i liked this. you did a nice job with conveying the hurt and vulnerability. and i liked sirius taking him chocolates in the hospital wing. aside from the boyfriendliness of the gesture, it also referenced PoA with the chocolate and the dementors. let's never forget, chocolate is a powerful magical substance in its own right! (now i can go read the sequel) : )

You could have added more chapters and continued the story because this is pretty good.
