1: Friends

Rosie Lupin, Remus Lupin's daughter, is ready to transfer to Hogwarts with her father. He is the new Dark Arts professor. The reason Rosie has been home schooled is because she's a little different. She's autistic. She has trouble forming relationships with people, and often times when she does they don't understand her.

Fred and George Weasley, along with Lee and Angelina take Rosie under their wing. Fred, however, just takes more interest in the new girl.

All characters other than Rosie are JK Rowling's.

I will be mixing up the timeline as well.
