I just thought of something funny for your streamer au.
I know people are able to live stream on YouTube (or wherever Pure Vanilla is at), and I imagine that Pure Vanilla does a stream once in a blue moon. Whenever he does stream it is either him tending to his plants, or playing some type of farming or animal crossing type game (but that rarely happens).
Whenever Pure Vanilla does decide to stream, I can just see Shadow Milk just dropping anything to immediately watch. Does not matter if he is hanging with someone or streaming at that moment, he is like “ALRIGHT SHOWS OVER, GOT TO GO!!” And just books it to his bed. No one knows he does it, not even the other beasts streamers (though he can rarely get out of ending the stream early when he streams with them. That causes him to act like a person who just lose their lover at sea). Everyone is trying to figure out and theorize why he randomly does it, (except for perhaps Black Sapphire and Candy Apple) there is even someone posting their theories or ideas on it like that meme ‘I don’t need sleep I need answers!’ Meanwhile Shadow Milk is just vibing, Pure Vanilla is streaming and just read his donation! He can die happy now!
Sorry if this is too long.
YESSSS YES. YES i think pv does those yt stream too! maybe like 1-3 times bc the kids asked him to but still... also the animal crossing idea is so nice i totally believe it! and yes smilk drops EVERYTHING and glues to his screen
