Interesting to me is the comparison between the harem in this and the WN. In the WN,
it's only Haruvatat and Carol. There's quite a bit of fanservice with all the other girls. It's usually the other way around. The WN shenanigans get toned down for the LN or Manga versions.
I do really like that they kept the bit where Carol meets her Dad's friend. It's a really nice waypoint in her journey from 'My family died, and now I should die too' to 'I'm a talented, useful person who has love and belonging.' A lot of the characters in the story get surprisingly good character arcs, and did, even in the WN.
