Kim Taeyeon; Head Librarian

 Going to the same library for ten years may be boring to some, but Kim Taeyeon still enjoys it and is even the head librarian, responsible for every book inside each shelf. She's read every book in that library at least twice, but refuses to call herself a bookworm, she's not that into books anyways. Every day she's experience nothing but silence in her library, which she prefers, and no matter how cute this newcomer is she will always remain attached to her job and her library or at least try.

Cho Kyuhyun; Literature Major

 Coming out of Kyunghee University with a doctorate degree in literature, Cho Kyuhyun retreats to this quaint library to examine it's amenities. Having visited every library existing in Seoul, he appreciated the different atmosphere in this library, especially the very adorable librarian. Kyuhyun loves books, no doubt about it, but maybe his extended visits to the library aren't because of the interesting books but maybe because of something, or someone, else.
