Jeongin doesn't enjoy physical affection, especially when it's forced on him, much like how his friends do it.
He thinks cuddling looks stuffy, though he's never actually properly cuddled before, mostly he has just been momentarily suffocated by Hyunjin.
Constantly his older friends feel the need to touch him, surprising him with hugs, poking his cheeks, grabbing his hands, and even smacking his butt. That last one is mostly Seungmin, he seems to have an obsession.
But aside from Seungmin and his odd obsession, and Hyunjin and his quick suffocating attacks, Chan is the one who seems to seek physical affection from him the most.
