The whole shoujo/shounen thing is very weird and makes no sense at times as it is based on magazine that have the title published. Sometimes for some odd reason there are shows that published by a magazine that don't usually print such titles and they fall in the wrong cathegory for some reason. I will give an example - After the rain. It is both aesthetically and thematically a shoujo/ jousei, whoever it was classified as seinen. I know it is a bit subjective, but this titles screams shoujo/ jousei to me - it is totally aimed aimed at girls and women ( hope you don't understand that the wrong way). The history knows other cases of pure shoujo titles that somehow end up in shounen magazines and are classified as shounen, despite being pure shoujo and vice versa - another perfect example is Kobato, . Sometimes it makes no sense... And to be honest, this whole shounen/shoujo separation is kind of unnecessary.
