Kaito has this protective nature of him to those who are closest to him since birth. And since he was gifted one Christmas eve a young angel, a little sister, before his mother died, he dedicated all his life to her. And as he grows into a young man and as he sees Yuna grows into a young lady, he had seen the most beautiful girl inside and out he ever saw in his entire existence. And as years pass by they live together, the sibship love has blossomed into a kind of forbidden love Kaito, a brother, shouldn't feel and do. A forbidden love, a sinful desire, yet the very sweetest sin Kaito has ever committed.
