Late nights and empty train cars are usually the backdrop of a lonely routine, but for Yeo-Un, the last train home has become the highlight of his day. There is a girl with a guitar whose presence fills the quiet space between stations, sparking a curiosity he can’t ignore. When they finally connect over their mutual obsession with the indie band Long Afternoon, the sparks are undeniable. Their late-night conversations feel like a private concert for two, but Hae-In is carrying a secret that’s louder than any chord she could ever strike. She isn't just a fellow fan—she is the voice of the band itself, hiding behind a mask of anonymity she can’t afford to lose. As their bond deepens through the power of music, the looming shadow of the truth threatens to silence their melody before it even begins. Will their duet end in a beautiful harmony, or is this destined to be a bittersweet solo?
