The story loses its charm somewhat after 4th episode and again after 11 episode.you keep thinking or waiting some big event to happen but nothing happens. In the beginning it is showed as butterflies might be a big deal Thts why both brothers keep moving but turns out it was not that big deal.Also the story between Kang tae and Ko moon is also not soo exciting.It just seems pretty obvious what will happen next. Nothing to keep the audience on their toes and make them jump with excitement. Trill and excitement is what is missing in its okay not to be okay besides that story is also not very strong .there reasons aren’t that strong.
