In this paper I investigated the modernity of Mujong by focusing on love and the protagonist’s subjectivity in the novel. Mujong reflected the author’s argument about ‘Jong(affection)’ and ‘Y nae(love)’ directly. Literary concretization of the author's theoretical assertion made two different effects : on one hand, the novel delivered the author's ideas of enlightenment in easy words, on the other hand, it exposed the blind spot of the author’s theoretical assertion. Yee believed that true love come from spiritual understanding and realizing inner love and affection made a person a subject. It was because he thought that a person who realized love and affection could awake his/her responsibility for others and for the society. Mujong reified this theoretical thoughts on the bases of the period's reality by building a protagonist who considered his personal love as a 'spiritual revolution'. However，literary materialization exposed the deficiency and inconsistency the fixed theoretical idea. The inconsistency could he represented by two major points. One was the protagonist Hyong-sik's intense interests in the body of Yongche, the other was the unsolved state of Hyong-sik who could not select one of the two women Son’h yong and Yongche by his own passion to the end. These two facts were resisting against the author's theoretical thoughts pointing out its aperture. The confusion brought from love made the protagonist ask his subjectivity for himself, although the author stressed Hyoug-sik’s awakening of the self several times in the story und Hyong-sik was described as a enlightened person. This self-interrogation revealed the protagonist's feeling alienated from his own belief, and this fact discovered that the described subjectivity of Hyong-sik was an artificial effect of the author's discourse. However, Yee Kwang-su solved this problem by Hyong-sik’s desire for education, especially learning from the West. This way of solution prohibited dismantling and reconstructing the pre-constructed thoughts which had its base in the West. Likewise, Yee’s illuminism could not but settling in pre-constructed identity, excluding the possibility for the liberation movement from the pre-modern society to create a space to play liberal variations of possibilities and to find out new symbolic order without certain pre-constructed orders. Thus, love in Mujong proved that the modern subjectivity stressed by the author concluded to colonial subjectivity in the end.
