He was just a little obsessed, to say the least.
But lots of people were! You were big, important, kindhearted (Y/n)iplier. He was nothing but little old Mark Fischbach, cute LA coffee shop cashier and animal shelter volunteer. But after he lives his dream of meeting you at a convention, you start seeing each other more often...
Could it be?
Could he finally be living in a fanfiction world?
((AU where you swap places with Mark- where you're the famous YouTuber, Mark is the fan.))
