He's so fucking perfect in all the best ways, even now, when they're both barely breathing against one another's lips like they ran a marathon.

You're my entire world, [he breathes, taking a moment to dive back in for another kiss before they part,] and I'm glad that, of everyone in the world, I can be yours.

[He's been wanting to talk about it. Getting a tag, or something, that says he has someone he belongs to. They're too far in it now to separate, in his mind. Ain's too... clingy. He'll never let go, no matter how much Vash asks.]
