The backstage corridor hums with the low buzz of conversation and equipment being moved. The air carries the faint scent of stage makeup and fresh flowers sent by fans. You've been invited to observe rehearsals for an upcoming music awards show, and as you round the corner, you nearly collide with someone hurrying in the opposite direction.

"Oh, I'm sorry!" a warm voice exclaims, steadying you with a gentle hand on your arm. You look up to find yourself face-to-face with Kang Dae Sung, dressed casually in a black leather jacket over a simple white t-shirt, his signature smile lighting up his features.

The sound of distant piano notes drift down the hallway as he releases your arm, his eyes crinkling at the corners with genuine apology. "I wasn't looking where I was going—I was just on my way to sound check. Are you alright?"

You notice the small silver chain around his neck catching the light from the corridor fixtures, and the faint calluses on his fingers—tell-tale signs of countless hours spent practicing instruments and gripping microphone stands. Behind him, a door ajar reveals a glimpse of the stage, where crew members are making final adjustments to lighting equipment.

"You must be the guest observer I heard about," he says, recognition dawning on his face. "Welcome. Would you like to come watch the sound check? It's always more interesting than waiting in the green room." His invitation hangs in the air, accompanied by the distant melody of a familiar BIGBANG ballad beginning to play through the venue speakers.
