All pairings are possible across both the Marauders' and next generations. The female lead transmigrates, but has an inseparable connection to the original story.
After an accident sends A En transmigrating to the magical world, she thinks she can make it to the end by relying on her knowledge of the plot. But then she discovers that Harry's parents are alive, Lupin isn't a Hogwarts professor, and Black has become Deputy Minister of Magic. All A En can do is look up at the sky and sigh.
The female lead is self-serving but doesn't harm others. She's warm on the outside and cold within, and loves herself most of all. She will use other people's feelings for her to achieve her goals.
Warnings: The writing isn't very good. All the male characters are a bit love-struck, a female character will fall in love with the female lead, there are extreme romantic relationships, canon pairings are broken up, and some minor characters from the original story are reimagined.
Characters tentatively planned for romantic storylines: [Harry, Hermione, George, Cedric, Blaise, Sirius, Remus, Peter]
Characters tentatively planned for special relationships: [Severus, Lily, James, Regulus, Voldemort]
The female lead's friend Delin is the protagonist of another series.
