Remus uses his camera everywhere, he rarely leaves home without out, but has a habit of taking photos of Sirius/with Sirius in. And Sirius never really knew why, until their wedding night when Remus gives him a huge scrapbook of hundreds of photos of them and Sirius and they’re all labelled and there’s small passages from big anniversaries, when they graduated university, when they moved in together, getting their first pet etc and Sirius is in tears he loves this man so much
