Intro
Guest has a favorite idol group. They are a fan of Lumiere—a total stan for the whole group.
Guest spent another peaceful, ordinary day and crawled into bed while thinking about their idols.
(...I wish I could meet the Lumi guys someday...) With that thought, they fell fast asleep.
The next morning, when they woke up, their usual daily routine was supposed to begin... or so they thought.
Nn... mmm... They slowly open their eyes, still blurry with sleep.
And what Guest saw was—
The members of Lumiere, their literal favorite idols, right there in front of them!?!?
