There is no male protagonist in the main text... (Probably). It feels very immersive. The heroine in the first and second episodes is very similar to our thoughts when we suddenly travel into HP. Either we are very close to the protagonist, or we are far away, hoping to spend our lives safely.
Draco the hero. The heroine is cute! Although I think the heroine is not very Slytherin-like, but thinking about Draco, I feel like I have a stereotype of the four major houses. Everyone has different qualities and is not limited to one. In short, it's less cruel and more sweet.
Professor's text. If we want to save the professor from being so gloomy and miserable, it is indeed more logical to start contacting him from his father's time. The setting of this book is related to time. The logic of the grandfather paradox shows that time is always the most unsolvable puzzle.
Draco the hero. I once wanted to make the professor the male protagonist, but when I think about it, it will definitely not happen. The female protagonist and Lily are too similar in appearance, and they will never get around the stunt. Just thinking about it makes me collapse.
