this anime can be describable in one word... SHOCKING you know watching every episode builds up the tense and romance between the relationship of each and every characters especially the protagonists hiroki and elis... every episode not only the protagonist's personality but as well as the deuteragonists and the supporting casts... you wouldn't know WHO will end up with WHOM... and also they did a great job hiding hiroki's true feelings...eventhough i find it a little bit of incest it kinda gave me an impression that hiroki and elis aren't just siblings... they give off an aura of lovers rather than relatives...
