Lol after spending so many years in k-dramas we fans are good at predicting outcome too lol I was thinking the same thing they are going to pull that card.
WTF doesn't even begin to sum up this movie, but I guess there's true behind the plot line, as human we tend to want to stay blind to the mental illness of those around us. To me he was more guilty of that end that she was, because he truly babied and enabled her, he never took it to getting her the help that she needed even when he knew that she was not okay.
Okay will watch only for Joo Won. Because I have no doubt about his acting skills, but seriously in all of Korea they could not find a more suitable actress than Yoona. I have nothing against her but I doubt she can pull playing Nodame.
