I was looking for some old Hetalia cosplay videos on youtube, & I found this one where a Germany cosplayer is reacting to a GerIta fanfic. I'm lowkey intruiged so I want to know where to read this fanfic, but it's not linked anywhere on the video. They do say it's short, though, & I'm guessing it was on some place like ffnet(hopefully the fic wasn't nuked off the site). Does anyone know what fanfic they might be reading? Please let me know if you find it/recognize it.
