You can watch the entire series in 1hr so there isn't much time to develop characters and relationships.
I wish it was longer because despite everything being rushed I still enjoyed it, so I just wish they had a better time to establish they world, the magic in it, the backgrounds of the characters, relationships and friendships. I think they did what they could with the time but they still needed more space to develop.
However, I still recommend it. It's short, cute, fast paced but not forced.
And Its pretty gay for a chinesse series, If I didn't already knew about the censorship in China this series definitely would not make me think there is any.
