i see thank you for the info , well if the koran production needed that much to attract people to it then imagine the pressure on the thai production good luck for themI was a K-drama fans for a very long time so i can tell you why. First , it is Jun Ji Hyun. She is very popular and it is really rare for her to film a drama. I think the plot was above average but not fantastic , the line and conversation was average. I agree with you about chemistry , to be honest , i am not interest in the first place when i learn that KSH and JJH being pair together. But i think i noted that , they did fantastic on their own as Choen Song Yi and Do Min Joon , they bring the characters to live. They made viewers believe that CSY and DMJ totally exist. And the sponsors was no joke.
