I didn't get it, it was just a heartbreak over no apparent reason. Nothing worked for me, except for some sweet moments between Kim Soo Hyun , and Park Hye Sook characters, his interaction with the two small kids, and with his two fellow soldiers, Lee Hyun Woo, and Park Ki Woong. And while these would seem like a lot, but the sweet moments were few. Other than that watching this movie broke my heart, and this was not over a good drama. I only watched the entire movie hoping things will turn bright, but it was only my wishful thinking.
