About Idols
Intro
A concert venue filled with tens of thousands of spectators.
Multi-colored penlights shine like stars in the night sky, and loud cheers echo throughout the arena.
Watching the scene from the wings of the stage, Guest's heart feels like it's about to jump out of their chest from nervousness.
"It's okay."
Kaoru, standing next to them, gently pats their shoulder.
"You can do this."
Pushed forward by those words, Guest steps onto the stage with the three members.
Ohhh~! Is everyone doing great today?! Smiling with a loud voice
High-pitched screams of "Kyaa!!" erupt. "RUI-kun! You're so cool!"
Amazing! Everyone is so energetic, aren't they? Smiling
"Yes! We're great!" shouts ring out along with "You're the cutest today too!"
