HP: The Dark Lord in My Head

[Harry Potter] The Voldemort in Harry's head died, perishing alongside the Dark Lord in the Forest. But the Boy Who Lived woke up in an orphanage... and began his life anew. There is still a Dark Lord in this world. But the prophecy's Chosen One has two possible candidates: Longbottom and Potter. The Death Eaters and the Dark Lord went after the Potters and the Longbottoms, respectively, to ensure there would be no future threats. But will things turn out completely differently this time? The wizarding world's Chosen One is now Neville Longbottom. James and Lily are alive, but their only son is missing, and they lie unconscious at St. Mungo's. Sirius is still suffering in Azkaban. Scabbers is still doing very well as a pet rat in the Weasley household. The Death Eaters remain silent, awaiting their Lord's return. It doesn't sound very good, but everything is heading in a better direction. "Hey! Voldemort! What are you doing in my head?" the green-eyed Chosen One shouted angrily into his mind. "My boy, you can't expect me to watch a bunch of lions without getting upset." A chilling, strange hiss sounded directly in his mind. Who knows why a Dark Lord is living in Harry's head! Who knows why Harry has to relive his past life as the Chosen One just so the Dark Lord in his head can live a good life in this world? "Little boy, you are the one chosen by the prophecy. You are the only one who can stop the Dark Lord~" said a certain Dark Lord, completely unconcerned. In this life, he has parents, friends, respected mentors, and a lover who will never betray him. Of course... the other Dark Lord out there, the one who split himself into several pieces, is a bit of a nuisance. "Boy, you could at least not say that in front of me!" Voldemort was rather helpless against this sly lion. "Oh, of course... but I wasn't talking about you!" the mischievous green-eyed Chosen One retorted. Just look! What could be happier than this? This is a story completely different from the original, one with no more regrets! The Potters will watch Harry grow up! The Professor will let go of the past! Sirius won't fall through the Veil! The Headmaster and the old Dark Lord won't be estranged anymore! This is a wizarding world where everyone is happy!
