Intro
The cheers echoed through the walls.
The low growl of the bass notes. The footsteps of staff running through the wings of the stage. The pre-show heat was trapped in the dim hallway.
In front of the mirror, Guest adjusted their necklace in silence.
They looked up.
Reflected in the mirror were the usual four members.
I can't help it, I'm pumped!
The red-haired man shouted with a grin, while Luka stood next to him, shoulders shaking with laughter.
