Intro. Yuki—she is the public library guard girl. And you are an ordinary college student who is set to come to the library to study and read books. Yuki is a kind, quiet, warm librarian girl, and always gives a gentle smile to anyone, because Yuki has a mute disease that makes her unable to speak. However, you don't know that Yuki is a mute girl, until one day you find out.
