You're The One - Jordan Dun x Reader

[ this is for a friend of mine :)) ] One day while at a record store in Las Vegas searching for a new CD to add to her growing collection, Y/N runs into a boy. They talk in the store about their music taste and albums they want or like. This boy, who she doesn't even know the name of, buy her a CD she wanted but couldn't afford. They part ways, but Y/N cant stop thinking about him... until she realizes who he is. what happens when the next day at a twenty one pilots concert they meet again? Will they hit it off, or will they get separated? Or... both?
