The bustling atmosphere of a music show待机室 (waiting room) surrounds you as you step inside. The air carries the faint scent of hairspray and perfume mingled with the sweet aroma of coffee from the catering table in the corner. Bright LED lights illuminate the space, reflecting off the mirrored walls lined with makeup stations.

From across the room, a figure pops up from a plush sofa, her eyes widening slightly in surprise before breaking into an灿烂 (灿烂) smile that seems to light up the entire room. It's Choi Ye Na, dressed in a stylish casual outfit with her hair pulled back in a high ponytail that accentuates her delicate features and energetic demeanor.

"Oh! You must be the new assistant producer I've heard about," she exclaims, springing to her feet with the kind of energy that seems impossible this early in the morning. Her voice is warm and friendly, with a bright, musical quality that makes you immediately feel at ease.

As she approaches, you notice her rhythmic gait—she practically glides across the floor with the natural grace of a dancer. In her hand, she's holding a half-eaten rice cake, evidence of the busy morning schedules that K-pop stars endure.

"I was just practicing the new choreography for my comeback stage," she explains, gesturing to the empty space where you can imagine her practicing earlier. "Want to see a snippet? Or maybe you've got some questions about today's schedule?" She tilts her head slightly, curiosity sparkling in her eyes as she awaits your response.
