Yeah I see people shitting on the characters ever chapter but IMO they're very well written characters that have issues and trauma... Everything about this series has been great other then the execution of it at points
Again we are not the French and of you have your word processor or browser set to the right language instead of French. The origins of your "rules" are someone's opinion piece on how English should be written (more similar to Latin and purposely obtuse to sound "elegant") and not actually rules...
The accents on fiance are in fact optional and in fact usually recommended to not be used in modern style guides (as English doesn't actually use accent marks and the marks are a French thing). Being pretentious and making up fake grammar rules helps no one
There's a few typos like on page 7 it should be "what did you you say" instead "what did you said" and on 23 is should be "are his tools" instead of "is his tool"
