Harry isn't any better when he's drunk

"I swear to Merlin if you barf on me Potter I'm making you walk home"
"Woo! I'm goin home with a hawt blonde" Harry staggered after Draco and Draco pulled Harry's invisibility cloak off his broom  "woah, where did that come from? Are you magic? I'm going home with a hot magical guy? Are we gonna ride on the broom like witches?"
Draco folded up Harry's invisibility cloak and put it in his bag before climbing on the broom "just hold on tight" he said.
It took a few tries but eventually Harry got on the broom behind the omega, wrapping his arms around the smaller male Draco took off and began flying back to their house. "Weeeeeee" Harry burried his face in Draco's shoulder "are you a siren? Is that why you're so beautiful and magical and whatnot?"
"No, I'm not a siren"
"So, are you single?" Harry asked
"No" Draco answered
"whyyy all the pretty ones are taken! It's not fair! Wait, if you're taken why are you taking me home? I'm not a homewrecker! I won't let you cheat with me, even if you are beautiful!"
"You're my boyfriend dumbass"
Harry gasps "we're dating!" He says in absolute astonishment "how'd I end up with someone as sexy as you?"
"I have no idea why I'm in love with you"
"You're in love with me? We should get married"
Draco abruptly stopped the broom "what?"
"I mean we're already dating, we should get married"
"Are you seriously proposing to me right now?" Draco asked
"Yes?"
Draco sighed "you really are wasted..."

~the next morning~

"Wha- where? Who? Harry shook his head, trying to get the hangover out of his head. He got up and stumbled to the kitchen grabbing a bottle of Advil
"Hangoverus begonicus!" Draco pointed his wand at Harry as he cast the spell "honestly do you forget that you can use magic?" He asked.
Harry set the Advil down "you never answered me"
"What?"
"Last night, as I recall I kinda proposed to you..."  Harry wrapped his arms around Draco, resting his chin on Draco's head as the omega cooked breakfast.
"It's fine, you were drunk"
"Well I'm not drunk now" Harry looked down at the omega "so what do you say?"
"I-" Draco's face turned bright red "yes, but you're gonna have to propose to me properly."
