I had an existential crisis when i tried to think too hard about the themes of this work. it's beautiful. I will say that i think the age of this work works a lot against it but the fact that a remake exists gives me a lot of hope through that it can live up to its full potential. While in many ways it is the same scenario as subahibi (more accurately, subahibi is a reimagining of the tsui no sora scenario) I found the overall themes to be much more profound and consistent in this one and I enjoyed that a lot. (I will say that subahibi is better in many other ways and is overall the better of the two).
