The author keeps the two characters apart for most of the story, before inevitably having them end up together.  

Romance

Stories in which the protagonist is placed in physical danger, also characterized by exciting near misses, as well as daring and courageous actions. Stories are fast-paced, with growing tension, plus a climax that offers some relief to the the reader.

Action/Adventure

Science fiction is a literary genre that explores imagined futures shaped by scientific and technological advancements. While early works in the genre, such as Francis Bacon's *New Atlantis* (1627), appeared in the 17th century, its themes gained broader cultural resonance starting in the 18th century. This coincided with a new societal expectation that technology would continually transform the future, a departure from the centuries of stagnant living standards that preceded it.

Science Fiction

Similar to science fiction, but uses kingdoms and realms instead of planets, star systems, galaxies, and universes.  Like science fiction, involves a large amount of world-building. Fantasy stories are often characterized by the use of myths, along with other-worldly ideas and concepts, as well as taking cues from real-world historical settings, such as the Dark Ages.

Young Adult stories often feature diverse protagonists who must face challenges and changes. 

Young Adult

New Adult

These are scary stories involving one set of characters being pursued by another set of characters, who the protagonists must escape from/and or defeat. In these stories, however, the antagonists are often demonic and/or supernatural beings.
