"I hated you from the moment I met you. But I've loved you for what feels like lifetimes longer." Kaia Claire was never even supposed to go to Hogwarts. She was never supposed to date her best friend. Especially considering this, she was never supposed to fall for the one boy that should be her enemy. Much less, he wasn't supposed to fall for her. Kaia couldn't wait to start her 4th year at Hogwarts, the school she called home. It was an escape from her parents, a place to see all her best friends, the marauders, and where she could do what she loved; magic. Things become complicated when she begins a fake relationship with Sirius Black and constantly encounters his estranged brother all of the sudden with whom she's had a mutual hatred for years. But what if there's more to Regulus Black than meets the eye? The last thing Kaia needs is a distraction or to hurt her best friend. And the last thing she wants is Regulus Black, the Slytherin who wants to ruin her life. **All character/setting rights to J.K. Rowling except for the Claires
