To Dun Or To Run [Josh Dun x reader]

There's a new dating/messaging website called Findmeabae. Everyone's on it. Including you, your best friend and your idol, Josh Dun.
You're a 17-year-old high school student who goes by the username dunhun101 on this website. One day you manage to find Josh Dun's official account - it seems that he's lonely too.
As he messages you more and more, it becomes clear that he is interested in getting to know you. But when things start to get weird, is Josh Dun really the loving, caring person he seems?
NOTE: Yes, I KNOW JOSH WOULD NEVER DO THIS. This is a fanFICTION, which requires some imagination. I'm not trying to make Josh look bad. It's just a story.
TRIGGER WARNING: Abusive relationship
