I think I was reading this fic over at VK, so I'm glad to have found it again.
Can't quite see Jenny Calendar and Angel together somehow and I see they are having the same trouble. Are Willow/Oz/Tara a threesome? That would totally rock.
Oh! A Goddess wants to 'fix it'! Well that explains it. I wonder how much she's going to tell them of 'what might have been'...?
