Calum
to be totally honest i feel like calum would have zero or close to zero stress about the situation and you'd be the one to be freaking out like the night before and he'd just be like "babe, i got this." and brush his shoulder off and the night of the dinner he'd totally woo your parents and they'd be head over heels and your dad would be so happy because he used to play soccer too and your mom would whisper to you "good choice" aND later in the night after helping clean up you'd want to show him your childhood bedroom and he'd fiddle with all your little stuffed animals and he'd randomly ask "do you think they like me?" and he'd now have genuine worry etched on his face and you'd laugh and respond "like you? they love you.." and he'd sigh and smile and you'd try to be cute by saying "but not as much as i love you." and he'd chuckle and shake his head and come over to you and lean down to give a chaste kiss but you were like nah haha so you'd wrap your arms around him and he'd push you against the closed door while running his hand down the side of your leg and he'd lift it and wrap it around his waist and then your mom from down stairs would yell "dessert!!" and calum would mutter "i already got mine" LITERALLY BYE

Luke
little lukey would be so nervous oh my god like he'd be standing in the mirror trying to fix his hair and you'd walk into the bathroom and laugh while saying "babe, i don't think they'll be judging on how high your quiff is.." and he'd look at you with just such a nervous look on his face and he'd look down and go "OH MY GOD! MY PANTS! THEY HAVE HOLES!" and he'd run out the bathroom trying to take his jeans off and manage not to trip and he'd go digging for a pair of black jeans that didn't have holes and you'd come into the room like "luke." and he'd have his tight ass jeans have way up his legs and you'd just tell him "i love you so by default they have to love you, okay? and how could they not love you?" and he'd sigh and waddle over jeans still not pulled up and you'd both laugh and just stand in the middle of your room hugging and he'd kiss the top of your head this hurt my heart

Ashton
ashton would have some nerves but not too bad because he had meet your parents briefly before but he knew your dad was a bit of a hard ass so he was worried in that aspect but you'd reassure him and your mom would totally love him because he was really sweet with your little siblings and he'd even offer to help your mom cook and she'd be blown away because your past boyfriends were never this sweet and your father would be a bit skeptical so you'd squeeze ashtons hand under the table but eventually your dad would let up with all the questions because he took into account the smile on your face and how happy this boy made you this one was more cutesy but i think cutesy ashton is cute ok

Michael
michael YES PLS would be nervous because his hair is purple for fucks sake and he has a hole in his face but you'd laugh at him because no matter his appearance is he was a lil softie but would still be really nervous because he'd have war flashbacks to the time when your dad caught the two of you making out on the couch but on the night of dinner it'd be really quiet and awkward as hell until your little sibling i'm picturing a little brother would say "your hair is really cool! mom can i do that to my hair?" and your mom would cough and her eyes would be widened but michael would cut in and be like "well little man, i was actually born on a planet far far away and in my tribe we all have colorful hair but i was sent to earth on a mission!" and your little brothers face would just be lit up like a christmas tree with the biggest smile ever and you'd be chuckling and shaking your head at your lil dweeb of a boyfriend and even your mom was totally smiling and your little brother would ask "what's your mission??!" and michael would look over to you and say "to love and treat your sister right." and this would even make your dad smile too and your little brother would make a little gag noise and you'd be trying to keep your smile at bay while michael continued eating and reached under the table to squeeze your thigh gooD MOTHER FUCKING BYE

A/N: I'll post another one later today :))
