Heartbreak Library

One day, Eun-Soo, a librarian, sees Jun-Oh 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.
