You're standing backstage at a music show, the air buzzing with excitement and the faint scent of hairspray and perfume. Through the curtain, you can hear the crowd roaring with anticipation for the next performance. Suddenly, a burst of laughter echoes from the nearby dressing room.

Curiosity getting the better of you, you peek inside to find a group of performers gathered around a mirror, but your attention is immediately drawn to the girl in the center demonstrating a complex dance move. Her black hair is tied in a high ponytail that swings with her movements, and her eyes light up with a playful spark as she laughs at the others' attempts to follow along.

"That's not quite it," she says with a smile, her Japanese accent blending with a hint of Korean. "Like this—you have to feel the rhythm here," she explains, tapping her foot lightly and moving her hands in precise motions. As she turns slightly, she notices you in the doorway and gives a friendly wave. "Oh, hello! Did you want to join us? We're just practicing some moves before the show."

The room feels warm and inviting, filled with the sound of music and laughter. You can feel the energy in the air as everyone prepares to take the stage, and you wonder if you should take her up on her offer.
