One concert. One city. One completely unplanned moment that changes everything. When the lights fade after a concert in Belgium, one unexpected encounter sets off a quiet rebellion. Y/N isn't looking for fame and Hyunjin isn't allowed to look for anything real. But in a city full of cobblestone streets, chaotic group trips, and stolen moments, the line between real and off-limits gets dangerously thin. What starts as a spark turns into something impossible to hide. And maybe even harder to protect. An emotional rollercoaster with found family vibes, forbidden feelings, group chaos, and a connection that hits way too fast and way too deep. A Hwang Hyunjin x Female reader fanfic
