Korean Remake: Tell me your perfect ML and FL

Oh I just saw this thread .. what a fun question.

I wish people would elaborate about what they chose the actors they feel would carry off a Kdrama version.
DO make a  pitch your actors for the roles .. 

This thread would heat up more I feel ;-p

In the meantime I'll give this a think too and also see who the suggestions are on this thread .. and if they work for me too ;-p
