I've been a bookworm forever. Before the net became big, I was the one checking out library books to the upper limit. My only requirement was "does it look interesting." Since the net became big, I continue reading what looks interesting that comes across my path.
So I've picked up a lot of bits and pieces of knowledge over the years, but unless it was in the last few years, I can't say where specifically I might have gotten a factoid.
I do know manga like this tends to blend bits of European cultural etiquette with cultural etiquette from the country of origin. Nobility in both European and Asian cultures tends to have rules that you don't approach the ladies of the family, especially a man approaching the unmarried daughters, unless you are reallllly good friends of the family or at a formal event, and it goes double for just before a formal event, for whatever reason.
