ok i presume this means going thru the individual pairings so i'll approach it like that, feel free to come back and correct me;

tighnari/haitham: had to start with my personal guilty pleasure. many think kaveh & haitham ones to butt heads intellectually, but the real wit sparks when tighnari enters the room. it's explosive, almost bordering hate sex if they weren't so enamored with each other. haitham is such a tease and tighnari fights for control, it's a wonder nari doesn't end up biting his dick off-- but later when his cheek is pressed into the mattress and utterly wrecked, maybe he'll call it even. love them.

tighnari/cyno: insta classic, have always loved them. like classic lovers, deepened by the intimacy that comes with best-friendship. i like to think they're smitten with each other and very handsy, pinkies entwined always for the closest connection in the smallest ways. dictionary definition of understanding. lovemakers!!! yet still kinky ofc.

tighnari/kaveh: UNDERESTIMATED KINGS; their teasing is off the charts. not trying to infuriate each other, so familiar in friendship in a similar way to nari/cyno but this time with a 'ur so hot i always wanna kiss you' kind of way. even in friendship i see them being very queerplatonic; but as 4gg lovers, dial it up by 900%. always making out in the corner of lambad's, tighnari teasing little moans out of kaveh when he's feeling a tad more sadistic than usual. LOVE THEM

kaveh/cyno: underrated, understated. playing footsie while kaveh gets his ass handed to him in TCG. a caring sort of, /'be safe', 'i will'/ dynamic after starting to connect more. cyno gradually becomes softer and more unguarded around kaveh, and kaveh waits with saintly patience until finally they can spend hours cuddling, kissing, sleeping together... so soft :'((( LOVE THEM

kaveh/haitham: WHO CAN KILL THIS CLASSIC? NOBODY!!!!! please understand why i write them so often. the yearning. the familiarity. stolen glances at the man you've come to love but once fell completely apart to. hearts broken in friendship, reforged as lovers-- and in 4gg they'll be so much softer in the end, arguably the most passionate lovemakers and most bleeding of hearts in shared affection. i could imagine the 4gg boys starting to catch feelings all around, and tighnari & cyno thinking they have no chance with these two already so deeply entrenched in each others' lives. MY BOYS!

haitham/cyno: honestly my first thought was, they must've gotten SO horny after fighting each other in the desert LOL. physical fights for dominance in these kings. a new-age rivalry for alhaitham, where intellect bows out and a sort of feral instinct rises between these two. love them, can see them taking a long time to become 'affectionate' but some day it'll click and they'll kiss each other goodbye, haitham huffing in amusement and cyno covering an embarrassed pout.

bonus: triads

alhaitham/tighnari/cyno: basically, alhaitham and tighnari in a tiff about who gets to tug on cyno's leash. love them.

alhaitham/kaveh/cyno: the world's sexiest sandwich, kaveh can't get away without warring possessive marks on his neck-- or sometimes the script flipping with cyno the one being marked.

alhaitham/kaveh/tighnari: DROOLS SLOBBERS BARKBARKBARK RRRRR RUFF RUFF BARKBARK the kinkiest sweatiest double-penetrationiest snarkiest-- and the times when kaveh gets the deepest in subspace.

kaveh/cyno/tighnari: soft whispers under bedsheets. sweet hands between thighs. hushed praise, light tugs of hair, the most 'i love you's that can be said. love them.
