You have so many to choose from, but your plan to watch list has so many good things! First, my favorite drama ever, Bridal Mask, so I have to recommend that before anything else.
My favorites of the rest (of the ones I've finished): White Christmas, Missing Noir M, Bad Guys and God's Quiz.
And Nodame Cantabile, even though that's completely different from the others I've recommended. I can totally recommend all of those dramas. If your taste is like mine, haha.
