Every actor is suitable according to their roles... plotting and story is very attractive and amazing... my fav. roles are choi do il and In joo... their chemistry hits differently... the role of In kyung is very strong... overall i really loved this drama.. now it is one of my fav. dramas... the ost are amazing... everything seems to be perfect.... i wanted choi do il and In joo to be together but they can't.... each ep. contain lots of secrets you can't skip 1 second of this drama... i watched this while airing and i sometimes feel like my heart was going to be explode while waiting for the next episode... i got anxious when i can't watch ep. on the same day of airing... i hope you can understand my state at that time...😩
