Draco Malfoy is reborn.
Reborn back in the timeline where he first met his future wife.
Things to watch:
The author is a boaster about Hufflepuff, but he is not a critic of other schools. There is OOC phenomenon in the characters in the book. It is acceptable to criticize the author but refuse to criticize the characters in the book, especially the heroine. Knock on the blackboard! Draco's rebirth story, from Astoria's perspective, there is a private setting.
