This drama is good. Story is acceptable. The best about this drama is the FL. As is the case of most dramas - the FL usually carries the weight. Or more appropriately, more often than not, saves the day.
In this drama, the ML seems too old. Yes, its a mature drama and the roles (member of parliaments) are usually that of middle aged persons. However, there seems to be a mismatch between a super pretty FL and a too old looking ML. In addition, while its true that there are cocky persons in the world - but they are generally detested. Its also true in movies or dramas. The ML here is a bit cocky; combined with his being too old to the pretty FL - its a recipe for viewers distaste.
