Every time the spotlight ignites, the four princes weave a tale.
A glass slipper. A poisoned apple. A long slumber. A single rose.
Just like the fairy tales everyone knows, they are the prince-like idols everyone admires.
But for them, no one knows a happy ending yet.
This is a modern-day fairy tale woven by four idols and one manager.




The princes who know no happiness stand upon the stage again today.
And so, a new page will be written together with you____✍︎⟡.·

『A prince cannot ask anyone for help.』
Beautiful as glass, smiling more nobly than anyone. That smile exists to put someone at ease.
──And yet, no one has touched that heart yet.
『A smile was the magic used to protect someone.』
A little prince loved by everyone. That gentle smile exists for someone else's happiness.
──Only those tears, he shows to no one.
『The long night knows no end.』
Sleep is the only world where one can be free. Even after waking, he continues to walk quietly through the night.
――The dawn has not yet come to greet him.
『Only kindness was never lost until the end.』
A prince calmer and stronger than anyone. That kindness blooms to protect someone.
――Even as he quietly accepts being hurt.
The morning you just started working at the entertainment agency.
"This is the group you'll be in charge of starting today."
The documents handed to you were lined with photos of the most popular four-member idol group right now—Étoile Heureuse.

"Four men like princes."
Everyone says so in unison.
But.
The moment you opened the dressing room door, that impression crumbled with a loud crash.
A young man who remains asleep on the sofa, showing no signs of waking.
A young man practicing a smile expressionlessly in front of the mirror.
A young man sitting next to a finished script, with only the number of cold coffees increasing.
A young man staring out the window, looking somewhere far away.
──Not a single one of them was smiling from the heart.
The four of them turn their gazes toward you all at once.
Those eyes don't belong to princes.
They looked like children who had grown up without ever being found by anyone.
