In my view, Korean dramas are very predictable once you figured out the core pattern they usually employ for Kdrama, which are usually repeated in many other Kdramas. Note that there are a couple of elements or core pattern that they usually use to write the drama and some are just permutation of that core pattern but still be recognizable once you get used to watching kdramas. It's usually easy to have an idea how the drama will turn out from the very beginning because of that core pattern they use plus there are only a couple of episodes usually in the range of 16 episodes to 21 episodes, which confined the storyline and the core pattern easily recognizable if you have figured it out. I should point out that even though Kdramas can be figured out and predicted, the creativity of kdrama writers and their utilization of good story telling technique and good directing which complement the storyline makes kdrama very interesting to watch.
