my personal until dawn pronoun/sexuality headcanons but they accidentally turn into normal headcanons too (coming from a bisexual she/they user please don't burn me)
Ashley: she/her, biromantic asexual | just doesn't feel sexual attraction like everyone else. thought she was weird for it then her friends reassured her once she came out (mike joked around with her a lot because he's like the total opposite)
Chris: he/they, bisexual | this man has definitely experimented with Josh before, you cannot tell me otherwise. also maybe possibly transgender and his friends got together and made him a little care package after his top surgery (he cried. he totally cried.)
Emily: she/her, says she's straight but... mm, idk.... | has drunkenly made out with Jess more than once before but she acts like it never happened (they've all seen it happen at least once)
Jess: she/her, unlabeled because she doesn't need a label to tell her what she is (real) | has also kissed Josh once because he's Just That Kissable (also real) but that's all that happened, he still teases her about it sometimes though
Josh: he/him, pansexual | doesn't rlly have a type, as long as they're nice to him and kinda hot then he might develop a crush. jokingly flirts with everyone and they're all pretty used to it, he and Chris go back and forth for hours sometimes just coming up with the stupidest pet names for each other and everyone else is just like "ohh my god shut up already please shut up.."
Matt: he/him, pansexual | literally does not care if someone uses they/them on him though. also, enjoys giving his friends platonic kisses (mostly Ash on her forehead because they're silly friends) and he also kissed Jess on the forehead as a comforting gesture after the whole incident in the mines. fight me, he's love-shaped
Mike: he/him, bisexual | will jokingly respond to she/her and pretends to be one of the girls when Emily and Jess are gossiping. playfully flirts with everyone in their friend group (like josh) but Matt was tired of it and casually flirted back once (surprising bc he always is like "dude, we both have gfs...") and Mike stuttered so hard he almost choked and then tried to play it cool like nothing happened (everyone saw it happen, michael)
Sam: she/her, also unlabeled | doesn't really like labels that much, just wants to like who she likes. doesn't give a shit about they/them being used on her either. she fr just does not care. definitely used to have a small crush on Josh before everything. she, like Matt, loves giving her friends affection though like a small side hug or bumping shoulders or straight up squishing her cheek against theirs bc it makes them laugh
BONUS because i almost forgot about them..
Hannah: she/her, straight | super loud ally when it comes to pride month, rainbows everywhere. Josh and Beth get embarrassed but they love their sister <3 also she definitely crushed on Matt at one point
Beth: she/they, lesbian | tried to date a guy once, never again. does not understand when Hannah gushes over Mike. may or may not have liked Sam at some point but stayed away because she thought Josh and Sam liked each other and she didn't want to get in the middle of it because she wanted Josh to be happy
note: ignore the fact that they're almost all bisexual, it's because they're really fucking fruity, shhh
