it is truly insane the various roles/dynamics/functions/molds they have fulfilled throughout their relationship:
domineering older brother (noel) and annoying little brother (liam)
biblical sufferer (noel) and the heaven-sent angel that saved him (liam)
Guy Trying to Do the Right Thing (noel) and the sexy devil (liam) relentlessly on his heels trying to lure him into sin
boss (noel) and employee (liam)
pimp (noel) and his top earner (liam)
father (noel) and son (liam)
daddy (noel) and kitten (liam)
artist (noel) and muse (liam)
writer (noel) and his tragically uncontrollable manic pixie dream girl (liam)
its a bit of a tasteless comparison but beauty (liam) and the beast (noel), at least in noel's eyes (but it's important to note that the way noel covets liam's beauty is very layered. he's proud to have such a beautiful man obsessed with him and he gets a lot of pleasure in appreciating liam's beauty but he's still jealous of the effect his brother has on people).
uncles to each other's children
huge 180, now it's macho butch boyfriend (liam) and his petite helpless girlfriend (noel)
^ hunter (liam) and prey (noel)
owner (noel) and dog (liam) (or cat/dog)
dom (noel) and his bitch (liam)
'big' brother (liam) and 'little' brother (noel) *we agree that this is straight up just a sex thing right?
bully (both) and bullied (both)
lovesick fool (both) and the heartbreaker (both)
literally the same entity (LiamNoel)
polyamorous life partners
and they've sexualized all of these! :)
