Most of the audience has written negative reviews, I respect all of them.
But to be honest, I can understand this response as this is an Anime with a very Abstract theme. It's very specific and designed to align with a realistic point of view and emotions.
To understand anime we need to really think from the viewpoint of MCs. Touko and Kakeru are both very complicated characters in a very complicated situations and how they deal with their circumstances forms the crux of the story.
Once you relate to the story it really hits the mark and you realize how beautifully its been thought. A very Unique and Different anime that I have come across, It was really delightful.
Kakeru and Touko both the MCs have great depth and the bond shared by Touko and her friends has also been kept very realistic rather than the very grand bond of unbreakable friendship that is usually the case in classic anime.
If you take a liking to life philosophy and very realistic situation settings with a tint of fantasy, you'll surely understand why I gave it an 8 despite its overall low score and negative reviews.
