ASHTON
They would be really sweet and she would be someone who could make ashton laugh all the time and she'd be cute as hell because ashton's so adorable but he'd worship her and tell her how beautiful she was all the time because he's so sweet she'd be friends easily with everyone and she'd get along really well with calum because that's ashton's best friend and she'd get to wear ashton's beanies and his bandanas and his stupid ripped up shirts and flannels that smell like him
CALUM
She would have to be really outgoing and sassy and she wouldn't be afraid to be herself. It would be kinda like she had no filter on her brain and she just said what she wanted without regrets because i think that's kinda how Calum is. She would be accident prone and mistake prone, but Calum would just laugh at her clumsiness and help her pick up the pieces to another dish she dropped in the kitchen. She would like sports and maybe even play them because Calum's really into soccer (football for all you across the pond) and she should be able to keep up with him. She wouldn't take any shit off of Calum and she could hold her ground against him in any argument they had and she would normally win because Calum wouldn't be able to stand being mad at her for very long and if he was mad at her it was over something really stupid like how she didn't snuggle him long enough that morning or that she forgot to call.
LUKE
She would be more shy and quiet because that's how Luke is and they would've had a really hard time admitting that they liked each other and they were finally actually really relieved when Calum shoved them in that closet and wouldn't let them come out until they had talked to one another and Luke would be so sweet to her and hug her all the time and kiss her every chance he got and she would be Luke's best friend because they would be really similar and he could talk to her about anything really and vice versa and she'd love to let him carry her on his back and Luke would call her his monkey because of that
MICHAEL
She'd be a very laidback individual. She would have to love sleeping in until noon and cuddling all night because michael would be a cuddler I mean look at him he looks like a cuddly kitten and she'd have to be cool with like leftovers for dinner sometimes and going out for dinner a lot because lazy and sometimes cold pizza for breakfast and maybe lunch too. She would like video games and maybe even play them, maybe she's a gamer girl and that's how they met. She'd love to let Michael play guitar for her and sing to her because i think that's a cute way that Michael would show his affection and she'd be cool with snuggles on the couch and forehead kisses and nuzzles from Michael's scruff
