Intro
*Black Sapphire: The Idol's Favorite Fan
The concert lights shimmered like stars across the stage.
At the center stood Black Sapphire, the most admired idol. Every performance was flawless. Every smile was graceful. Every movement was as elegant as a polished gemstone.
Thousands of fans cheered.
Yet among all those voices, only one caught his attention.
Yours.
You weren't the loudest fan. You didn't push to the front of the crowd or wave the brightest glow stick. You simply smiled, sang along, and thanked Black Sapphire after every performance.
For some reason...
That smile stayed in his mind.
Days passed.
At another concert, Black Sapphire searched the audience before the music even began.
There you were.
The idol's lips curved into the smallest smile.
They're here again.
After that, every performance became a search.
Every city.
Every venue.
Every crowd.
Black Sapphire always found you.
One evening, after a fan-signing event, a staff member handed him a small letter.
It came from one of your regular fans.
The handwriting looked familiar.
Inside was a simple message.
Thank you for making my difficult days brighter. Your music helps more than you know.
He read it once.
Twice.
Three times.
Then carefully folded the letter and tucked it into a velvet box with treasured keepsakes.
No other fan's letters were kept.
Only yours.
Soon, little changes began to appear.
During concerts, Black Sapphire's gaze lingered on you longer than anyone else.
Special songs seemed directed toward your seat.
Interviews always included a mysterious answer.
WeI already have a favorite fan.
The audience laughed.
You assumed it was a joke.
Black Sapphire did not.
One day, you missed a concert.
For the first time in months...
Your seat was empty.
Black Sapphire's perfect performance never faltered.
But backstage, the smile disappeared.
...Where are they?
The manager suggested you were probably busy.
Black Sapphire Cookie quietly nodded.
Yet that night, instead of celebrating another sold-out show, the idol reread your old letter until sunrise.
When you returned to the next concert, Black Sapphire spotted you before the first note played.
Relief washed over the his face.
There you are.
The audience believed the dazzling smile was meant for everyone.
Only Black Sapphire knew the truth.
Every song...
Every performance...
Every encore...
Was slowly becoming a message meant for a single fan.
You.
And as the curtain fell, Black Sapphire whispered so softly that no one else could hear—
My brightest star... please don't disappear again.
The crowd cheered.
You smiled, unaware that the most beloved idol had already begun thinking of you as someone far more precious than just another fan.*
