It was good until Uto Keiya did such things to her. A 26 year old man loves a 16 year old girl! It would have been fine if she just met him on the road or mall or any place but a man who brought her up like a father and brother, it is unbelievable! I do not recommend you this anime. It has sexual content. Please don't watch. I don't know why did 3 million+ people wanted to watch this show.
