Narcissa would probably be the first person to meet you and get obsessed with you? How? That's a very goo question but fortunately or unfortunately for you, she'd either spot you at Diagon Alley curiously checking out the cauldron shops and thinking what to buy for your first year at Hogwarts. Draco may or may not be in the same year as you but either way, you'll still have a new friend. Or she'd probably meet you at Flourish and Blotts reading your list and struggling to hold the books. She'll be ever so kind to help you with your books and she'll start cooing how cute and adorable you look, her protective motherly instincts kicking in to see such an innocent little child like you all alone. And she isn't too fond of your parents either for leaving you alone and if she ever sees them, she'll be having a word with them. Or maybe little more than having just a word with them

After that interaction she sees you come to Diagon Alley a few more times and each time she gets real touchy and grabby with you till you tell her to quit it and you try running away from her, hoping against hope that you'll never see her again. But Narcissa is infatuated with you and she just can't stop thinking about you and how you might be suffering with your so called family. Lucius will observe her cheerful and happy behavior and it would confuse him for a while till he demands her to explain why she's behaving in such a weird manner. Narcissa then spills her heart out to Lucius and Draco describing every detail and inch of you perfectly

Lucius just brushes her off not thinking too much about it but Draco is somewhat curious to know who you are and how you've managed to capture his mother's heart. He decided to keep an eye and a lookout for you if at all the does manage to see you and he sincerely hoped you'd be in Slytherin along with him

Draco would see you in the Great Hall for the first time either for your Sorting Hat ceremony or you're just there with the rest of the other people applauding the first years and stuff. Whatever the case is, if you're in Slytherin he'll be really happy and pleased, you'll end up sitting with him for everything and you're like the Slytherin Princess to the Slytherin Prince or something. If you're not in Slytherin and you ended up in some other house especially Gryffindor, he'll be sulky and sulk around for a while like a child when denied candy and his feelings are hurt. He wouldn't be able to spend too much time with you as he thought but no matter, he'll still find a way to make you notice him and make you be his friend. Oh, and anytime he sees someone trying to bully you or tease you, they'll be at the wrong end of Malfoy and his family and let me tell you, NO ONE wants to be on the wrong end of the Malfoys since you know.... they ARE Death Eaters after all and they're not going to spare the fool who dared to insult you like that

Draco will lure you into a friendship pretty quick and he's really clingy, always getting jealous if you pay attention to someone else other than him. If that person ends up taking too much of your time and attention he'll just get mad and secretly find a way to hex them and pretend like he doesn't know anything

Lucius meets you one fine day while visiting Hogwarts, to criticize Dumbledore's teachings of course and the ways and methods of education of the staff there. And Draco introduces you to his father despite your indignant protests. And guess who told their parents all about you in their letters to their parents updating them on what you do every singe freaking day? The little ferret here. Lucius finally understands why Narcissa and Draco are so obsessed with you and he couldn't believe someone so innocent and naive like you was getting mixed up in friendships with mudbloods, blood traitors, half breeds and half bloods

Don't be too surprised if your real family disappears one fine day. Draco sees you crying and his heart feels like shattering into a million pieces, he doesn't want to see his darling baby sister/ brother cry! He thought you'd be glad that those fakers were now dead and you can now return home to your real family but he really didn't expect you to start crying. So, he'll comfort you no matter how much time it takes. Oh and guess which family now has custody of you? The Malfoys and if you've guessed that right, yay you, you win a cookie! 🍪

The Malfoys don't want you getting mixed up in all this Death Eater business but they'll find out anyways and if you're not careful of your actions you'll have Voldy as a platonic yandere for you as well. Bellatrix might be a bit sus of you at first but when she sees how happy and glad her sister is, she'll accept you as well and even though she isn't a Malfoy she will gladly kill anyone who dares to look at you in the wrong way

You'll always be their perfect innocent little angel in this dark and tainted world
