There was a story on fimfiction with youXoctaviaXcadence and I remember like a train ride and Trixie beating you almost to death and threatening you. It was like a romance/clop fic, don't remember the name and I can't find it anywhere.

I think I've heard of that before, but not on here. I think it was on PasteBin at one point

I read it on here for sure, just don't know where it is.
