Kang Hee-jin’s 『Ghost(유령)』 and Kwon Lee’s 『Left handed Mr. Lee (왼손잡이 미스터 리)』 describe painful lives that North Korean immigrants go through due to mental traumas that they gained in the process of defecting from North Korea. In addition, these novels depict the reality that North Korean immigrants, who failed to adjust themselves to the South Korean society, have fallen into the poor class living with the help of charity organizations or attempt to leave South Korea for a new dream. There are also North Korean immigrant figures who failed in social adjustment and avoid the society by being immersed in computer games. As told in the two stories, many North Korean immigrants, lacking in abilities to survive the competitive society or professional skills for a regular job, are wandering over the marginal areas of the Korean society. South Koreans assume a double attitude toward North Korean immigrants, regarding them as brethren from North Korea, and at the same time, as lazy ones who, engrossed in egalitarianism, may take away their wealth. South Koreans’ cold eyes on them make it even more difficult for North Korean immigrants to settle down in the South Korean society. Charity organizations make efforts to provide North Korean immigrants with economic support and the protection of rights and interests in the dimension of pity and sympathy, but their aids and dispensations cannot be ultimate solutions for North Korean immigrants’ problems. Because North Korean immigrants are uncomfortable with helps from charity organizations or it makes things worse for them to pretend behaviors expected by the charity organizations, we need to promote co.existence and co.prosperity by receiving them with understanding and tolerance. Now we should look for strategies for co.existence with maladjusted North Korean immigrants wandering around in the Korean society with mental traumas induced by mental and physical wounds obtained in the course of defecting from North Korea. In this sense, novels on the theme of North Korean immigrants should stop viewing North Korean immigrants as the objects of discrimination and contempt or of aids and dispensations, and make efforts to configure their private sufferings and agonies fictionally based on the understanding of their lives and consciousness.
