Hey there :3
I actually did not want to open a new thread for that simple question, but it didn't fit in any other thread (at least I didn't find such a thread).
I really like Romance Animes, but they're mostly Comedy (like Kaichou wa Maid-Sama). The most profound and deep Anime I watched so far, was Bokura Ga Ita, where many grave problems are shown. Do you know any Anime like Bokura Ga Ita, that is also profound and stirring?
