Masterpiece.Its very beautiful,marvelous anime.I'M 100% SURE YOU WILL CRY AT THE MIDDLE.But don't worry, the ending goes invincible.To be honest ,this story will teach you the relationship between two selves won't be able to disapear even lost the memories.If you are a person who is looking for a good,different anime ,then I admit you this is the best one you can find.I love this anime.Also thank you for reading my review.
