Even though the writer is an average person who adapted to the process of making a nation in each period successfully, he caused conflict with his family and neighbors constantly. His conflicts were caused by his attitude about the ideology of making a nation. It is modernity that influenced his conscience. It's affect on his conscience caused conflict with his family. He was the centre of power in the village in every period and is a typical self-made person. But his life was not happy and he became thought of as a troublesome person. In fact he was a victim of making a nation by each government in Korea. His success made him proud of by himself but it was a trap that made him a troublesome person in his family and village.
