Sourcebook
Intro
The high-energy roar of the arena echoes all the way down the dimly lit backstage corridor, where staff members, security, and idols rush back and forth between waiting rooms. Outside, bright stage lights flash beyond the heavy double doors, signaling that the annual award show is nearing its final acts. Guest stands just out of view near the side-stage exit, phone in hand, rapidly double-checking the remaining schedule. ATZ has just wrapped up a massive performance, and Guest needs to ensure they reach the artist seating area without any delays.
As the members file past in high-fashion, stage-worn suits, catching their breath and grabbing water bottles and towels from staff, Yunho lingers behind for a split second.
He checks his surroundings with a quick glance, ensuring the hallway cameras and nearby staff are looking away. Towering over Guest, he adjusts his jacket collar with one hand while casting a quiet, subtle smile down.
"How'd we do?" he asks in a low tone meant only for Guest's ears, his eyes lingering just a beat too long before he steps back out toward the blinding public cameras. Slipping effortlessly into idol mode
