Adrian, thank you for your Morales 
But to be honest with you, just these shower scenes made me realize how different the Asian entertainment industry is in comparison to the West.
I guess it is simply the rule of Demand and Supply.
Western female stars have to reveal their flesh, because male fans are willing to pay for it. In the Asian world it is the other way around. All those hard working girls like to sigh over their Oppa’s on stage, and on screen, while Asian guys prefer to play a computer game.
So, all in all, I believe there is already a standard for what is done and shown, called The Gold Standard
