[At least her response is one he more or less could see coming. He won't leave, though. Not here and not home. Never again.He can only hope that she'll (continue) to accept him just as well.
So he lets her speak without interruption.]
I'm not the same as I was when we met.
[She knows that especially well. He's so, so far from that.]
I never did hate you. I- [. . .] Sometimes what did bother me was how close you seemed to be with him, although that was more specifically when we were still rather young.
[He pauses again. Brows slightly knit.] But you know, Yuuki. I had always truly believed you would continue with him along the same path. I wanted to support the two of you even before you returned to being a vampire and gained back your memories. I disregarded my own feelings for you.
[He faintly smiles as well.]
I know you don't want to think of this point in time, but- in the moments before he gave his heart to the furnace, he had embraced the two of us. [Granted it was very strange from Zero's perspective.] He had said that he never thought that my feelings for you would have turned into what they did.
[While also telling them both that he wanted them to be together. But that's not something Zero really needs to add on right now.]
