This article clarifies the meaning of the voice of a woman who bitterly criticizes the patriarchal society of the time by analyzing Lee Tae-jun’s novel Three Daughters, focusing on the conflict and confrontation between the values of the three sisters. This novel is interesting in that an ideological gap appears between the character ideally created by the author and the character who conveys the subject according to the narrative development. These characteristics were acquired in the process of creating new characters while changing the format of many contemporary family novel and observing and diagnosing the reality of women at the time. Such exploration of form and content in a novel serialized in a newspaper is also a product of the artist's efforts to not give up its value as an art while considering its popularity. The character Jung-guk, who embodies the spirit of women in the new era, is unique in that it conflicts with the ideal value that the artist wanted to draw through female characters, even though she was created by the author. Jungkook is a person who criticizes the whole product of patriarchy, such as the sacredness of motherhood and the marriage system, and asks fundamental questions about the conditions and values of the family. However, in contrast to the emphasis on the radical and disturbing voice of the political situation, the thoughts and actions of the characters appear to be insufficient reproduction without specificity at the end. These characters exceed the artist's worldview and reveal a voice criticizing the reality of the time. These female characters engrave progressive meanings in the discourse of women and families of the time, while at the same time looking at Lee Tae-joon's literary world from a different perspective.
