steddie being Platonic Besties. steve gets it in his head that he needs to learn how to braid hair for his next gf and eddie is clearly the perfect model for him to practice on (steve refuses to admit that he just wants an excuse to touch those pretty pretty curls that he can't stop noticing lately). eddie, who's been secretly in love with his straight boy best friend for ages now, is suddenly in a whirlwind of heaven-hell where everytime they hang out, eddie ends up sitting on the floor in between steve's legs while steve plays with his hair. it only takes a couple attempts before "learning to braid hair" turns into massaging eddie's head and playing with his curls and steve gently scratching his short nails along eddie's scalp. eddie manages it for a few weeks until one night he's had one too many beers and a couple too many tokes and finds himself melting into steve and moaning softly as the man pets his hair. he doesn't even realize he's pitching a tent until steve laughs, soft and equally as cross-faded, and mumbles "want me to take care of that too after i'm done with your hair?"

dustin nearly calls an emergency meeting because he thinks there's a new monster after seeing steve's arms covered in bite marks. cue very awkward conversation where steve has to explain that those are from eddie's teeth and he actually really likes them thanks

dustin uses the bathroom at steve's place and is convinced that steve has a secret gf because there's twice as many hairspray cans under the sneak (he's not snooping, the drawer just slipped open!) and there's a long curly hairs in the shower and is that eyeliner in the medicine cabinet???

eddie's the type to get jealous of a cat. steve adopts a ratty little stray and and eddie immediately hates it because it's stealing all of steve's cuddles. eddie will hear steve babytalking and look up thinking it's for him, only to see his bf sweet-talking another man (cat). when steve is gone, eddie and the cat both get lonely so they end up in the same room. they start out on opposite ends of the room, then slowly inch closer and closer until eventually steve comes home to find his bf passed out on the couch with a cat on his chest. (also, steve only adopted the cat bc he saw its messy fur and scarred little ears from living on the streets and it reminded him of eddie)

i am soo fond of a steve harrington that used to regularly make out with his male friends and jerk off together. he just thinks it's Normal Guy Stuff and so it takes him ages to realize he's bi. even when he stares at eddie's mouth and wonders about what his dick looks like, steve thinks it's all just a typical part of being friends. he thinks eddie is the closest male friend he's ever had so of course the feelings are stronger than they were before!

eddie sneezes a big loud shake-the-house sneeze and steve makes a bunch of tiny kitten noises. steve thinks eddie's sneeze is adorable and, while everyone else is grabbing their seats and looking over to look for the explosion that just went off, steve is looking over with hearts in his eyes and cooing over that sweet baby cutie pie angel sneeze

fairy steve x werewolf eddie except steve has vicious little fangs that can rip your neck out and razor sharp wings that slice through skin and bone with ease, and eddie coughs up hairballs sometimes and he blissfully kicks his foot when u rub his tummy

steve and eddie go christmas carolling together and steve is earnestly charming the suburban moms while eddie stands right next to him screaming out a metal version of jingle bells

steddie au where eddie thinks they're just hooking up because steve never treats him like all his previous girlfriends, but steve thinks they're dating and the relationship is only different because it's Gay. he's just trying to follow eddie's lead without making a fool of himself (he keeps buying gifts and flowers then shoving them into the back of his closet because he doesn't want eddie to think he's "treating him like a girl")

in my mind it's simply canon that eddie munson is an objectively bad kisser but steve absolutely loves it

my fav steddie dynamic is when eddie thinks his kinks are way too extreme & embarrassing but then steve is 100x kinkier

nothing is more important to me than steve who keeps accidentally age regressing and eddie who notices and looks after him
