Overall: 7.33/10 (arguably 8/10 if rated for its sum rather than both the sum and its parts, how one views and scores the animation and story will determine their overall score)
Story: 6/10 (It really is simple. Too simple for what is actually shown and has little/no potential for what the plot offer. At the same time, there no major faults and nothing can be done to improve it. It's just fine the way it is. So, in the end, because it is focused more on the story and art than the characters, it is just fine.)
Character: 6/10 (certainly there is character development and catharsis but the side cast can be cast aside and the main male protagonist is in a drug-induced state of love. It is just about the two main protagonists. At least, there are some twists. The development is quite predictable because it is partially about love.)
Art: 10/10 (Unquestionably perfect)
Sound: 9/10 (I'm not convinced with the ED and the voice acting of others, most of it is perfect for sure but not necessarily memorable)
Value: 6/10 (certainly memorable as a whole and worth re-watching (if one wants to understand), certainly one of the best short anime oav ever made but ... not a masterpiece and a classic; it's a niche pick recommended for those who love art/literature)
Enjoyment: 7/10 (Too pretentious for me to love it but certainly caught my attention since hearing the main theme and never lost it (until it ended ofc))
