Let's start well ...
They clearly missed parts during the creation of this manga, like the one in which he convinces his father to do those things to improve the harvest.
Even if I haven't read the novel I can't imagine how many other parts will jump, I would have preferred that at least the beginning explained it calmly.
The story had potential to be like a Duke's Daughter in regards to management of a territory and world building, but this pacing is horrible even for a first chapter. It feels way too fast and drama coming in already before establishing a backstory for the new world is really throwing me off.
