On the one hand, I want to beat you to death with a thin-bottomed cauldron for ruining the suspense of how Harry and Lotus would meet, and how Harry and Luna would bring Lotus into the relationship.
On the other hand, at least that crap won't be the focus of the story, and that means moar smut (or at least it SHOULD mean that). As that's the only complaint I have atm, 5/5.
