Reason
If Kurogane is a solid, uncomplicated, perfect black sphere, Fay is fleeting, translucent, imperfect gray fog.
Kurogane says one thing and does one thing. Fay says one thing and thinkslovesdoes another. If Kurogane is true to his word, Fay is a very, very big liar.
Kurogane wears black because it is sensible, because it reflects what he thinks of himself. Because he thinks and knows himself a murderer, an avenger. It helps him creep around at night, it helps him conceal his brilliant silver sword. Fay wears white because he knows it's who he's not, because he loves conundrums and bleakness and being a hypocrite. It helps him dance around the subject, it helps him smile and look alright. If Kurogane shows the world who he is, Fay conceals himself down to the last detail.
Kurogane is here for one specific purpose: to return home. To Princess Tomoyo and beautiful Japan with its four seasons and red roofs and good tea. Fay is here for many specific purposes: to not. Not to a dead castle and a dead country and a not-dead King. As long as the road isn't icy, as long as it doesn't stench of magic and blood, Fay will go. If Kurogane has a path, Fay doesn't have one at all.
Kurogane's skin smells like clay and his eyes are shattered, broken urns. His arm is bleeding the reddest blood, and Fay, Fay laps it up. Kurogane doesn't shudder. Fay does.
If Kurogane loves Fay, Fay knows, and doesn't love back.
