fuck i wanna talk about all my ak bastards so this is going to be long
lazuli expressions affection very autisticly, usually via parallel play, but for more romantic affection they're very tactile, if they could have their hands on their partner, they are CERTAINLY touching them some how, usually prodding and just [grab]
zoloft- gift giving, both platonically or romantically
salem- also a more tactile person, everyone he likes gets hugs
backcountry- he is doge and he expresses affection like a doge, lots of tail wagging, very verbally and lots of hugs "hi!!!!! hi!!!! i love you!!!" energy
codeBLUE- romantically she'll offer to take them out for a drink, also uses a lot of petnames casually, for platonic she is just a lot... softer with them, more gentle
cyanide- really a "acts of service" kind of guy, he won't say "i love you" too often, but he will do your laundry without you even asking first. platonically he offers first
salem- everyone he loves, no matter how, is going to get a hug
i dont know if viridis can genuinely like anyone
