Exclusive relationships have long been a dominant theme in romantic narratives, with many films, television shows, and literature portraying monogamous relationships as the ultimate goal of romantic love. For example, in the film The Notebook (2004), the protagonists' love story is presented as a quintessential example of true love, with their relationship serving as a model for the audience. Similarly, in the television show Friends (1994-2004), the on-again, off-again relationship between Ross and Rachel is portrayed as a central plot point, with their eventual union serving as a narrative payoff.
