This movie is based on incest. The first movie of my life which is out of the line. First romantic movie which involves physical and romantic relation between blood related siblings. In movie twins share a incest relation.
I just want to say that its not an ordinary romantic movie. And even in the ending they were going to separate. I just don't know when will their parents will get to about their incestuous relationship.
In the movie we just got to know that both brother and sister accepted each other physically and romantically about what about people, society and their own parents did they accepted them?
The consensual incest is legal in some countries including Japan.
And I think love never discriminates anyone!!!
