This movie left me feeling sad. I'm odd maybe, but movies and dramas leave an impact on me. Enough to affect me for the rest of the day/week/ or however long. It's a simple storyline which we all would have seen in some form or another. This hurt. I was hurt when Suni left him and was hurt when she left him again for a second time. The acting is excellent and the movie, well done. I wish you could do away with bad guys in movies because they cause so much trouble to prospective lovers and people. Yoo Yeon Seok plays such a horrible villain you'd want to stop watching. Cheol-su and Suni's innocence and love are well portrayed by Song Joong Ki and Park Bo Young. I'd like to give it a high re-watch value but it hurt me enough not to watch it again. Watch it when you are not having a bad/ sad day.
