Yua Sakura is an ordinary middle schooler (soon to be high schooler) who loves to write and draw. She is a straight-A student, but that doesn't mean that she likes being one. She feels that she has a hole inside of her that she just can't fill. Her best and only friend, Shiro Aoi, has known her ever since they were little, so he knows everything about Yua. This duo still has a lot to learn about friendship, and who knows? Maybe Yua will be able to fill in that hole with the help of Shiro.
