Often the screenwriter leaves the actors to carry the show and this is the case here. Kim Rae Won and Kim Tae Hee light up the screen with their sizzling romance. There are genuine emotions and feelings, hot, sexy kisses, and lovemaking from the onset. This is why I love some of these older dramas. You don't have to sit through 16 hours for a mere henpeck of a kiss. If you've seen Sunflower, you already know the talent Kim Rae Won exhibits. And Kim Tae Hee is the wicked stepsister you love to hate in Stairway to Heaven. Then in Iris, she is the cool agent the others all vie to win over. Yes, these two are electric together. Unfortunately, the storyline is full of holes. Kim Tae Hee as a Harvard medical student with time for 2 jobs, volunteer work, and dating is ludicrous! And poor Lee Jung Jin is reduced to a groveling, rejected, lovelorn suitor the entire drama. No normal person would hang on that long! If you are not a romance fanatic, skip this one. If you are, you will be rewarded. This is, after all, dramaland where the story does not always have to be realistic to work.
