A high school student, Liam, has been in love with his fellow classmate, Heather, ever since they met in the second grade. But as the years past, he begins to believe that Heather is drifting away, and there is nothing he can do about it, believing that she left him behind. It's now high school, and Liam distances himself from people, especially Heather, living in everyone's shadow..... But things change when he starts to lucid dream, dreaming about Heather. But aside from their similar appearances, this 'Dream Girl' is different somehow.. And it's not that she's dreamy. As the story progresses, Liam and Dream-Heather devise a plan to get to the Dream Library (a place where all dreams of people are made and kept), and find Heather's Dream!
