[Harry Potter] Nesting

ABO, the classic Alpha/Omega pairing. Everyone's got a one-sided crush on Harry. It's called No CP, but we all know what it really means. After presenting, the Chosen One discovers that his things keep going missing. He assumes he's just careless, but in reality, a certain cruel adult who has long suppressed his desires is secretly collecting them and building a nest in a dark place, filled with Harry's scent. An insatiable hunger, love and hate intertwined. Content warnings: 1. Harry is the adored one; the story centers on him, and Ron/Hermione is not endgame. 2. Harry is not a typical Omega; there are original settings. 3. No children, no plot progression, just a romance. 4. Because of the soul fragments, Harry and Senior Tom will have some interaction through their pheromones, but it will never go beyond a spiritual connection. Theme: Being taught a lesson
