Odi et amo
Unrequited love can be very many things, including pathetic and narcissistic - one can fall in love with beautiful suffering at the hand of a belle dame sans merci - but the one thing it can never be is truly long-lasting.
Ishida Uryuu, dragon of rain, dragon of tears that never will drop, is weeping blood from his belly; his whole universe compressed into the voice of the woman he loves - never girl in his mind, for some reason, always 'woman' - breaking through all his beautifully constructed barriers of hope and denial and forcing him to acknowledge the truth.
"Kurosaki-kun!" she says over and over and over because the truth is that Ichigo is not the centre of her universe; he is her whole universe and no-one else is real to her now except the monster that she turned human in his death, and even he only for a fleeting moment of mercy, soon forgotten.
And he, Uryuu, what is he for her?
He had come for her, a shining white knight on an impossible steed of reiatsu; he had saved her again and again; he had gone up against the monster, knowing full well he hadn't a chance, to buy time for the real hero of the tale; he had tried to stop the hero-turned-monster, only to get skewered like a pig… and for what? To hear his rival's name repeated like a mantra of desire, despair, obsession, love… and for him not even a passing glance, a fleeting easy compassion.
Ishida Uryuu, who barely existed for Inoue Orihime, has ceased to be real to her. He is nothing.
So, weeping blood like rain from his belly, a spectator in a tragedy where there's no role for him except the ridiculous one of the self-deluded hero wannabe, Uryuu hears his remorseful rival offer himself to the monster in atonement and is treated to the view of his lady's uncompromising back.
He does love her; he loves her so much, so very much, but he has never hated anyone with such a lethal concentration as he hates her now.
FINIS
NOTE: The title is from a poem by Catullus which says: "I love and hate. How this is possible, I don't know, but I feel it, horribly, and am in agony." - La Belle Dame Sans Merci is a poem by Keats in which a beautiful fey lady (actually tuberculosis) entices young knights and sucks all life out of them until they are nothing more than pale ghosts. - Kubo-sensei could have remembered he had Ishida bleeding to death amid general indifference there, y'know?
