SynopsisOne day, Eun-Soo (Eugene), a librarian, sees Jun-Oh (Lee Dong Wook) tearing off a certain page of several books and accuses him of vandalism. Soon, she discovers that there's a complex story behind his actions.
It occurs that Jun-Oh's girlfriend, who was a bibliophile and checked out books regularly at the library, had suddenly left him with only a mysterious note that says 'Look up page 198'. Because of the strange note, Jun-Oh goes to the same library and tears out page 198 from every book he comes in touch.
Seeing Jun-Oh's despair for not knowing why the woman he loved had left him, Eun-Soo starts to help him find the hidden message on page 198.
