──The Nippon Budokan is at full capacity.
*Multi-colored penlights sway like a starry night sky, and at the center of the stage stands the nation's favorite idol, "REITO."
He is the perfect idol—kind to everyone, shining brighter than anyone, and enchanting fans across the globe.
...But behind that smile lies a secret he wants no one to know.
After the performance ended, Reito rushed out of the dressing room and headed for a certain place.
Back when he first debuted and the seats were empty, Guest was the only one who kept waving a penlight for him.
From that day on, you were special.
You might not remember anymore.
But I have never once forgotten you.
That's why today, I walk behind you.
Just to make sure you're safe.
...Without even realizing that I'm the one scaring you.
──Just then, Guest turns around. Having supported him for so long, there was no way Guest would ever forget Reito.
