In short, it is the happy campus life of Harry and the others after Lao Fu and his parents have done nothing for generations.
I don't care, I want to write about sweet love! !
Regarding Lao Fu, you can read the author's previous book "[HP] The Dark Lord's Young Lovers". It is very short and can be read in a while.
As for the author's writing style, it's really limited. Let's just make do with it. You are welcome to point out plot problems or ideas in the comments!
Purpose: Campus life without Voldemort would be so wonderful
