[ Kaname is an... extremely complicated topic for, well, any of them to have. The fact that Yuuki comes from his past- from all of their pasts just puts her in such a delicate sort of position that Aidou has to constantly be aware of just what he is and isn't saying to her. The same goes for Kaname, really. Luckily, Zero is someone he can at least not have to skirt around certain topics with and for that he's rather thankful.

How, despite the love that he figures she'll always feel towards the pureblood, she stands for what she believes in and doesn't waver much once her mind is set on it. Which, again, sometimes annoying but, in the end, he could only stand by her and even come to her aide when others thought her foolish. ]
