HP: Me, the Savior?

What is it like to be the famous savior? A certain professor: "You mean Harley? That is my best student. Like her mother, she is an excellent potions master." A certain know-it-all lady: "Harley is my best friend. She has a superb level of magic. Almost everyone in the magic world knows her name." A certain red-haired wizard: "I want to say that without Harley, I would not have succeeded at all. She encouraged me. I will take this opportunity to ask her -" "Keep your giant head filled with splendens away from my dear student!" A certain professor knocked the red-haired wizard hard on the head and stared coldly at the platinum noble opposite who wanted to say something. Malfoy: "..." The savior himself said: "If possible, I just want to be a salted fish. How nice would it be to lie down~" Speaking of this, the beautiful black-haired girl smiled sweetly. "But we all know that's not possible." Things to note: Harry's sex change, heartthrob, CP Draco, Snake Yard, slow-burning, many private settings. The follow-up involves other film and television works, but they are all branch lines. Baozi who is not interested can skip the chapters directly. Currently written branch: Transformers (TFP)
