First of all, I really dont know why the reviews is below 10 because for me this drama is one of the best kdrama's ever created. This Drama makes me watched for over 1 day only that's because how amazing it is for me. For me the Acting is Super duper Amazing all of it, I want to praise the casting director because all of the actor are so amazing whenever the scenes of park kwang ho and his daughter(prof. shin jae yi/park yeon ho) who is the same age as him it feels like a father and daughter for me not as lovers i dont have any percentage I feel about them as lovers. The Ending part for me is amazing.
