Its one of the best k dramas i have watched so far, the story starts off slow and quite confusing. The main characters don't out much and there are a lots of part which are hard to watch you get connected with the characters. But as the story progresses the series changes a lot from what it was at start. The characters accept their fears, and try fighting it, they learn a lot too. The after episode 8 is like a roller-coaster ride, way too many things happen and you will not be able to skip the parts at all because you will be glued to the scene trying to keenly watch everything and absorbing & enjoying them. Its worth the watch so bear with it at start and trust me at the end you won't regret watching it.
