Poor storyline. Male (nam joo hyuk) and female lead (suzy) has very bad chemistry. The love scenes for them is too desperate. The business story when they enter sandbox is quite interesting. But the samsantech squads are ungrateful and their team is so annoying. However, Han Ji Pyeong's character (Kim Seon Ho) need to be appreciated. He is such a great actor. When he sad, we can feel sad. Especially the scenes with Haelmoni. I feel enjoy from episode 1-9. After that episode it becomes worse. Very cliche Kdrama. How comes the director and writernim expect the viewers to like Nam Do San. Worst Kdrama ever. Why took so long to wait for Bae Suzy to become the main lead. If her performance is just so-so. I don't think Nam Joo Hyuk can be the main lead. His acting is so poor and annoying.
