A lot of people recommended this manga and although it's not edgy which is a welcome change, it's even less realistic than those.
First of all, how did such a guy become king let alone stay in that position.
The guards showing emotions is also plain stupid and doesn't show the king being good bit rather their commander being an idiot. Really they're supposed to be the royal guards, the top of the top.
Really, normally this wouldn't botter me this much, but I was anticipating a "realistic" scenario after being summoned to such a world because the title and good reviews. What a lettdown, it seems a prerequisite for writing isekai is having brains of a 14year old.
