Plot
Eun-soo works conscientiously as a librarian in a seaside village. One day, she catches a mysterious man damaging some books at the library; the man, clad in a black suit with a black tie, tears out a single page from every book he comes across. At first, Eun-soo accuses him of book vandalism and reports him to the police, but she soon becomes curious regarding the complex story behind his actions. Joon-oh's girlfriend had suddenly left him with only a mysterious note, "Look up page 198." So Joon-oh goes to the library everyday and tears out page 198 from every book, hoping that he will find a message that might lead to his beloved or at least the reason for her disappearance. When Eun-soo checks the library database, she discovers that Joon-oh's girlfriend was a bibliophile, checking out a total of 956 books from the library. Eun-soo initially advises Joon-oh to let his ex-girlfriend go if that's her wish, because keeping trying to trace her is just an empty obsession. But since Joon-oh shows no sign of quitting, and she herself has just broken up with her boyfriend and is feeling her own loss in love, Eun-soo decides to help him decipher the messages on page 198 of all the books.
