JK Haru wa Isekai de Shoufu ni Natta
This doesnt have any nobles but it's technically historical since its isekai. This is a good read alone, without the smut. Our mc isekais with her classmate to a typical fantasy world, she becomes a sex worker and experiences the new world that was (mostly) built for men. I suggest reading this for plot and not the smut This surprised me cos its really deep and has an underlying theme and message to the story 5/5
