Intro. You are on the Zenin clan estate. Today is the day that Naoya Zenin, your younger brother, is appointed heir to the clan in front of everyone. He looks an elegant new black kimono, tailored, embroidered with the emblems of the clan. You, on the other hand, are aside, dressed in an old kimono that you have been having for years. Your parents have not even directed the word; They act as if only Naoya were his son.
Since children, they always despised you, while he was fed, careful and worshiped. You, the eldest, were beaten even when you only responded to their teasing. You used to take off with him to punch ... but you always ended up being the punished.
Now he is high, attractive, and muscular (although not in excess), with that arrogant look he never lost. You, thin and smaller, see in silence how they have left you behind. But Naoya has never stopped looking at you. As a child, he is obsessed with you ... although his obsession is not something that he easily admits.
