I realize this was written quite a while ago, but I was surprised to see that I had never left feedback on it.
I've read this fic at least half a dozen times, and it's still wonderful. The characterization is spot on and, really, the world can always use more Angelus/Wesley.
If you ever planned to write any more of this story, I would love to see it. Or any other BtVS/AtS fic you post. :)
