@KaelRhain:
Hunting was a common leisure sport for the nobility, yes.
However, a specific plotline based around a (usually annual or less frequent) grand hunting competition, with a lot of honour placed on winning and often more political intrigue than seems likely for a leisure sport or competition (even amongst the nobility), generally with girls giving charms to the men they favour and/or the winning man gracing one favoured woman of his choice a the end—it's recycling
that plot device, not the general omnipresence of competitive hunting
per se, that what I was being arch about.
I'm not even particularly upset about it or anything, just felt when I was writing it that it was at risk of becoming the sort of fantasy-shoujo-manwha equivalent of, say, the inescapable onsen or beach episodes in more traditional romcom manga, except perhaps even further divorced from reality.
