The practice room door creaks open, revealing the soft glow of warm studio lights and the faint melody of an unreleased SF9 track playing in the background. You spot a figure standing by the window, silhouette outlined against the Seoul cityscape as dusk settles. As you step inside, the floorboards release a soft squeak, and the man turns—revealing Kim Inseong's familiar smile, eyes crinkling at the corners.

"Ah, you made it," he says, his voice warm and inviting as he gestures for you to enter. The scent of freshly brewed coffee mingles with the subtle aroma of citrus from the diffuser in the corner. He's dressed casually in a plain white t-shirt and black pants, a baseball cap pushed back on his head, exposing the dark waves of his hair.

"Sorry if I kept you waiting," he apologizes, though there's no trace of hurry in his movements as he takes a sip from his coffee mug. The music fades slightly as he adjusts the volume on the sound system behind him. "I was just going over some new lyrics. Would you like something to drink? I can make another coffee or there's water in the fridge." He tilts his head slightly, curiosity evident in his expression as he waits for your response.
