A simple story of the awkward princess becoming betrothed to a prince and the trials and tribulations that happen as a result. It leans into politics a bit however it isn't a fantasy story. Which is what I liked about it. No other world main hero, no magical chosen one powers. Just a simple story about a princess to be that actually READS and learns and uses that to solve problems. The greatest drawback of this anime is how abbreviated things are from the books. There's a lot cut out about her reading about stuff and knowing things. It just seems she pulls it out ofthin air when that's not the case.
I also like the touch where the king isn't some old dude with a beard, but is actually around the same age of the queen.

Overall if you want a shoujo/josei series that isn't super action packed and is more iyashikei, this is a good one to watch. Also has a lot of pretty boys as supporting cast.
