Al and Milo are classmates and childhood friends who are neighbors. While Milo is straightforward and honest, Al is carefree and it's hard to tell what he's thinking. However, strangely enough, the two of them have always spent time together. They go on a journey without knowing where they're going, and the destination is a place they visited with their family when they were young.
