Understandable, and I think 'mundane' is the popular way to describe these type of AUs. It is hard for a plot to really take off in certain situations, outside of relationship drama. I think that is why some of these tropes can't be made into a long fic. Even coffeeshop AUs have some sort of spy/extra plot when they get longer, which is the only way I can read the lengthy ones.
