I think this series was just a bit too over-hyped for me, which only caused it to fall short. The actors' chemistry couldn't save this series.
The script is quite poor, there are a few well-written scenes in particular between Uea and his stepfather. But besides that, I really don't have much to add to this show.
I found myself losing interest as the episodes went on. If you are looking for a show with a nice story and well-written this is not the one. If you are looking for a show with a lot of NC scenes and great chemistry between the actors this is the show for you.
