I think this is the beggining of the new are of anime. I've watched many Japanese anime over the time. This was the whole new experience. I want to see season 2 and furthermore more good anime like this from Chinese anime industry. Just start watching. When you've ended, you will want to watch it again to feel the feelings again. Opening and Ending music are absolutely cool that you will want to hear time to time. Characters are so cool that you will want to imitate. Story is new, realistic and deep that you have never felt it before.
