Yuuki really likes Fai! They met kind of strangely, just before the body-swap, which was awkward. But it helped her understand him a little better, too. Honestly, he reminds her a lot of Chairman Cross, what with his mask of smiles, so she definitely probably gravitates toward him, seeking a little bit of structure and comfort. Plus, he has to know what she is by now, but he doesn't condemn her for it. That alone makes her unbelievably happy, since she still wants to believe that humans and vampires can live together.

Radiant Garden is a bright place, but she might try to settle down around there so she can work for Fai. ;D
