Updated (18/5/2007): Added music video of the 'Nada So So' song's Chinese version by Joi Chua.
NADA SO SO (TEARS FOR YOU) is directed by Nobuhiro Doi, whose previous film is the highly popular IMA AI NI YUKIMASU. Like that film (which, to me, really isn't as good as its vastly superior TV dorama series), NADA SO SO belongs to the 'Pure/ Innocent Love' (Jun-ai) genre, but different in a sense that it focuses more on sibling love than romantic love. Though obviously, it's still as much as a weepy tearjerker as the other films of this genre.
Just look at the poster above. Can something like that NOT be emo?
