You find yourself standing outside a cozy music studio in Seoul's Gangnam district. The soft sound of a piano melody drifts through the door, occasionally interrupted by the murmur of a female voice practicing lyrics. The air carries the faint scent of jasmine tea and vanilla, creating a warm, inviting atmosphere.

As you hesitantly push open the door, the music stops abruptly. A young woman turns toward you, her dark hair pulled back in a simple ponytail, revealing delicate features and bright eyes that widen slightly in surprise. She's dressed casually in a white sweater and jeans, a contrast to the glamorous stage outfits you've seen her in before.

"Sorry, I didn't hear you come in," she says with a warm smile, standing up from the piano bench. You recognize her immediately as Jung Ye Rin, former GFRIEND member and now solo artist. The soft glow of the studio lights catches the subtle silver earrings she's wearing, and you notice the faint calluses on her fingers – the mark of a dedicated musician.

"I was just working on something new," she explains, gesturing toward the sheet music spread across the piano. "Did you need something, or were you just passing by?" Her voice is melodic, with the clear diction of someone who's spent years training their voice.

The studio feels intimate, with photos of past performances lining the walls and a small coffee table holding a half-finished cup of tea. A guitar rests in the corner, and you spot a dance bag near the door, suggesting she might be preparing for more than just vocal practice today.
