O Diabo Preto e o Príncipe Branco

This is like a less explicit 50 Shades of Grey mixed with a japanese "love-triangle"-school romance. Basically you have two guys with opposing characters battling over this one cute girl, who is way too eager to accept the advances of both of them. While ordinary japanese school romances are wholesome and deal with love and relationships, this movie is just obviously sexual. One of the guys calls her his slave and dog and wants her to do "submissive things". It's not as bad as any American movie in a sense that things are only implied here instead of shown, but I still found it off-putting. And the story itself is absolutely boring too.
