Now that I've had more time to think on it, I'm not a fan of this - it feels like one of those stories where all of the antagonists have contrived idiocy for the plot to move forward. They all have to miss a lot, between the father not finding it unusual that someone went from acting feral to acting in high society overnight, to the prince being offended that he's been given permission to have concubines, to nobody important knowing what the prince of their ruling empire looks like. (And a study abroad that lasts for from early childhood to marriage age, which consists of pretending to be someone's slave? Seriously?)
It's got a few neat things going for it - the female lead is solid enough, and the bones of an interesting story are there, but there's a bit too much 'nod and just accept it' for me to handle, and I can handle a reasonable amount of it.
My ratings on the series, from best to worst (with lines between 'enjoyed', 'neutral', and 'disliked'):
1-2, 7-3, 2-3, 2-4, 6-4, 4-5, 5-2, 6-1, 2-2, 4-1, 5-5, 2-1, 1-4, 7-2, 3-2 | 4-4, 6-6, 7-4, 6-5, 7-1, 4-3, 4-2, 3-1, 6-3, 5-1, 4-6, 2-6, 5-4, 1-5, 3-3, 8-1 | 7-5, 3-4, 1-3, 2-5, 3-5, 5-3, 6-2, 1-1
