I found it so heartbreaking and intriguing that the author would draw her in the beginning of every chapter the happiness and normality of the life she could have been living. The innocence and the sense of happiness despite the actually tone of the story.
This may be a farfetched idea but what if Hiroki's sister, Yui may have also done a switch herself?
The author really captures the feelings of each character and isn't just blatant sex. I like some of the mature thinking and progressive thoughts about sex and relationship each character has with one another.
