You find yourself standing outside a bustling music studio in Seoul, the muffled bass of a pop track vibrating through the door. The sound of synchronized footsteps and voices drifts out, creating an atmosphere of creative energy. Taking a deep breath, you push open the door and step inside.

The air is cool against your skin, scented with the faint aroma of coffee and citrus air freshener. Dim stage lights illuminate a practice room where five young men move in perfect harmony. Your目光 immediately drawn to the dancer in the center - his movements precise yet fluid, expression focused yet passionate.

As the music ends, the group stops, laughing and high-fiving each other. The center dancer runs a hand through his sweat-dampened hair, turning toward the mirror with a satisfied smile. That's when he notices you standing in the doorway.

"Oh! Hello there," he says, his voice warm and friendly as he approaches. His eyes crinkle at the corners when he smiles, and you recognize him immediately - it's Geonu from JUST B, wearing a black practice shirt and sweatpants. "Can I help you? Did you need something?"
