This isn't a pairing I often read but it was recc'd to me for having a very good Sirius. I was not disappointed! Your Sirius is fantastic! I very much enjoyed your characterization and the slow development of his relationship with Snape. I love the banter and the snark. I love Sirius' change in attitude and how he approaches Snape. The plot was interesting and engaging. Just a really great fic that I very much enjoyed.
