Autistic girl in a world not aware of autism. Or, at least, it looks like that may be the case: people with ASD often are bad at presenting emotions, and can have high affinity to things, especially when forced to mask. Especially, when people around are total dicks. I get it, that when you expect someone to smile, and they don't it may feel uncomfortable or disheartening, especially for people who expect everyone to react to things the same way they do, but this felt a bit extreme.
Otherwise... It's kind of plain, and I think I know already, what will be happening here. The girl is moved from a hateful environment to the one, where she is appreciated, and does not need to work too hard, and is not even expected to smile. She will, obviously, fall in love with the prince of this new nation, and through silly interactions, she will start feeling emotions, and the series will end with her smiling for the first time. Or at least smiling widely, because small smiles probably will happen earlier than that.
Looks kind of cute, I guess, but in this setting no one can top in the emotionlessness Yumiella Dolkness for me, so gonna skip this one. Even though the girls is voiced by Mikasa Ackerman.
