This study was conceived by the idea that Yeom Sang-seop would be newly illuminated as a modern literary figure in an attempt to provide novel education and novel history education with the materials of multicultural experiences. Of multicultural experiences to be manifested in various aspects, the topic of “mixed-blood” is especially depicted in-depth in his works. His representative works include Mansejeon, Namchungseo, Love and Crime, When Peony Blossoms Bloom, and The Son of Liberation. The daily life experienced by the characters in his novels is that of the ruled in the colonized land and also that of those who are not distant from a multicultural society. In the present study, multicultural experiences refer to the process of self-discovery through heterogeneous cultural experiences via the West among the Joseon people in Far East or the frontier. While Japan is geographically situated in Far East, its modern civilization was influenced by the West, which means that it had the same images as the West to the Joseon people. The colonial fights were a pending issue when modern literature was formed in Korea. The period was scattered with heterogeneity and hybridity. His Mansejeon, Namchungseo, Love and Crime, When Peony Blossoms Bloom, and The Son of Liberation are unprecedented in literary history in that they reflect the issue of mixed-blood through those internal and external conditions. The findings about “mixed-blood” or “mixed-blood consciousness” that is the multicultural experience in those works indicate that male mixed-bloods manage to secure national identity, whereas their female counterparts show no such consciousness. Rather they are depicted in negative ways such as leaving Joseon to search for their Japanese fathers and displaying their material and sexual desire. Even though differences in mixed-blood consciousness are revealed through man and woman, Yeom is an unrivaled writer to describe the heterogeneous and hybrid cultural contexts of the colonial period in daily life. In particular, the vividness of modern literature is found in the cases that such cities as Busan and Gyeongseong were modernized according to a plan and that the features of such spaces were embodied in the life perimeter of his characters.
