This isn't a perfect adaptation of the light novel, but it's miles better than the movie. Character designs are a bit questionable at times, especially for more close up shots, but it doesn't impact the reading experience much. I do think there was a lot more comedy added compared to the light novel, which kinda makes the emotional scenes less emotional. The characters do feel pretty similar to their ln counterparts, and are actually expressive, unlike in the movie. Just don't watch the movie. I beg of you 🙏
Overall is a good adaptation and definitely worth the read if lns aren't your thing. If you're fine with reading books then go read the light novel instead
