We all know that in Kdramaland the writers/producers/kdrama gods really love a good trend. Love it enough that they saturate our tv's with a concept so thoroughly, that if we hear the word Noona Romance one more time, we involuntarily cringe. So why do they feel the need to jump on a concept bandwagon? Are they afraid that if they wait 6 mths that everyone will forget that they enjoy multiple personality dramas?
