In the 37th year of the star calendar, Lantau City, which is near the sea, is a slow city infiltrated by the second-dimensional culture. Librarian Lin Yan's daily life should be sorting out old books, brewing coffee, and occasionally answering readers' questions about popular anime. Until a "Stardust Illustrated Book" with a worn cover appeared, and the strange symbols on the title page shimmered in the middle of the night - they were the "dimensional marks" he had seen in his dreams when he was a child.
After that, weird things happened one after another: a girl who often borrowed comics suddenly lost her memory and could only remember non-existent anime plots; humming of anime theme songs came from the depths of the old library, but the source of the sound could not be found; "androids" who looked exactly like classic two-dimensional characters appeared on the streets, and their behavior was completely inconsistent.
Lin Yan was forced to step out of his comfort zone and follow fragmentary clues: the missing cartoonist, the sealed dimensional research files, the secret room in the old house left by his parents... The boundaries between daily and extraordinary gradually blurred, and those truths buried by time seemed to be related to the out-of-control "dimensional fragments".
While maintaining a superficial calm, he must unravel the code of symbols, find his kind, and fight against the forces that spy in the dark. Every step of exploration is approaching a silent confession about love and sacrifice.
