Eun-Sae is thrilled when dreamy bookworm Kyung-Do asks her to volunteer with him to clean up their school library. Unfortunately, a couple of surprises await her as she takes on this new task. Though Kyung-Do is clearly interested in reading everything in the library's sprawling collection, he shows very little enthusiasm for actually organizing the place. Secondly, the collection includes a book with some sinister supernatural qualities that may have played a part in several tragic deaths, including that of Kyung-Do's father. Can Eun-Sae save Kyung-Do from meeting the same fate?
