Hannah Potter and the Goblet of Fire

Author's note (IMPORTANT AND CW!)

AUTHOR'S NOTE:
Okay so this story is set in fourth year however all the characters are 15. This is not an x reader/self insert story :( (though it can be read as one!) the main character is Hannah Potter, Harry Potter's twin sister. The main love interests are Draco Malfoy and Severus Snape. Severus Snape is still a teacher but in this book he is 26. I have created specific descriptions of the characters to fit my idea for this book. If you don't care that's cool nbd, but if you don't want to be grossed out by the idea of old greasy Snape being your love interest you may want to read. Finally, before the description of the characters here is a

~END OF CONTENT WARNING~
Okay so with that said and done here are my (not very in-depth character descriptions). One thing to remember is that I created these to help ME set the scene and visualize how I want the story to be, if you don't like these descriptions feel free to ignore them they are not necessary :)
Severus Snape: A 26 year old potions teacher who hates the Potters(unless...) He is 6'3 and lanky; however despite that he is still fairly muscular and surprisingly so. He has long black hair that isn't greasy and he doesn't have a hooked nose. He looks young but still aged from experience with dark circles under his eyes. You can often find him outside the school with a cigarette, reading a book in his study with a glass of fire whiskey, or hunched over a bubbling cauldron.
Draco Malfoy: A 17 year old, 6'2, pure blood with ice blue eyes that could kill. With neatly groomed platinum blond hair he's the boy of every girl's dreams. Surprisingly so, he is also the party boy of the school, attending every party that he deems "worth it" you'll never miss him in the crowd. He could be considered an 'eboy' with his pierced ears, ringed fingers, and chained neck, he could probably be TikTok famous.
Hannah Potter- younger twin of Harry Potter by 3 minutes she's somewhat of a wreck. Sorted into Slytherin she quickly became friends with our favorite blond Draco, ever since then they've been the party animals of the school always having a good time. With baby blue eyes matching her brother and mother (Lily and Harry are going to have blue eyes because god said so), long dark brown hair, freckles, and a nose hoop it was easy to tell who was the rebellious one. Chosen as the seeker on the Slytherin quidditch team members of her house couldn't tell wether to love her for her skill or hate her for her blood status.
Harry Potter- older brother of Hannah Potter he is just a 5'11 version of her with glasses, it was no doubt that they were twins based on looks alone. However what really sealed the deal was how much they care for each other despite house differences.
Omg I'm done that was so annoying and took way too long but basically Hannah is stupid with Draco Harry is like stop but Draco is also like ew omg ur blood is trash and Snape is all like ur mom was sexy so ur sexy? Idk this is just word vomit at this point I promise it will be good pls lmao. Also I am so sorry I did not mean for it to be this long of me just saying that Draco is even sexier than normal and also Harry has a twin :/
