Domlaurie is harder to pin down, I read them more as having a friends with benefits situation rather than a romantic one
Their relationship starts when Dom happens to find Laurie on Grindr, Laurie has one of those accounts that don't have any face pics, Dom sends him a few messages before releasing he recognises Laurie's tattoos and is thoroughly embarrassed that Laurie had to find out he was into him on fucking Grindr of all places but Laurie plays it cool and they hit it off from there
As a fwb situation I think their relationship is very equal, if they play with power dynamic both of them play both sides though with Dom leaning more dominant
They're very physically affectionate, they minimize it for the camera but they both like to take whatever excuse they can to touch each other
Laurie usually doesn't get great sleep but he sleeps a lot better when he's cuddling Dom, Dom snores a bit but Laurie finds it comforting
