I come bearing, like, ideas and stuff. And the colors are just suggestions, obviously that's specifically your call:
Beryl - They're both the friendly and open minded type, by the looks of it! She's stupid weird and probably likes to entertain talk on his conspiracy theories to the point where neither party is sure if the other is actually taking it seriously? I think they'd get along very well as mutually off-beat, though she can probably handily outweird him.
Joanne - If Adele and Billy are icy Joanne's probably on her friend's side and has the wrong impression about Billy. If they meet at a party she won't have much to say.
Charelle - Party goers! Stoners! Charelle is pretty much all about mindless no-responsibilities fun, and it's always good to know one of the main nexuses of the party in town, right? Charelle actually doesn't really smoke tbh but she'll hang around to get a bit of secondhand high before the music kicks in.
Gyu-ri - He hates people who act snobby and Gyu-ri is a violently aggressive elitist who can't help but neg at others and belittle them for not living up to her ridiculous standards. Also one of Ivy's main gal pals. I doubt this one's any productive, she probably can't stand anything he represents.
Demetri - Old childhood friends who hung out from time to time and remained in contact up through high school? Essentially Demetri gets where Ron is coming from and gives Ron the go ahead to become a kiss ass, because that shit's social survival and all. Ron might not try to associate with Demetri too much in school since his brand's a toxic but it's not so bad, so outside of school they might be cool and hang out and game sometimes? I'm also cool with Demetri being totally abandoned and there being some lost love, but it's probably nothing overly dramatic, Demetri has better shit to care about.
Gyu-ri - She can smell out his awkwardness and doesn't like that he plies his way into her scene with alcohol. There is pretty much no way he can suck up to her since she's fairly impossible and she's also a toxic brand anyways despite being quote-unquote an 'in girl', so he probably doesn't bother.
