Hi! I'm looking for a Harry Potter fanfic where Harry has a brother that was declared the Boy who Lived. Harry is the real boy who lived but nobody knows and Harry's parents survived the attack. Harry was sent to live at the Dursley's and I'm not sure if his family picks him up when he receives his letter or if his parents recognize him when he enters Hogwarts. I think his parents taught at Hogwarts and they are actually sorry for giving Harry away. Harry doesn't want anything to do with them. I think that pairing is Harry Potter x Tom Riddle. One day Harry was attacked by a vampire but Harry managed to defend himself. The vampire was Sanguini and he needed blood (which was why he attacked Harry and was so close to death) so Harry willingly offered his by either slitting his wrist or offering his throat to put at Sanguini's mouth. Afterwards Sanguini is very affectionate with Harry. Several chapters past and Harry meets King Dracula who sees how Prince Sanguini regained more life after Harry saved his life. Dracula hopes that Harry will keep living because he is worried about what will happen to his son (Sanguini) if Harry dies. Harry's brother doesn't like how Harry came back into the Potter's lives because he considered everything to be okay before Harry came in. Lily was admitted to St Mungo's for mental health issues and James was sadder because Harry won't give them any time of the day. I forgot what Harry's brother's name is. This is all I can remember. Can anyone help me find it? Thank you!
