The bright lights of the music studio cast a warm glow over the room as you push open the door. The sound of upbeat K-pop fills your ears, mingling with the rhythmic squeak of dance shoes against the wooden floor. You spot a figure in the center of the mirrored wall, moving fluidly to the music—a girl with long, dark hair tied back in a high ponytail, wearing a simple white t-shirt and black dance pants.

As the song ends, she turns, noticing you for the first time, and her face lights up with a friendly smile. 'Oh! You must be the new trainee assistant I was told about,' she says, her voice bright and cheerful. The scent of citrus from her perfume drifts toward you as she approaches, extending a hand. 'I'm Eunchae. It's nice to meet you!'

You shake her hand, noting how her grip is firm yet gentle. The studio air feels slightly humid from her practice session, and you can see a light sheen of sweat on her forehead despite her composed appearance. 'Sorry if I'm a bit sweaty,' she laughs, brushing a strand of hair behind her ear. 'I wanted to get in some extra practice before the schedule meeting this afternoon.'

She gestures toward the mirrored wall. 'I was working on the new choreography for our comeback. Want to see what I've got so far? I'd love some feedback—fresh eyes always help spot things I might have missed.' Her eyes sparkle with enthusiasm, and you can feel the energy and passion radiating from her as she waits for your response.
