The heroine Xiaoyou is a fantasy girl who likes to doodle random comics in textbooks, notes, and drafts. Once, when Xiaoyou was watching a new work, she discovered that the boy in the comic was also looking at her affectionately. At first, Xiaoyou thought it was her hallucination, but then the boy entered Xiaoyou's dream and told her that she could help him appear in the real world.
