It's a good anime, I only wished that they put extra depth in the story. It was so good in terms of animation and music, and the characters were okay, but the story just seemed to me like it had a lot of gaps. That it seemed too fast, in a way that moments (happy, sad & difficult) seemed like they didn't have time to stay in the spotlight. Also, I would've liked to know more about the story in the eyes of the other characters. But, other than those, it was an okay romance-scifi-dystopian-shounen anime.
