Everyone knows Beca had some issues letting people in, but Chloe could tell this was different.

Beca Mitchell plans to rule the wizarding music scene, but her stupid Muggle dad is insisting that she go to college. Well, at least Barden University has a halfway decent Defense Against the Dark Arts program. It also has the world's most annoying-but-compelling redhead, and Beca's not entirely sure how she feels about that. Not so much an HP crossover as an HP infusion. COMPLETE

AU. Quiet Beca and outgoing Chloe are an unlikely pair of best friends - have been so since middle school. But when Beca is diagnosed with cancer right before her senior year, she shuts everybody out, afraid of the pain her possible death could cause despite newly aired feelings between the two friends. And really, it's no surprise that nothing works out the way she wants it to.

"Beca always ends up obnoxiously blasting her music through the apartment, and you become irritated, shouting at her to turn it down over the vibrating bass line." Beca plays the beat to Aubrey's heart, maybe a bit too loudly. Tragic Mitchsen oneshot.
