[Because he does. He believes every last word that he speaks. If he didn't, even in the slightest, then he wouldn't have put his voice to them.]
Because you've always been there for me even in my darkest hour. Even when I wanted nothing more than to disappear.
[Much as she feels right now. He shifts his hand a little so their fingers lace, the hold firm while warm.]
Because I— [Because he's loved her ever since. The feeling having begun to stir even within the first day or so after they met. Not that he knew how to take or see it as.
But the word isn't something he can quite tell her yet. She does know; it's within his blood that she consumes, and one thing he wholly is unable to hide.
Its only that speaking it aloud could be dangerous all the same. Now, though, even in her misery, she may be able to tell how close he is to telling her.]
Now it's my turn to be there for you. [As he said earlier. It's probably selfish of him.] For just now, for years upon years. All I want is for that. Even while you're at your lowest and need to be carried; even if you don't truly believe a word I say.
[His hand tightens with hers just a little, head tipping forward.]
. . .even if it takes you forever to believe them, too. I'll always be yours.
