ah hard to say, im a person who loves canon LMAO, so the only aus i really vibe with are the modern aus (but not when one of them is a florist or a barista. i always imagine them having jobs that actually fit their strengths, and i dont find those coffeeshop aus interesting)

one au (or more like scenario) id love to see them more in is any interactions with aranara. i love the aranara and i think hkvh would be surrounded by them
