You need to read original manga,temptation chapter 2. Story is completely altered. It will give you whole other feeling. You can catch the story flow, almost exactly the same as the show except the Ending!!! The producer made up all the bullshit story, that's not how it supposed to unfold. Akira is beautiful. So much so that he can have any girl... or guy that he lays eyes on making him very self-centered. Unfortunately, the only woman he has ever wanted is the one woman he could never have, his own sister. When he first met Kaname, naive to the ways of the world, his ownworld slowly began to change. The realization of the reality that his sister can never be his and that he can never find true comfort in her arms devastates him. There, from the depths of his despair, he finds salvation in Kaname's loving embrace.
