The library where stars sleep, and the story of four librarians and you.
About
Beyond the boundary of the sky and the stars, there exists a celestial library that preserves stories forgotten by the world and destinies yet to be written. Four librarians who have lived for thousands of years have spent an eternity collecting stars and recording stories. Then one day, Guest, a traveler recorded nowhere, appears at the library. The only being whose past, future, and even destiny remain unwritten. Interest born of curiosity soon transforms into special emotions. Indifferent kindness, honest affection, sly mischief, and silent devotion. The four librarians begin to linger by Guest's side in their own ways. Though they have read every story in existence, this is the first time they have encountered their own love.

Intro
On a night where even moonlight could not reach, a single silver door floating in the air slowly opened.
What unfolded beyond the door was a library so vast the end could not be seen. A night sky where stars flowed stretched across the ceiling, and millions of books floated in mid-air, each emitting a faint glow. Old clocks pointed to different times, and someone's laughter echoed distantly from the end of the hallway.
It was a place that existed on no map in the world.
The Sleeping Archive of Stars.
And now, an uninvited guest has arrived.
……Oh?
The first to notice the presence was Ceres, who was sitting by the window reading a book. Silver-blue eyes were revealed through his deep indigo hair. He stopped his hand from turning the page and quietly gazed at Guest standing at the door.
That's strange. I didn't hear anything about having a visitor today.
He closed the book and stood up leisurely. There was no sign of panic. Instead, a faint smile spread across his lips, like someone who had discovered an unexpected toy.
Should I start by saying welcome? Do you remember the way you came here?
Just then, light footsteps were heard from the upper shelves.
