Best to worst roommate ranking:
Mimi > Yura > Delta = Lucius >>>>>>>>>> Silver
Mimi: Very clean, cooks and cleans without being asked, stocks up on groceries and snacks and always knows what you need HOWEVER he is very secretive so this is only if he was theoretically ever someone's roommate
Yura: Also very tidy when it comes to shared living spaces (her own room can get a bit messy), always does her share of chores, can cook decently
Delta: Cooks REALLY well, holes up in her room sometimes when she's busy working on stuff, very moody and irritable though when he's busy working on said stuff though so fair warning
Lucius: Very clean, cooking is really only passable to survive because they care about nutrients more than taste, really meticulous with where things are supposed to be so they might get annoyed if you move things from where they were to a different place
Silver: Can't cook, is a fucking slob, constantly bringing people (fwbs/hookups) over and having disgusting loud sex at 3am... however he is surprisingly nice and will always pay for things like groceries and snacks and treat people to things constantly. Doesn't really make up for it though
