I have watched alot of kdramas and movies with the worst cast but I am surprised to see that such good cast could not even save this movie. It was a big disappointment. The characters were not written properly. Details were missing and the message of the movie was very unclear. I think the director failed to do his job properly. The movie may be written good but did not turn out good in visuals at all. I don't know if it's the story or the director but I will never watch this again. I watched the whole for the best cast ever but it is indeed one of the worst movies
