Do you ever just like think about how nice it would be to be bestfriends with some idols?
Like Seoho from Oneus. The most adorkable bestfriend ever. You would have movie nights and hes let you borrow his sweaters If you wanted and hes get all shy about it. Hed treat you so nice and feel bad about him being an idol sometimes getting in the way for your friendship and hes call you almost every night so you two dont miss a single thing. Or how he'd willingly cuddle you if you wanted because he like to make sure you feel safe with him.
Or Mark from NCT. And how youd have the worlds most soft and loving bestfriend. He'd be by your side as much as he can and can always tell when something is wrong (even over call or text). Since he's always working and barely get time off (fuck you SM) hed probably would have bought you a stuffie/plush and gives you a sweater of his (is it just me or is stealing your bestfriends sweater the best?) And when you call him crying either being you were having a bad night or because you missed him he'd tell you to wear his sweater, if you weren't already, and to cuddle the plush he got you and sleep/nap. Also I feel like he'd give great hugs and would probably cuddle you if you wanted (I want a Mark)
Minho from Stray Kids. Just pure crackhead vibes together. Never a dull moment with him and it will always be like that. Extremely caring but doesn't exactly show it. He'll buy you your favorite snacks/drink and give it to you nonchalantly like its no big deal, but want you enjoy with a slight smile on his face. When you hang out you just chill in comfy clothes and lounge. Probably just watch shows and chill with his cats. Speaking of his cats he probably sends you pics of them all the time. Also one to give great hugs. They feel like home and you always feel safe him his arms
Kevin from The Boyz. Hed probably either be more affectionate or big brother like. Taking care of you and worried about you. Protecting you from others and harsh judgement on any potential partners you may have, only because he wants you to have the best and wont settle for anything less. Will give you his sweaters and say you look cute in them (because you 100% would) and takes a whole bunch of pictures with you all the time. Probably even has a selfie of you guys as his lockscreen or something. Probably has an arm around you when you guys go out, skin ship seems like it'd be a casual thing with him, that is unless you dont want it. Would not hesitate to LEGITIMATELY TACKLE YOU in a hug after a tour or something or just not seeing you after a while. And will definitely invite himself in to your own house on his days off just to come see his bestfriend.
Chanyeol from EXO. He'd be the one to border on annoying and adorable. But it's okay because he likes to treat you as much as possible and would give you the world if possible. Wants to set an example of what kind of person you should be with and that you shouldn't settle for anything less. Will say you look beautiful/handsome/good looking/pretty/cute and does expect you to say he looks handsome too and gets all shy when you call him a adorable and cute. His hugs... omg the best. Since hes is tall he just traps you and hold you and will 100% give cuddles if wanted. Takes you with him to make music and has had you in the recording booth while he records so he can show off his skills. You steal his sweaters and he jokingly complains but actually doesnt really mind.
Idk I feel like there are more idols that would be great to be bestfriends with but these are the ones that came to mind first :)
