This is fabulous! You capture Sirius' utter in-love-ness so well, I love how Sirius is idolising even Remus' faults and even when he's trying to tell himself not to be mushy he can't help it. And I love Sirius' crappy flat (it has a very Lily Allen feel to it, and I do mean that as a complement!) and his joy at having Remus to himself. You've put it all across in such an immediate way, with the tense and the run sentences, it's like being there yourself, on the rickety tube train and in Covent Garden. It's just lovely to see them so content and together *huggles the fic and the boys*. Gorgeous!
