Finally finished watching this drama and will happily move on to the next.
In the end this drama did make me take notice of Shori's improvement as an actor and I have come to see Yasui as a Junior that genuinely interests me. So this was hardly a complete loss. And even then it was not a terrible drama, just not a great one, which still places it above at least a couple of other drama series from the NTV late night line up I have already watched. It just tried to do far too much without doing the right build up for it and should have kept things simpler.
With that though I am more than willing to move on and start up a new drama series.
