Ji Seong-ho is a North Korean defector who lives in South Korea, where he works to raise awareness about the situation in North Korea and to help fellow defectors.
Seong-ho managed to make his way across China. He was ultimately reunited with his brother in South Korea. He left the North "because I was in search of freedom. In more simple terms, I wanted to be treated as a human."
