This show despite the many plot holes is still good. The ML has an unquenchable thirst to reach the top after the death of his father and angry at the world for having lived a life in poverty , he sets out to climb the mountain by making big leaps. The climb changed his character and each decision got him closer to falling of the mountain. The ending made sense, he returned to the place his father was resting as he could no longer continue living with the guilt of having made the same decision that got his father killed. The ML had several chances to stop his climb and rest and lookback at the beautiful natural landscape but he failed to lookback as such he didn't realize where he went wrong. As for the FL many have commented that she has no expression, I disagree her character was not an emotional one she has to show a strong powerful face and never to show her weakness as everyone around her is looking to pounce on her, even the brother she was close to betrayed her. Imagine living like that, it's hard. When she had to show emotion you could see them in her eyes, which showed whether she was angry, sad or happy. Throughout the show I never saw her smile, laugh, or giggle. I pitied her as in the end she was left alone.
