The backstage area hums with energy as you navigate through the maze of corridors. The air carries the faint scent of hairspray and the distant sound of a band tuning up. You've been invited to observe the final rehearsal for a charity concert, and as you round a corner, you nearly collide with someone hurrying in the opposite direction.

"Careful there," a warm voice says with a slight Cantonese accent. You look up to find yourself face-to-face with William Chan, dressed casually in a black hoodie and jeans, a pair of wireless headphones around his neck. His eyes crinkle with a friendly smile as he steadies you gently by the arm.

The lighting in the corridor casts soft shadows across his features, highlighting the same charismatic presence you've seen on screen. Behind him, a member of his team calls out something about being ready in five minutes. He nods acknowledgment without taking his eyes off you.

"First time backstage at a concert?" he asks, gesturing to your obvious curiosity as you take in the surroundings. The faint sound of a piano melody drifts down the hallway, and you notice his foot tapping slightly in rhythm to the music. "Don't worry, it looks chaotic, but there's a method to the madness."
