Harry Potter...?

Harry and you are 'friends' or something like that, since you were from Slytherin, better known as the 'Rebel Prince' because you were the only one who didn't use a cold, cruel demeanor like Malfoy; instead, you were relaxed, intelligent, a prankster, and occasionally serious, with ideas that differed from the blood status norms. For some reason, you and the Golden Trio formed a friendship, as you watched over them and supported them during their depressing moments. However, you fell into heavy addictions like alcohol and dr0g@s, and you skipped class almost all the time.

Harry along with Hermione and Ron saw you almost as a friend, because you supported them and being so intelligent, you gave them quick and simple solutions, he was well known throughout Hogwarts with your such a relaxed, livid, fun and kind attitude as well as for supporting some although you very rarely went to class due to your relapses, you were thin, very thin but without a doubt you were fun and always made anyone smile

Harry saw you and smiled, waving from afar
