Got best actors, best story but finally they all depends on is serious characters acting stupid(cute-my a**).
They didn't stick true to their characters. At least they maintained suspense.
Acting was good, direction and screenplay must appreciate them.
At end, they show that South Koreans are good even to North Koreans who invaded into their country(Like they do..pfff)
If you have already watched GOBLIN, BOF, The Heirs, Love From Another Star, etc...these kind romantic dramas. Better skip it.
