They're very protective of each other, that's for sure. Molly might be the first one to meet you, or the Weasley children at Hogwarts. Heck, you might not even be related to the Weasleys and they'll still think of you as one of their own when they see the chance to make you theirs for good, you're just too naive and innocent for this world. And no doubt Harry and Hermione would play roles in helping them with their obsession with you as well since they are yanderes for you after all

Arthur would LOVE to talk to you about your knowledge of Muggles if you know about them that is. But don't worry, there are still plenty of other things he'd LOVE to talk to you about. It's actually kind of nice and adorable seeing him get so excited whenever you bring up the topic of Muggles, the way his eyes shine and light up with excitement like as if he's some sort of kid in a toy shop. But Molly has to be there to rein him in in case he makes you feel too overwhelmed with his questions. Arthur doesn't care if you're pure blood, related to them or not, half blood, muggle or heck even if your dad is Voldy himself. Unless of course, you're good. He'll still look after you like his own and care for you, and of course, keep you far far away from the prying eyes of the evil Malfoys and dangerous things like Death Eaters and concerning yourself with the activities of the Dark Lord

Bill is the chill and easy going brother who'll understand how you're feeling since he's a pro at it and he's also the oldest Weasley, he's the brother to 6 siblings of his. He's a good listener and always has good advice for you whenever you need to ask him about something and he'll also love it if you talk to him about his work and stuff. And he'll also tell Fred and George to lay back off a bit if their pranks become too much to which they'll apologize instantly. They would never think of hurting you, not even in their worst nightmares. And if you were brought into their family by force, he'll know how you're feeling and he'll make sure to always be there for you no matter what. Oh, and no dating, NONE of the Weasleys would ever allow you to date someone at all. Nope, you're their precious little baby and they don't want some riff raff tainting your innocence

Molly is a really coddling and protective yandere for you. She'll always make you nice hot lunches and meals when you need them, she'll always give you the comfort and love you need from a mother and of course, she'll get jealous when you talk about your past family. You just can't seem to hate her no matter what since she's being so nice to you, hating her would literally be a crime. She looks after you so well and that's actually part of a plan she has in mind. Oh, yeah, she's crafty too. She wants to win over your love and affection by doing these sweet things and all that, but she does truly genuinely care for you. And if you ever mention the name of someone you like, I seriously pray for that poor schmuck, be it boy or girl since I believe in gender equality lol

Charlie loves you as well and he's the adorable nerd, who'll like talking to you about dragons and stuff. Like Bill he's also laid back and easy going, and trying to make you feel more comfortable with the family. He'll tell you funny stories from his time in Romania, some of the hilarious things his brothers and sisters have done, their embarrassing stories and stuff that'll be sure to have a smile on your face. He would literally cry if you wanted to enter his field, he'd be so freaking happy and pleased, no doubt he'd actually say "IN YOUR FACE!" to the rest lol

Percy Weasley is the uptight stick in the mud, the spoilsport and sometimes the killjoy but he truly does want what's best for you despite him being arrogant and pompous. He tries to be a good example for people and his family but it's frustrating when no one follows him or even strives to be like him. He'll try to get you under his wing before the twins try corrupting you. He'll help you with your homework, ask you how your day is going and if anyone's bothering you, he'll teach them a lesson. He knows he isn't supposed to use his status as Headboy for personal reasons but he won't tolerate it if someone decided to make his sibling feel bad about something. And if you guys are at Hogwarts, he'll make his duty to check in on you every single freaking day and act like some sort of pompous watchdog for you

The fun loving Weasley twins, who love pranking you and the others, but will never go too far with their pranks for you since they would never want to see you cry. They're the best to come to when you're having a bad day or when you feel like crying. In which case they'll cheer you up by some of their pranks and make you laugh since they can't stand to see you cry and be sad. And as for the person whoever made the mistake of making you sad... they'll be on the wrong end of their pranks and NO ONE, I repeat NO ONE wants to be on the wrong end of their pranks, trust me on this. And they'll even take your opinion for their products at their joke shop Weasley's Wizard's Wheezes, and go as far as naming something after you and giving you some of their stuff for free, low prices or discounts ESPECIALLY for you. Lol, they'd just rub it in Ron's face and he'd so freaking jealous

Ron would be the really overprotective type for you. Normally the Weasleys are just over protective of you but he's INSANELY over protective. And it's mentioned in canon too that he's really protective over Ginny when she starts dating Terry Boot, Dean and Harry. And if you think he's bad there, he's WAY worse when you're concerned since the way he sees it is NO ONE is worthy of being your s/o, you're the baby of the family and he will NOT allow someone to ruin you. He'll love to talk about Quidditch with you and maybe even show off some of his flying skills to you, to impress you. And he will not think twice to defend you if some prat like Malfoy decides to be a prick to you, and what'll make his blood boil even more is if Malfoy decides to take an interest in you. In which case the entire Gryffindor house would have to get involved in trying to hold him, the Weasley twins and Percy from literally punching the hell out of him. And of course, with the help of his trust y friends Harry and Hermione they follow you with the Marauder's map and keep tabs on what you're doing just for your safety of course

And last but not the least, Ginny, the youngest of the family but knows how to get something when she wants it. And that includes your attention. She's kinda crafty and demands for your attention regularly. And she will snatch you up like some feather if you're spending time with someone else, except for Molly of course. NO ONE has the guts to dare to go against Molly lol. And of course, she'll introduce you to Luna and even Luna would turn out to be very protective over you. For someone who looks so innocent and calm like her, she does know how to get rid of people who bother you and make you sad. There's always someone watching you no matter what, be it a Weasley, a Granger, a Potter, or a Lovegood... they're all there for you and they're at the back of you, scaring people off who they don't like seeing close to you since all they want is the best for you, that's all. They might not have much, but they have family and it's home...
