I don't know how to write it, so I'll just give it a rough outline.
Lowell, a Hufflepuff graduate with all O's, returned to school again to become a professor of the Care of Magical Creatures class.
He was very good friends with Lily Snape during school, and Harry would be taken to live with her.
The timeline of the story is from the child era, interspersed with memories of the parent era, the timeline is seriously messed up, and will be full of superhero stories.
There is no CP. At least there will be no clear CP in the text. Feel free to criticize it as long as it does not affect others.
Thank you for liking it. If you don't like it, just leave. Don't scold me. Thank you.
Intention: Just write if you want to.
