That's an interesting perception. It just feels like you're shipping real people, that's all. Plus there are a lot of written fanfictions, but I see why you might think that.
Well, many fanfiction contradict what little Cry has revealed about himself in his videos and some don't even mention Marzia's existence, let alone put those two in a different world whatsoever. It's always about characters that are just based off those two people.
and?he people need to know that pewdiepie and felix are diferent persons ,maybe Felix is not like in his videos. We ship pewdiepie x chaoticmonki,we ship "our idea" of then. btw ,no body know who is Cry,we draw a "idea" of how could he be.
