Metronome

Remus is an artist. He can't draw worth his life, but that doesn't matter. He makes beautiful art with his age-old piano in his living room, where he does community lessons with the kids in his neighbourhood. At least, he did. Between medication and therapy for his Intermittent Explosive Disorder, Remus finds himself deep in debt and financial stress. Unable to continue living in his current home, he is forced to pack up and move into a studio apartment on the other side of the town, taking up a job as a music teacher in a public school not exactly known for its extracurricular budget. Between that and the recent complications with his mental state and his heart condition, the last thing he needs is a new, extremely attractive neighbour, much less one that seems to have a very personal secret, but of course, that's what he gets.
Sirius has no time for a relationship. He has no time for love. He has no time for the new neighbour that seems to be glancing at him out of the corner of his eye every time they pass. The only thing he has interest in is a man called Peter: a man that betrayed his best friends to the notorious Riddle Mafia and is now on the run after faking his own death. Sirius knows he's out there, and he knows that he's guilty, but until he gets his man, he can't prove anything. But there is another man pushing his way into Sirius's head: The new neighbour, Lupin, who seems shy and timid, and yet has periods of loud screaming and banging coming from his apartment every so often. Sirius is intrigued, but he finds that he is unable to focus. Will Lupin be his saving grace, or will he be his destruction?
