I read this a while ago, and can't for the life of me remember the title!
It opens with Lucius and Hermione in a carriage (?) after a big event, and Hermione has a like something like "I think it's because you're bad in bed"
Plot follows: post war. they've been friends for years, Hermione lives in the Manor, and everyone else thinks they've been sleeping together the whole time, but they're 'just friends'. They give it a shot, smut ensues, and a happily ever after.
Anybody? Anything?
Thanks for the help.
