It seems that The Last Empress starring Jang Na Ra, Shin Sung Rok, and Choi Jin Hyuk is getting an extension! It has had quite a successful run, so it really is no surprise they would want to extend that. This will bring the dramas total to 52 of the short episodes.
The Last Empress is set in a fictional South Korea which operates under a constitutional monarchy. It follows a musical actress (Jang Na Ra) who marries the emperor (Shin Sung Rok) and becomes involved in the palace power struggle and a mysterious murder.
The Last Empress airs Wednesday and Thursday on SBS.
