   Summary

   James is best friends with Sirius. He never meant for this to happen. For him to betray his closest friend and accidentally fall for his brother.
   Regulus watches James from across the Great Hall, painfully aware that he is everything James is supposed to hate: a Slytherin, a Black, a future Death Eater.
   The slow burn is built on stolen looks, intellectual rivalry, and the horror of realizing you love someone you’re meant to destroy.
