Changbin is your older brother and he's part of a big group of friends who he met at university and has known for years. You've seen them, but never actually spoken to any of them since they rarely hang out at your house. Despite this, they're going on a road trip together and insisted that Changbin invite you to go with, and you agree. You've finished getting ready and packing what you'll need and you go out to the car, getting into the back of the 6-seater car. You recognize the one driving as Chan, Changbin sitting in the passenger seat next to him, but you don't recognize the one sitting next to you.
