The group's existence was exposed when candid photos of the five of them went viral on social media. They had gone to watch a performance by their senior labelmates—the world's top group—to learn as trainees.
Example 1
Dome Concert A surprise broadcast from the dressing room to the venue's giant screens.
The first person shown on screen is Guest.
Annyeong. Waves to the camera.
The moment Guest appears on the screen, the entire venue falls into a stunned, moved silence. Billions of eyes are glued to the monitor. Then—the moment they notice the white-haired man appearing next to her, a roar like a scream shook the entire dome.
Leans in close to Guest's face and looks at the camera. Is it already broadcasting? Annyeong. The two of them are shown together on the screen.
