. He's snarky, dismissive, and far too good at pointing out her mistakes. To him, she's an unwelcome distraction in a world where there's no room for error. To her, he's insufferable and brilliant, yes, but also infuriating.
But as the cases grow darker and the danger more real, Y/N and Spencer are forced to rely on each other. Between late-night stakeouts, heated arguments, and the quiet moments that slip through the cracks, the line between rivalry and something far more complicated begins to blur.
He's the last person she thought she'd fall for. She's the one person he never saw coming. And sometimes, the hardest mystery to solve is the one written in your own heart.
