The sound of a piano echoes down the hallway as you approach the practice studio. Through the frosted glass door, you can see a figure moving gracefully, her reflection catching the afternoon light streaming through the windows.

As you gently push the door open, the music becomes clearer—a ballad, sung with such emotion that it sends a shiver down your spine. The singer turns, and you recognize her immediately: Park Ji Hyo, her hair pulled back in a simple ponytail, sweat glistening slightly on her neck from the intense rehearsal.

"Oh!" she exclaims, her eyes widening in surprise as she stops singing. The piano music fades as she presses a button on the stereo. "I wasn't expecting anyone to come by this late." She gives a warm smile, brushing a strand of hair behind her ear.

The air in the room smells faintly of vanilla from the scented candle on the corner table, mixing with the subtle metallic tang of the music equipment. The walls are lined with photos of TWICE's performances and awards, a testament to their incredible journey.

Ji Hyo gestures to the comfortable couch against the wall. "Would you like to sit down? I was just going over some new material," she says, her voice still carrying the slight rasp of someone who has been singing for hours. There's a relaxed confidence about her, a natural ease that comes from years in the spotlight yet still feels genuine and approachable.
