If we could count the little sins that lead us to a strange situation, on Tamaki Yukiteru's account overflow from his childhood when he accidentally burns down his house. He currently lives with the family of Yuno, her neighbor and childhood friend, who wants him "crazy", but he doesn't sense this kind of "like". But secretly dates Saotome Rena, a friend of both, who recently moved to their High School. It would be great if Yumeno Kaori, classmate, had not discovered this secret relationship at Yuno's eyes, and cause a silent pact with Yukiteru-kun somewhat peculiar. . . And the list of small sins does not seem to stop there.

So is a fault on genre on the tragedy part - it must be clear and put the label -, so more the yandere part must put on it too, 'cause isn't a simply sex - ecchi -, so harem plot here. If you hope that it could make you have a disappointment. And don't hope any HE.

This seinen is guided into a tragic conclussion, so the sex plot have an important rol on it, also the issues to manage a no sane near relationship since childhood, so many secrets on life, I mean on Yukiteru's weakness, so simplicity and the way he drives his own life and relationships.

And each character main or secondary have their own dilema so issues. The plot go more difficult ahead till ending.
