Revisiting this and I feel exactly how I felt a year ago. This was so much better when she was just going around discovering this new world, making friends, making herself helpful, going shopping, etc. It took an immediate nosedive with the formal introduction of the demon king romantic interest and the fated lover plot. A very charming young woman with her own agency, trying her best to navigate life in a new place, immediately turned into some soppy pathetic brainwashed thing.
Ugh. At least there's some closure I guess.
