The opera Peppermint Candy (2021) composed by Lee Geon-yong and scripted by Cho Kwang-hwa was produced based on the film Peppermint Candy (2000), directed by Lee Chang-dong. In Peppermint Candy, Kim Young-ho, a 40-year-old male, experienced turbulent Korean modern history such as the IMF crisis, the May 18 Gwangju Democratization Movement in 1980, and the June 1987 Democratic Uprising. And in the opera, he wanders in reproach, shame, and anger, and ends up throwing himself into an oncoming train. The work asks the audience what eventually led to the tragedy of young Kim Young-ho's life. This article interprets what the opera Peppermint Candy wanted to convey through the tragic story surrounding a character named Kim Young-ho and, explores the way in which artworks think about human desires formed in the layout of society, based on the philosophical thinking of Gilles Deleuze and Felix Guattari, who conceptualized human desires at a social level rather than at a personal level.
