while i would like to say that i watched it when it came out it took netflix to find this hidden jem. the story is really good and fast pace. there is no episodes that are throw aways which is really good because there are not a lot of them. it a really good story with a great music with a debut from jyp korean group into japan as the opener you may of heard of them.
