I thought the chemistry between the main male and female leads was good and they looked good together. The main actors also did a commendable job of portraying their characters' personality changes. The costumes were nice and not cheap looking. It also looks like a lot of money was spent on the buildings and sets. However, I do believe that the drama could have been more concise as there were too many events introduced without enough time for viewers to process them. The last three episodes were a bit confusing.
