Amazing! In one word
This drama is blended with freshness of Nature´s beauty and beautiful Love story of two individual personalities.
I agree that the drama story progression is little bit slow compared to other K-Dramas but the more you gradually watch the episodes, the more you can feel the intensity of the whole story, situation & incidents of the lead characters.
Otherwise, it is 100% worth to spend some of your moments of life and feel the drama! It is Unique from the location and story plot.
