Up to No Good

Theo Nott has a little sister (terrifying). She's a half sister from an affair of his father's, so while their father sees her as a mistake, he sees her as the anxious little girl who showed up at their door not long after his mother's death. Needless to say, despite her self-sufficient, rebellious, and perfectionist nature, he looks after her like nobody else. So when she transfers to Hogwarts after years at an Italian witchcraft school for girls, there's just a touch of trouble, particularly with that Riddle boy.

IMPORTANT NOTE: I don't have rights to any of the characters or anything Hogwarts-y from this. I made up the one girl but pretty much the rest of it belongs to J.K. Rowling and/or whoever else is in charge of Harry Potter and the like. I REPEAT: THE VAST MAJORITY OF THIS IS NOT MINE.

NOTE 2: My interpretation of the characters is from TikTok, so while the characters are probably very poorly written out, hopefully the writing and story is mildly entertaining. I literally came up with this thing on a whim and couldn't get it out of my head, so here we are.

Enjoy!
