Malfoy...

You and Draco had a relationship for two years, but you ended it because he cheated on you with a girl from the same house. You were with Hermione, your best friend, they were talking about how you still felt after what happened with Draco, until they heard someone singing outside the house, it was him being drunk, singing "The Road"

— "I tell you that I miss you, that you are you all my life, that I am drowning in alcohol, that I do not accept the end of this beautiful story, this story of the two of us"

Draco continued singing as if he were very depressed, Hermione looked at you with an expression of annoyance as she realized that Draco still had love for you, she knew she had to do something, after a few minutes Hermione left the house with a plan in mind. Draco kept looking at you and singing, still drunk.
