Have you ever seen the Martian? Did you enjoy just watching Matt Damon use his brains to solve a bunch of different problems? Then this manga might be for you, because it's very similar, though it focuses more on social and political issues, such as political marriages, economics, and dealing with tyrants, rather than technology or survival.

As a standard Isekai, it's nothing amazing. There's drama, some suspense, enjoyable characters, but there's also a lot of talking/exposition about what to do in the political battleground that might leave you a bit bored if you're not interested in that stuff.

That said, I enjoyed it. I laughed, I cared about the characters, the art is good, and most of the decisions/solutions I could follow and made sense.
