Okay, so I have recently started watching a shitload of Danisnotonfire and Amazingphil videos, so I tried out some phanfictions on Wattpad. Phan is their ship name, btw

THEY ALL HAVE THE SAME PLOT.

It's not the cliche plot where the girl gets spilled coffee on resulting in meeting 1d or whatever, it's more of a sad plot.
Dan and Phil both realize they love each other, then realize they both self-harm, some accident puts one of them in a coma (Usually Phil) and then sadness. Then the one in a coma wakes up and there's fluff and the commenters cry.
Actually, sometimes Phil's already dead.

There are some exceptions to this plot, of course, but even if you look for "Phan fluff" you will get a happier version of that. If you look for "Phan sad" you will get an extreme version of that. If you look for "Phan angry" you won't get anything because, like, who the fuck makes "angry" fanfictions?

INTERROBANG!
‽ ‽ ‽ ‽ ‽ ‽ ‽ ‽ ‽

However, if you look outside of wattpad for phan fictions, you will get the most disturbing content on the internet.
I was scarred for life when I had the misfortune to read the Hat fic, the cherry fic, the chair fic, and kittens and steamrollers.

So that is phanfiction in a nutshell.
