if you’re okay with manga recommendations instead of manhwa, i highly recommend innocent/innocent rouge. but if you’re asking for recs about the french revolution you might’ve already read it ^^;
I’m crying all I can think of is hetalia
There is this isekai-which is kind of French themed and set in a world that’s about class revolution (rich vs “commoners”). But it’s not historical—

I personally prefer the anime version tho.
Is there any manhwa that heavily references french and/or american revolution? I need it for research
