Anime has the tendency to make the audience feel sad, excited, happy, and even satisfied with its vast collection of spectacular stories. However, some stories are so ahead of their time that they don't seem to resonate the way they should with a certain age group. Some anime simply hit differently when re-watched as adults, and Orange is the type of story that can morph itself according to the audience's state of mind. It's almost criminal to label Orange simply as a romance anime. Love is one of the themes explored in the series, but it's the least important one.
