This was really sad, and in a way, a more believable version than anything else I had ever read. The guilt in Remus's words is terrible; you can tell how guilty he felt about Sirius, how he completely forgot about how Sirius didn't trust him and instead focused on how he was a terrible friend. And Sirius - that one line, "your eyes are even sadder than they were back then, though I never thought it possible", that was heart-breaking.

Love for you. <3
