Zero would never mean to have his heart catch the way it just did. The feeling was foreign, yet not entirely. He didn't really want to think too hard on it, either. There was just the fact that it definitely happened, and there was nothing he could do about it, nor to even prevent it from happening again.

Which was even worse, because he had to refrain from returning the affection. The fact that she was not 'his' Yuuki remained ever clear at the front of his mind. She was not the Yuuki he had kissed before, nor danced with at a masquerade. She wasn't the Yuuki who had at one point taken his memories (an act which Zero had by now moved past; there no reason at all for him to linger on that event). The only constant, though, was she was still the Yuuki he loved; still the one who always had, and will, consume him whole. Human or vampire, it didn't matter. She had never gone against him, even during the time when he had, to her.

"Ah. . ." Quiet. He knew what she meant. Still, the proximity was both jarring, and a comfort. She wouldn't ever not be that way to him.

"I guess I might have been lost without Yuuki to help, huh." Beyond the mild amusement, though, the words felt all too bittersweet upon his tongue, their taste lingering throughout him. As if her were mourning her in those moments.
