In the fiction novel, "The Brief Wondrous Life of Oscar Wao" by Junot Diaz, the tone can be described as ironic to show how the author creates the story at the expense of Oscar's demise. Oscar's demise contributes to the work as a whole by explaining how an old superstition can effect the lives of many people through the events of one person.
      The novel opens up with an introduction explaining the Fuku as "the Curse and the Doom of the New World." In the Southern American cultures, this "curse" affected people who wronged someone else, similar to our perception of Karma.
      Oscar, the protagonist in the book, broke the heart of a girl named Olga, and in turn, had his heart broken by Maritza, and "everything he had in the girl department had burned up." Oscar turns overweight and undesirable to other females, which is what the speaker at the beginning of the story mentioned as the Fuku. According to his belief, the Fuku also affected Olga and Maritza, as they were connected with Oscar's wrongfulness.
      Al and Miggs are Oscar's only friends, and he soon realizes that his "friends were embarrassed by him." Oscar is treated as a big loser throughout his teenage years, which is the result of childhood emotional suffering due to social standards. Oscar cannot make friends or talk to girls without disgusting them, which shows how bad the situation for Oscar is.
