It is a very beautiful anime and the thing I found the most interesting was the storytelling. Side characters are interesting and are displayed repeatedly and developed really well. The way they showed the timeskip and still fill the empty holes of past was really interesting. I would recommend watching it as a third person and linking things as that would be really interesting and u will begin to know more about author's perspective of different human values and don't give it a first person perspective as I know many ppl who quit the anime at the first episode just because it didn't match their edgy mc perspective.
Another thing I found interesting is that the episode gets you thinking and linking the plot points which makes the story even better. Not to say that the opening and ending songs are really good and I love them.
