So the birthday girl wished that an invisible entity would force her to eat her cake endlessly with bare hands, while her friends stared at her? Yeah, don't do that!
But maybe I just overcomplicate the overcomplication. I have a theory: the girl made a wish, so she no longer had to use cutlery ever again! It's strange, very strange in fact, making the others petrified by indignation, and they had to watch her indecency over and over and over again, indefinitely, or until the protagonist apologizes for her lack of manners... or until she is physically unable to eat more cakes. But what if she really, really likes chocolate cake? We will never know. It seems like the unseen force is very perverted (messy mukbang isn't my thing, but different ghosts, different tastes), or have a deep rooted enmity with baked goods. Very awesome short film, but only if table etiquette is exceptionally important to you!
