For one, there is a small itsy-bitsy note I find while reading this first chapter.
Your "Or was all of it all of me?” could be better phrased as - was all of it ME?-
And second, reading through it kinda makes one feel like its an AU--alternate Univers-for the reason that its a scene after the WAR and you wrote in Harry and Ron having a convo like they are talking about quidditch. Shouldnt there be more emotions, stronger and more compelling that hounds Harry than what appears to be mere weariness in the fic? Like say, brooding anger for having just killed someone, or seething menace brewing just beneath the surface?
Just a note there, mate. I love reading through your fic I look forward to reading th e next chaps.
