Potential Author-Non here! I may fill this, only because I actually hoard Fanfiction on my phone (not for long car rides, but it's just something I do; I'm up to 60 tabs now with just as many in my To Read list) and it's another thing I can see Prompto doing as well. However, I may take a while as I am a graduating student about to go on an internship and don't have much free time. But expect something at least :)
