I can tell this is gonna be good...

I really actually love the idea that they killed off the band leader ( great actor fell in love with his character and wish he didn't die but glad he did) Only because when something like this happens in a show, it is hard to pull off but it usually ends up being extremely awesome and very well written. The writers wanted the audience to be captured by the main leader because if we all knew the personality of the other characters really well in the first 2 eps, the drama would end up being boring until the end. This adds suspense for the drama and the chance to develop the other characters.
