2 Works in Harry Potter/Luna Lovegood
The pairings in canon got a bit tight and close and...honestly, quite weird.
Let's loosen that up a bit, maybe add a dose of reality or three, plus some books, coffee, and mysterious creatures.
(More than three doses. Yes, yes.)
Harry's more broken than he would care to admit, after the war ends; Luna seems to be the only person willing to let him heal on his own schedule.
