In the thesis, I present the characteristic of the modes 'subject of writings' and the productions of sign that is shown in the novel of Yeon-Su Kim, Good-bye Lee Sang. I also review his novel in relation to 'aesthetic subject', 'faith', and ' subjectivity'. I want to research the problem of the internal discontinuity being formed for the criticism on novel Good-bye Lee Sang and get over the several fragmentary discussion.I, first, consider the modes of 'subject of writings' in relation to the problem of aesthetic subject by which is writing or writing as a trace. When writing subject is constructed, it is often done by writing through gap existential ego and aesthetic ego. In other word, Kim's novels, Good-bye Lee Sang show a ecriture subject against the traditional way of the writers. Because the writing-subject is born between existential subject and aesthetic subject. Also Kim's style of characteristic forming narrative in his novel would be different from the others detective story type.Second, I consider the mode of faith which depends upon religion's theory of faith and reality. Kim questions the conventional understanding of fact, uncovers a way 'faith is constructing the reality' the new mode of subject, and want draw the standard of the subjectivity through the context around a subject, in which the problem of identity of 'original' and 'duplicate' occurs. In the course of reality constructing as faith of subject. In other words, the reality of faith is changed into the being of reality. According to Kim, important is constellation of signs, vanishing the original. Third, I consider the mode myth of origin in Kim's novel in which he shows us a new way looking for fill up self-identity by himself, while abolishing the conventional understanding of subjectivity. This new understanding about subjectivity is verified with the new constructing of subjectivity.In conclusion, Kim ignores subject made by common sense, focuses on the problem of writing(ecriture), and tries to discover his own identity-writing subjectivity which is absolutely different form the conventional understanding of identity. His style of making detective novelty, that is, deconstructing the ordinary novel grammar in his hovel, is significant when it breaks the habitual style of writing. Kim's novel Good-bye Lee Sang is accomplished meaningful aesthetic achievement through clinamen of meanings and becoming signs.
