Why it's sublime... This is an AU story that really works for me. Angel's a vampire, Buffy's a Slayer, but not much else is familiar. Oh, except that Buffy loves Angel and Angel loves Buffy...and that first kiss. Gah!
Why it's sublime... This has been called B/A for adults, but I think if you don't see B/A as, at least sometimes, dark and complicated, you're missing the point.
