Didn't like this part 2, it felt like the show dragged. It could have been condensed in one season of 12 episodes, at most. I really liked Im Ji Yeon's acting though.
The number of native Koreans that are either Jews or Muslims in SK is basically null, Christianity on the other hand gathers the most religious people there. Besides, the whole point of the scene was using the religious rites that made the scene possible, Buddhism doesn't have a similar structure as Christianity. Stop malding over a dramatisation, it isn't even real.
