Hey hope you are doing well. I am looking for a christmas carol inspired fic. Not sure if I read it on ao3 or ff.net. In it Harry goes to past present and future. In past he sees draco getting off to his tie or shirt? And in future he sees thar draco is married to some man that is not him obv and is sleeping in his bed. And he goes snooping around and he finds the tie or shirt from past that draco still has.
