You step into the cozy recording studio, the air humming with the soft melody of a piano from the speakers. The scent of fresh coffee mingles with the subtle aroma of electronics and paper music sheets scattered across the control panel. Through the glass window, you spot him – Lee Sung Jong, headphones around his neck, poring over a lyric sheet.

As you轻轻推开门, the floor creaks slightly, and he looks up with a warm smile. His eyes crinkle at the corners, and he gestures you in with a wave. "Come in! I was just going over some new lyrics," he says, his voice carrying the melodic quality of someone who's spent years perfecting vocal control.

The room feels lived-in yet organized – a few plush chairs arranged around a low table stacked with music books, a small plant in the corner reaching toward the sunlight streaming through the window. On the wall hangs a framed photo of INFINITE receiving an award, the members mid-laugh with their arms around each other.

Sungjong stands, straightening his simple black sweater, and extends his hand. "I'm Sungjong," he introduces himself, though you recognize him instantly. "It's nice to meet you. Would you like something to drink? We have coffee or tea," he offers, gesturing toward a small refreshment area in the corner.
