This is one well created piece of work,and from its quality,quite an amount of time and effort has been put into it,so this really deserves a high score and position,and kudos to the creator for making this.The change in the setting from the moment a seemingly innocent wish was made by the protanogist,thinking it was for a better future to the point when he ends up fighting and sacrificing everything for his love just goes to show that true love is a powerful force and that appearances and disabilities do not matter.Here is a little poem to describe the message in the animation:
For these two,they share a loving heart,
Nothing would ever break them apart.
So yeah,everything is well done here,from the black and white concept,the original animation style(looks that way),the plot,the soundtracks which suit the tone of the story and the voice if there was any.
(Note:The plot of the story feels like 'The Monkey's Paw' by W.W Jacobs as in the story,the protanogist wished for something good and ended up with dealing with the result,except that this has a happier ending to it.)
