I want you guys to know that in my bloodymary teachers au, despite the lack of near death experiences and being alone in space, Grace, Rocky and Adrian are STILL equally weird and codependent.
Like Simon rocks up one day, having very little experience with friendship or relationship (because of reasons I will explain later) and witnesses the insane dynamic of this married couple who are deeply in love and their weird friend who just kind of is there and who they love a lot but don't have romantic/sexual feelings for. Grace who lived with Rocky for years prior to the marriage while Rocky and Adrian were long distance, and didn't move out until well into their marriage when he decided he wanted his own space. Like Rocky and Adrian didn't actually have a particularly strong desire for him to move out it just kind of happened, and even then he lives down the road and comes round all the time for games night and movie night. Grace who talks about Adrian with as much, if not more reverence than Rocky. Rocky who brings in a packed lunch for Grace from Adrian some days because they know grace is stupid and forgets to eat.
Like to the point where, before Simon meets/knows about Adrian, he assumes that Grace and Rocky have some kind of weird will-they-won't-they arrangement (which he's trying not to get too disappointed about) and figures that's why grace is content with being, quote-unquote, "single". Until he finds out that Rocky is married and so in love with Adrian that nothing could change that, and the three of them are actually just really fucking strange in a way that nobody can fully understand.
It's really just "this is my husband Rocky. and this is Rocky's weird codependent queerplatonic best friend/coworker/work husband Grace. They come as a package deal, and I love them very much"
