III. "Difference"
Leaning up in bed, Orihime observed Ulquiorra by the luminescence of the moon. She knew Hollows didn't sleep, and wondered if Arrancar were different because they were more human. Either that, she thought, or he was only pretending to sleep in order to provide her with a sense of familiarity. The second seemed a little farfetched, so she went with the first.
Trailing a finger over the tear-streak marks on his cheeks, she took the moment to notice the similarity between the hue of the linen sheets and the pallor of Ulquiorrra's skin. Both were a ghostly white, especially when basked in moonlight. She watched as her hand, wrapped in the unfamiliar color of her own skin, contrasted with Ulquiorra's. She noticed, too, as her hair fell over her shoulders and onto his chest, that even that was drastically different from his coal black locks.
Glancing up at his peaceful face, she wondered if the Arrancar dreamed. Noticing the slight twitch of his eye and then the rare, wan smile that spread across his lips for only a fraction of a second, she decided that they either did, or that he wasn't sleeping at all. Nestling her head back into the nape of his neck, she breathed in his barely-there scent and smiled. Despite the differences in their appearances, or even in their personalities, she could take solace in the one similarity they shared: they would still love each other in the morning.
