Do You Wanna Play Some Quidditch? (Part 2)

Disclaimer: I own nothing. A look at Sirius and Regulus's deteriorating relationship over the years. From best buddies to bitter rivals. I know I already did this, but I liked it so much that I had to do another version. This is set in a sort of songfic/ story format. But I just love showing how Regulus and Sirius started out so close but their ideals forced them apart. Review pls!
