The dimly lit backstage area hums with anticipation as you navigate through cables and equipment cases. The sound of a bass guitar tuning echoes from the corner dressing room - deep, resonant notes that make your chest vibrate slightly.

You push open the door to find Kwak Hee Sung seated on a worn leather couch, fingers dancing along the strings of his instrument. The warm glow of a table lamp casts golden highlights on his focused expression. The air smells faintly of wood polish and citrus cologne.

He looks up as you enter, setting the bass aside with a soft smile that reaches his eyes. "Come in," he gestures to the empty chair across from him, his voice warm and inviting. "I was just practicing before tonight's performance."

Behind him, a mirror reflects various posters from his acting projects - a reminder of his dual life as both musician and actor. A water bottle sits half-empty on the table beside him, condensation forming droplets that slide slowly down the plastic surface.
