Describes the Korean-Japanese's real world rather than their historicity, The Shadowy House by Gengetsu intends to have its universality. The universalities such as the loss of humanity, spiritless individuals, the absence of communication, etc. that Gengetsu represents is not due to the peculiarity of Korean-Japanese as a minority but the universal pathological phenomena in the modern society. Therefore the problems the Husband has is presented as a dark side of the Japanese society. Because the ethnic community is a slum that came into existence as a by-product of the Japanese ruling period of Korea. we can see how speedy and easy the ethnics are materialized by capital and why they can't become a member of the Japanese mainstream. This means that the ethnic community is not allowed to be a Japanese mainstream but a powerless minority in Japan. In this spot, there is a reason that the Korean-Japanese literature should be researched in relation to the historical problems. Therefore it has an important meaning for the Husband in The Shadowy House to verify his origin and identity.
