The form of novel, dealing with author's private daily experience, is one of the Korean's novelistic styles and this style of writing is closely connected with Japanese private novels since the Meiji Restoration. In the introspective novels of Lee Tae- Jun, Park Tae-Won, and Kim Nam-Cheon, the narrators, the characters, and the authors were presented as united personality, having the same identity. This unification was done on the establishment of private novelistic way of reading. Especially, through his consistent literary works, called the theory of novels or personal novels, An Hoe-Nam directly embodied the close connection between private novels and Korean novels of the 1930s. The previous evaluation on An Hoe- Nam was mainly focused on realistic viewpoints, telling that his novel moved from personal novels, absorbed in Self or Oneself, before the 1945 liberation of Korea to progressive realism novels after the 1945 liberation. Kim Nam-Cheon, who first referred an important mention on An Hoe- Nam, started this evaluation and other contemporary critics, including Lee Won- Jo, Lim Hwa, Kim Dong-Seak, and Baek Cheol, succeeded to this evaluation. However, different from the previous evaluation, the personal novels of An Hoe-Nam were understood as reflecting the ideology and social aspects of newly changed literature. The real self separated novel stories into fiction and non-fiction and understood true records, which based on author's private region, as an embodied literature. This change of literary viewpoint is an important cause of rise of personal novels. The other cause is that as entering 1930s, authors realized the inflow of consumptive culture into daily lives and the expansion of private regions with its relation. The main themes of the introspective novels in the 1930s, including the novels of An Hoe-Nam, were the livelihood matters of families and the affairs of love that were connected with related to the consumption. This fact proves these arguments. Kim Nam-Cheon's short novels, which revealed the self-disclosure and self-ridicule of intellectuals and his exposure literary and moral theory, which built up the reconstruction of new realism through private self-disclosure, as well as Lee Tae- Juns mental-life novels and Park Tae-Wons society-life novels, showed an introspectiveness of novels and we are able to give an reasonable explanation for the introspectiveness by understanding that authors are seeking literary truths through self-discoveries in the change of political and social history in 1930s. This style of writing has an analogy and a connection with Japanese private novels. A new of novel theory, the confession and self-disclosure form toward literary truths, was developed during the 1930s. Although the relationship between the Korean novels of 1930s and the Japanese private novel can be easily mentioned, this relationship can offer a wide viewpoint in reading and understanding novels in the 1930s.
