Lost memories

A spell gone wrong (of course) during DADA class leaves Harry and Draco missing chunks of their memories-and accidentally somehow linked on a mental level. To avoid permanently losing themselves, they must enter each other's minds, sift through shared fragments, and (ideally) not spill their darkest secrets in the process.
Which begs the question: what really happens when two enemies are given the keys to each other's most intimate memories... and have to work together to lock them back up?

**OR** Harry and Draco are forced, to watch their most embarrassing, most intimate, but also most terrifying memories together -and along the way deal with the fact that neither of them is quite as terrible a person as the other thinks. And the fact that Harry looks so good in green and Draco smells like heaven really doesn't help.

Set in Hogwarts during their sixth year (let's age them up a little-just enough to keep things steamy without the moral crisis.).
