Following the ending of JKL Episode 7, Harry did kill Voldemort. The story begins here. Harry did not have children with Ginny and live a happy life, but died with the remaining Death Eaters. Somehow (because I can't think of any creative reason) Just don't explain), Harry traveled through time and space to his parents' time (1970), and then found that he actually had the opportunity to go to school with his parents. He also remembered Professor Snape who loved his mother and sacrificed for everyone, and decided to help Snape and let him have a happy school life.
All in all, the story revolves around Lily, the four robbers, and the relationship between Severus and Harry. It is as ambiguous as possible, but there is one thing. It is absolutely impossible for me to pair James and Harry because I don't like them. If you feel that James is too gentle towards Harry in the article, please believe me that it is a father's love for his child. I am not sure who Harry wants to give it to (I haven't thought about it yet). Anyway, it will be a long time ago (irresponsibly ran away)
I plan to write a warmer article. Readers who want to see some exciting plot scenes may be disappointed. Moreover, my writing speed is a bit slow. I advise you to gain weight before reading.
