It feels like it's a continuation of some story, rather than something new. It felt like I was expected to know these characters already, but I was not aware of them at all. Is this continuation of the novels, instead of adaptation? Or is this intentional for the sake of establishing a long and deep relationship between the characters? Otherwise looks nice, but the "mystery" felt a bit... Forced. I get it, deduction and all that stuff, I am familiar with "feelings" that do not seem to be based on anything, since I am tech support, but this felt just quite groundless.
It also did not resolve anything really. Nothing changed for any of the characters after the "mystery" was "solved". Not for the main characters, not for the side characters. The solution did not seem to have any purpose. Again, maybe this is intentional, since the main characters want to be "ordinary", but it still feels off to me. Will see how it goes in next episode.
