I feel lots of Kota/Naoya vibes in here :) Yanase has the same cute smile as Naoya while I feel Kota's kinda double personality and his facial expressions when I look at Kaneda.

Enchanté has a deep connection with France throughout the show. Semantic Error only has a little connection. Probably this is the only similarity between the two, apart from the college setting.
If you feel in a certain way for Book's connection with France in the final episodes, you'll be delighted with how Semantic Error's characters deal with the France issues.
