"there's a very fine line between love and hate." after joining the BAU, Y/N must navigate the complicated feelings she's starting to feel for her difficult co-worker, Spencer Reid. *WARNING that this story does contain a heavy DD/LG (daddy kink) component, so if you aren't into that, DO NOT read.* *contains smut*

They've despised each other since childhood. Arguing all the time and disrupting everything. It is pretty obvious Brianna Rose Williams and Ashton Rowan Webster hate each other. She was always nice to everyone, everyone but him and that's what angered him. Because no one saw her "true evil side" and he wanted to prove that she wasn't the angel everyone saw her as. He was cold and ruthless from the start. Obviously still an angel infront of adults but as she claimed, he was 'the devil in disguise.' They liked riling each other up and found everything to fight about: getting higher grades or just proving how "nice" they really were. Their childish feud started at the age of six but even after ten years, can they learn to get along?
