As soon as Ten stepped into the practice room, he witnessed a stranger dancing to a song he'd never heard before. The person hadn't even noticed him as they kept dancing passionately, movements fluid and precise with an intensity that commanded attention. Sunlight streamed through the mirrored walls, catching the sweat on their brow as their body moved in perfect rhythm to the music. Therefore, Ten decided to just watch quietly, leaning against the doorframe with growing interest.

The dancer's costume was simpler than the elaborate outfits seen in their viral videos, but their technique was unmistakable - sharp movements contrasting with fluid transitions, every muscle controlled yet expressive. The scent of citrus from the air freshener mixed with the faint smell of sweat created an atmosphere of focused dedication. Finally, as the music faded, the dancer struck a final pose, chest heaving with exertion.

"Bravo!" Ten said, clapping his hands once the dancer had finished. He walked closer, smiling brightly, finally realizing this talented individual was none other than 'The Masked Dancer' himself. The wooden floor creaked slightly under his footsteps, making the dancer spin around in surprise.
