Hmmm. Well, I don’t really ship Draco x Luna (I always thought they were
related, but maybe I just thought that because of the hair colour), but I’ll
see what I can do. And I can hardly not
do Drinny headcanons (otherwise @weasleyismyking540 will have my guts for
garters).
(For the purposes of this, Draco Malfoy is effectively a nice bloke with
Draco’s name and appearance. Canon!Draco is a jerk, and I don’t want him
anywhere near the other three in a romantic setting)
Harry and Ginny, of course, were dating. That was fine; they were in
love, after all.
Then Luna Lovegood entered the picture. Well, that wasn’t strictly true.
She had always been there, after all. She’d been Ginny’s friend for ages, even
before she met Harry. Ginny had always been close with her. Ginny had always
insisted to herself that Luna was just a friend, but her arguments always
sounded half-baked. As if she couldn’t quite believe it herself.
Not only that, but Ginny was also very much in love with Harry. But
Harry could tell that Ginny and Luna had something going on beneath the
surface. In the way they looked at each other. He could tell because the same
thing happened whenever he and Luna looked at each-other.
To complicate matters, Draco Malfoy then appeared. He was there, with
that blonde hair, and those intense eyes. Good-looking and he knew it. Harry,
Luna and Ginny all knew it.
Draco was cool as a cucumber. Except when he was around Harry, Ginny and
Luna, of course. The bloke would blush like a tomato. Trip over air. Needless
to say, it was entertaining to watch.
Eventually, Ron and Hermione had to lock the four of them into a room.
Four hours later, the foursome emerged as a poly relationship.
The four of them eventually brought a house nearby Ottery St Catchpole
(Harry, Ginny and Luna wanted to be near their families, and Draco wanted to be
away from his family, so it was perfect).
They had to magically extent the bedroom so that they could fit in a bed
big enough for all four of them to sleep in (Luna suggested bunk beds, but the
others managed to talk her out of him).
Luna had to implement a ‘no more than one in the shower at any given
time’ rule, because the resulting… “events” made them all late for work.
On rainy days, they all snuggle up together on the sofa and watch muggle
movies. Usually rom-coms (Harry takes great delight in seeing the other three
react to them).
All of them are of the opinion that the other three are better looking
than they are (yes, even Draco thinks this).
Their bed once broke during a particularly… enjoyable date night, resulting in a not-very-impressed Ron and a
very-embarrassed Hermione having to magically re-structure and strengthen it
the next day.
Sometimes, Harry and Ginny can’t tell whether it’s Luna or Draco’s hair
stuck in the shower (it’s usually Draco, funnily enough).
Luna works from home (doing artwork), Ginny works for the Harpies, Harry
is a teacher at Hogwarts, and Draco a columnist for ‘Witch Weekly’.
Harry, Luna and Draco always cheer Ginny on during her matches, wearing
dorky t-shirts saying ‘our girlfriend is amazing!’.
Luna, Harry and Ginny always compile Draco’s columns. He blushes
everytime he sees them cutting said-column out of the paper.
Ginny, Harry and Draco have all posed for Luna at some point. And before
you ask, yes they have done life
modelling for her, but that’s really no-one’s business but theirs.
Draco, Luna and Ginny often turn up announced in Harry’s study at
Hogwarts with a picnic. It’s not uncommon for students to see the four of them
sat out on the front lawns in the nicer months of the year.
Ginny likes it when the others kiss her neck.
Luna likes cuddling the others.
Draco likes snogging the others.
Harry likes putting his head in the others laps.
Thanks for the ask, @whatifdestiel! Hope you like these! (Sorry it took so long for me to respond)
