This paper studies the gender politics of the invisible man motif shown in Kim Young-ha’s "High-tension Wires," Son Hong-gyu’s "Invisible Man," and Song Sok-ze’s "Invisible Man." The concept, closely related to flexible gender and social structure, shows the gender politics of an unconscious level in the text. Therefore, this paper studies the gender politics of our society by focusing on the relationship between the male gender and specific periods of modern and contemporary history, including the 1997 economic crisis and the 2008 candlelight vigil. Kim Young-ha’s "High-tension Wires" depicted a man who admitted only customary masculinity, as the economic leaders of the male gender met their downfall into the invisible man during the 1997 economic crisis. As a result, he tries to recover his “crashed” masculinity through sexual deviation, such as pornography, with a female classmate--but such attempts are frustrated due to the reversal of gender structure. Son Hong-gyu’s "Invisible Man" has showed the father wandering as he was unable to secure a new gender role as required in the era of de-authoritarianism and the “candlelight vigil.” The novel portrays the solidarity of anxiety leading up to the relationship between the father and the son, by focusing on the son’s psychological changes as he watches his father’s authority collapse. In these texts, we can see the flexible gender roles; whereas a loss of masculinity occurs among men, women occupy a dominant position by acquiring masculinity. Further, Song Sok-ze’s "Invisible Man" presents the possibility of another male gender. The men appearing in Kim’s and Son’s novels have to be invisible by adhering only to the customary male gender (masculine). Kim Man-soo, the hero of Song Sok-ze’s novel, was able to "care for his family by simultaneously performing “feminine” duties such as “care, embracing, and sacrifice,” as well as the masculine duty of “economic stimulus.” The role Kim Man-soo inhabits is different from the authoritarian masculinity and submissive femininity of the dichotomous gender structure. By subsumed masculinity and femininity, he has the appearance of a “man who sacrificed voluntarily” (masculinity and femininity of men). Through this, we are able to rediscover the meaning of flexible gender, and find the possibility of a new male gender required for contemporary times.
