One day, Yu Lin dreamed that he'd transmigrated into a book as a cannon-fodder shou. The dream shocked him so much that he was late for school the next day. What he couldn't figure out was why his classmate, his sworn rival and the top student in their grade, was late too.
Yu Lin thought transmigrating into a book was a one-off, but then he entered the book every night. He started being late every morning, and what shocked him even more was that his rival was late too. Why were the events in his dreams becoming more and more different from the book?
And why was the book's main shou becoming more and more like his sworn rival? Not only did they look alike, but they acted alike too!
