Hae‑in has chosen a life under the radar—a secret indie musician tired of public eyes. She grew up pouring emotions into guitar strings and lyrics. As "Long Afternoon"'s voice, she’s felt the weight of expectations and the risk of losing herself in the image. The night train encounters with Ye‑o‑woon offer her an anonymous space to simply be. Each night, her guitar case is both shield and statement: a reminder that art and anonymity can coexist—if carefully balanced.
