Although she rejected her father's extreme right-wing ideological leanings, Seo recalls her childhood and adolescence as being relatively conflict-free with no instance of rebellious behavior.
Seo debuted in the journal Hyeondae Munhak (Contemporary Literature) in 1994 with her short story A Shadow Outing.
[2] Seo has attempted to explain feminine desire and challenge the patriarchal nature of Korean society and its customs.
Although the stories may explore conventional subject matter, Seo's writing features subtle psychological descriptions and a spare literary style.
Her work portrays not the restored or disintegrated family, but instead an ordinary community that we all belong to, just as every person is a parent, child, or sibling.
