I love them. They're, depending on the day, tied for my favorite couple on the show, or they're second. I think a good chunk of it is the fact that Tara's not a tooth pick, like everyone else on the cast, and it was nice to see someone who was built a bit different get a nice relationship. Also, the character I relate to the most, aside from Buffy and her problems, is Tara and hers, albeit not to that extent, so she ended up being one of my favorite characters.

Anyway, don't worry, I won't de-friend you for this answer ♥
