Your prose in this fic is a little disjointed, probably intentionally, but it sparked my imagination anyway and, if I understood it correctly, it's a very intriguing, dramatic premise that you tease out in so few words... This is the idea that Hiro and Peter became lovers in the future, which was one lovely aspect of an otherwise dreadful future, a future which he is now attempting to ensure never comes to be, even if that means what he and Peter shared similarly will never come to pass. Hand me a tissue, would you? :( Future Hiro makes for a fine tragic figure and you create a strong sense of his self discipline in the face of his passion.
