After almost 11 years Pansy, Blaise and Theo all get worried from not seeing Draco since he was 18, so they start looking for him. And when they find him they are shocked to figure out everything.

What if instead of the Dursley's that took Harry in when he was a baby was a Sirius blacks ex girlfriend and James potters twin sister Y/n Persephone Potter

Your cedrics little sister you join hogwarts late because you were too sick to go and teachers at Hogwarts agreed you can come if you get better, you did and now your starting Hogwarts (My sister who has health issues helped me write this and based it off her health issues and kinda how she struggles, not completely because it's personal)

You and Draco have been having a secret relationship for a few years, why? Because your Harry potters twin sister

Your y/n suoh your tamakis daughter but he doesn't know you exist since your mother and your dad broke up when she was pregnant with you and now your mother is super busy with work and everything but when you turn 14 you meet a boy named Ayato Hitachiin and become friends with him and you go over to his house one day and meet a man with the same last name as you and your mothers secret starts to get found out (Again ages are gonna be off)

Neville has a girlfriend named y/n and what he thinks her last name is l/n until he finds out its not true and everything starts changing
