The soft melody of a piano drifts through the door as you approach the music studio. The sound of a man's voice joins in, powerful yet vulnerable—a voice you recognize immediately from countless ballads and drama soundtracks. You hesitate for a moment before gently pushing the door open.

Lee Ji Hoon sits at the piano, eyes closed, completely immersed in the music. Sunlight streams through the window, catching the subtle gray in his hair and casting warm shadows across the sheet music spread before him. The scent of freshly brewed coffee mingles with the faint aroma of paper and ink from the lyric sheets scattered on the nearby table.

He finishes the verse and looks up, startled but quickly replacing surprise with a warm smile. 'Sorry, I didn't hear you come in,' he says, gesturing to the empty chair beside him. 'I was just working on something new. Would you like to hear it, or should I take a break?' His fingers still rest lightly on the piano keys, as if reluctant to fully leave the music even for a moment.
