idk why but. hcs on msby4 picking each other up. like, physically. I was thinking of them being poly while I came up with it but it could also work platonically
Hinata - he’s so so easy to pick up. it all starts with omi unceremoniously and without a word picking him up from where he’s sitting on the counter (in front of the coffee maker omi wanted to use) and putting him back down on the kitchen table instead. the other two observed this and a light switched on in their heads. now they all pick hinata up a lot. he’s kinda indignant about it, but not truly bothered. he does absolutely everything he can to also pick all of them up at any opportunity to even things out tho.
Bokuto - super loves to pick people up and carry them around, will do it for victory hugs or to carry them home or just because. and really who wouldn’t wanna be carried by bokuto so they generally let him. bokuto also loves to be carried just as much, which is a bit more difficult since he’s quite heavy, but at least hinata and atsumu are frequently up to the challenge, it might make their arms hurt after long hours of volleyball practice, but bokuto’s joyous laughter is so worth it.
Atsumu - he can’t be surprise picked up. if you try, he’ll immediately lodge one leg between yours and twist out of your grasp, possibly sending you face first to the ground. bokuto and hinata had to learn this the hard way. atsumu says it’s some kind of reflex/trauma response from osamu throwing him into the river by their house one too many times as kids (when asked how many times he threw osamu into that river, he won’t give a number, but insists it’s more times than osamu got him). so atsumu only gets carried if he asks for it, which he frequently does because he likes it. He likes carrying the others more tho, he likes showing off how strong he is.
Sakusa - the least enthusiastic despite having started it. will rol his eyes if asked to carry anyone, but will usually do it anyway. tho if his joints feel bad, he’ll only say yes to hinata, which bokuto and atsumu find unfair and hinata feels is a dig at his height (it is). he won’t let himself get carried in public, but he secretly enjoys being carried, and once the other three figure that out, they take whatever chance they get to carry him from room to room in the sharehouse. omi still pretends to be annoyed by it, but literally nobody believes him because his poker face is horrible.
