So I have this headcanon that Draco constantly complains about Harry’s fashion sense because Harry absolutely loathes dressing up. So on their anniversary, Harry goes all out, using Draco’s hair potions and buying new glasses and putting on a fabulous suit.
And at first, Draco’s impressed and excited – even turned on – but halfway through dinner, Harry notices that Draco keeps looking at him oddly. When he finally gets frustrated and asks, Draco frowns and blurts, “You look fucking weird,” before reaching out to muss his hair and loosen his tie. Then Draco settles back and studies him and, much to Harry’s bemusement, finally says, “I don’t suppose you brought your other set of glasses with you.”
Because I dig the idea that the things that most irritate them about each other are also the things that they most love.
