Agreeing with Matilda here too, taxes doesn't mean a damn thing if you waste manpower to pursue it and end up losing a war and having your country destroyed. An older guy like that shouldn't have to be told that but a young sub ruler.
Nah, the old man has a valid concern. The location is both a major source of resupply and the staging area for the coming invasion of the demon nation. Their navy spent considerable resources in subduing the islands and frankly should have a rather heavy presence to ensure it stays under their control.
But as this is a manga that doesn't require deep thought, many of the realities of functional governmental and war time practices are ignored because it is beyond the author's ability understand let alone properly portray.
You honestly need no further example then how the invasion of the islands was described. Half the population was slaughtered, their supplies were pillaged, and the survivors were all but enslaved. Yet in complete contrast their virgin queen is happily getting married and living the SoL dream with the isekai MC.
Logic means little when confronted with manga logic.
Hate the "and then the next day" bait, lol they even woke up fully dressed, nothing out of order. Artist or publisher must be uncomfortable at least drawing a nude body.
no argument with the fully dressed characters being strange, but I'm sure the near complete lack of anything more risque then hand holding is likely restricted due to the target audience.
