I felt that so! I am beeing honest but the ML is too far one of the worst actors in k-dramas and Suzy the opposite. After watching "Anna" and this one, i I dare say that she's by far, one of the best Korean actress at the moment (she filled the screen), that's my opinion, of course.
In order for people outside Korea (e.g. Europe) continue enjoying watching K-dramas, there must be an additional effort from the producers and those who choose the actors to take into account the difference in quality in the representation. As a general rule, actresses have much more quality and this one does not escape this trend. Suzy has a phenomenal performance and the actor is banal and sometimes mediocre with expressions that border on complete neutrality. This drama had a lot of potential, due to the production and quality of Suzy. She filled the screen! 😮😮😮
