Like extra-dark chocolate, the bitter sweet love story is meant to be savored. I was a little disappointed that there was such an ambiguous back story to Fushimi, it appears that he ran away from home, or that's my impression, but the reasons why he felt he needed to were left vague. Also, it's not explained why his personality is so passively docile that he'll go back to the place he was raped, yet has the strength of will to run away from home.
