Lord of Another World: Starting as a Live-In Son-in-Law

Does the concept of "marrying into another's family" exist in the West? Back then, didn't people just take advantage of widows who had no descendants? For example, after marrying a widow, they might secretly kill her.

For example, is it appropriate for the grandson of a provincial governor to marry the widow of a village chief?

Starting with the protagonist's resourcefulness and having a loyal, ten-man armed caravan is standard practice.

... That nominal father-in-law was disgusting. Did the author forget that the protagonist comes from a noble family? Just call in a top expert from the family, find an opportunity to kill this scoundrel on the grounds of insulting the family honor—that would be perfectly reasonable, considering he's a commoner.

It has the ability to use magic, possesses a cheat-like ability to manipulate things, and still manages to turn it into a street fight.

Acquiring territory is incredibly tough. Mads Mikkelsen has a movie about it, and after watching it, I was speechless. It's so arduous, comparable to digging potatoes in Siberia. So don't ask why the protagonist would rather marry into another family than conquer territory himself.

It's a bit slow to heat up, has no major flaws, but also lacks any particularly appealing highlights; it's rather bland.

I don't understand. The protagonist earned 7,000 gold coins in five years of schooling in the capital, far more than the income from this territory. And this is a world with extraordinary abilities. Shouldn't he be using that money to improve his strength? Why is he stuck in a small, rural territory, feeling so stifled? Doesn't strength equal noble lands?

I've voted for the author with a monthly pass. Will the author still be able to continue?

The romance scenes were so awkwardly written. 😥
