Kim Yu-jeong and Lee Hyo-seok share many common features including creative activities in the 1930s, hometown in the Yeongseo region of Gangwon, influences of Marxism and Western literature, membership of Guinhoi, and prolific works during a short period of time. Despite their common features, however, they are different in literary viewpoints and worlds. The two writers wrote original and distinctive novels that transcended the boundary between realism and modernism, between KAPF and Guinhoi, and between aesthetic and realistic consciousness, thus enriching literature in the 1930s. Criticizing art for art and new psychological literature, Kim was oriented toward literature about love that could contribute to the entire mankind. He believed that technical skills and artistic techniques were not enough to deliver the content right and could not be the core of literature. He criticized individualism represented by Nietzsche and Malthus and sought after a love community based on Kropotkin's mutual aid theory and Marx's capital theory. Based on this literary viewpoints, he chose a novel composition method that developed around events and characters' actions and depicted the extreme aspects of life among the lower class that moaned and suffered in the modern colonial capitalist society including farmers and peddlers with bottled liquor. Singing Yukjabaegi and putting on the Joseon clothes all the time, he used folksy Pansori-style sentences in his novels. He also published Hong Gil-Dong Stories and Dupo Stories, putting an emphasis on the mutual aid and love of the national community. Lee Hyo-seok, on the other hand, sought after romantic realism based on the art-for-art principle and aestheticism. His literature based on his aesthetic consciousness advocated the middle between romance and reality and placed importance on artistry, technical skills, techniques, inner psychology and spatial description. In his novels suggesting signs and subplots with beautiful night landscapes and refined synaesthetic poetic expressions, he revealed his thematic consciousness by putting life and reality in the background and depicting the scenery of a village and nature under the influence of Mansfield and Chekhov for their background descriptions and Dostoevsky and Maupassant for their inner psychology. The literary worlds of the two authors are revealed clearly in their positive or negative assessment of James Joyce. Changing his daily life habits into Western culture in pursuit of modern Western literature, Lee wrote novels mainly dealing with the desire and psychology of elite intellectuals including the upper class that climbed the status ladder during the transitional time, newspaper reporters, writers, carriers of culture, doctors, and heads of film studios. His literature that is Western, urban, and modern made Korean literature in the 1930s colorful and refined by pursuing art for art.
