I agree with Kawther (go read their review), the person which said that the characters in this show is sexualised, that a small bit of romance, a bit of harm and seemingly "perfect body types" will harm children is just plain stupid. Please, this show is appropriate and many other shows have inappropriate moments added in for the adults yet I don't see people complaining about that.
Please give this series a try as it's very original and is a good watch. I've been watching it since I was 13 and I wish I found it sooner.
