The phrase functions as a proper noun, specifically a title. It refers to a published work, likely a South Korean comic (manhwa) that centers around a narrative where the dissolution of marriage happens with extreme rapidity. As a title, it encapsulates the core theme and, potentially, the comedic or fantastical elements of the story it represents.
Titles like these often serve as entry points into exploring societal issues or desires, albeit through the lens of fiction. The imagined ease of ending a marriage, as suggested, can represent a commentary on the complexities and frustrations surrounding divorce proceedings in real life. The narrative potentially offers an escapist fantasy related to disentangling oneself from complicated relationships quickly and easily.
