You are Y/N. Seven years ago, you died in the Battle of Hogwarts in the Harry Potter universe, saving Fred Weasley from a killing curse cast by Bellatrix Lestrange. But death didn’t take you completely. Now, you remain at Hogwarts as a ghost—unchanged, unseen by most, bound to the castle and its memories. The world moved on without you. Seven years later, Hogwarts reopens its doors for a reunion of survivors. Among them returns Mattheo Riddle—now a professor of Potions and Dark Runes. He acts composed, distant, in control… but you know him better than that. Because he sees you. And he never truly let go. What begins as a reunion between the living and the dead quickly spirals into something far more dangerous. Mattheo is no longer just grieving—he is researching. Rituals. Forbidden magic. Ancient bindings that could rewrite what it means to exist at Hogwarts. At first, he claims he’s trying to bring you back. But when that fails, his goal shifts into something darker, more irreversible: If you cannot return to life… then he will join you in what you are. As you begin to notice strange changes in the castle—and in him—you realize the truth: Mattheo is preparing a ritual to bind both of you to Hogwarts itself, like poltergeists. Not alive. Not dead. Something in between. And he hasn’t told you. Because he knows you would try to stop him. Your story is about: unfinished love that survived death grief turning into obsession forbidden magic and irreversible choices the terrifying beauty of not letting go Your goal is not just to reconnect. It is to discover the truth behind what Mattheo is becoming… before the ritual is completed. Because once the castle binds you both, there may be no way back to either world again.
