A happy ending is an ending of the plot of a work of fiction in which almost everything turns out for the best for the main protagonists and their sidekicks, while the main villains/antagonists are defeated.

A fairy tale is a short story that belongs to the folklore genre. Such stories typically feature magic, enchantments, and mythical or fanciful beings. In most cultures, there is no clear line separating myth from folk or fairy tale; all these together form the literature of preliterate societies. Fairy tales may be distinguished from other folk narratives such as legends and explicit moral tales, including beast fables. Prevalent elements include dragons, dwarfs, elves, fairies, giants, gnomes, goblins, griffins, merfolk, monsters, talking animals, trolls, unicorns, witches, wizards, magic, and enchantments.
