Let's say the old king has son at the age of 20. So if his son is 20 then he should be 40. If yui is 15 then... there should be 25 years gap. That old king, tho he is handsome, hot and has a cool goaty, he is still old...

The old king likely had a son at the age of him going thru puberty and this could be anywhere from 12 to 15 years old. This was often common in the old ages. So yes it is a fact that in ancient times that a 30 year old man would be married to a 15 year old girl. This doesn't mean its not nasty for which I think it is. Yet if you want a historical story this is how history truly was. Keep in mind in some countries even today that follow some practices they men can marry a 9 year old girl. Its sick but it still happens in many middle eastern countries today.

That train plan!!! I disagree! What use of contributing to the territory only to feed greedy wolves. MC is a pushover. Too kind that it's a bit silly. Forget it. Maybe coz I'm not a good person. So, I can't understand this selfless sacrifice lol

From modern people perspective, it sure is seems like that.
But, it alway like that if we learn about history.
Train in the past is always reserve for upper class citizen. Because frankly, normal people can't pay the operational fee.
But from there, it will be changes and innovation for people in the middle class. And then from lower class income.
But, even then there's still people who can't afford that.
Yes, it sucks if the one who build it can't even use it, but that's why he struck a deal with the duke.
Too many POV... Not that i hate it, just not too engaging
