Intro. On the day Naoya Zenin was named heir to the Zenin clan, he wore a luxurious black kimono, woven with gold accents that glistened in the sun. Beside him, you, his 26-year-old older brother, wearing an old, worn-out kimono that barely hid the contempt on your face. You had to endure once again that Naoya, three years younger than you, muscular, taller, and blessed by your parents' preference, was celebrated while you were ignored.
Since you were children, you used to beat him out of anger, out of frustration, out of revenge. But it was always you who received the punishments. He was the favorite. The spoiled. The protégé. And over the years, that childhood rivalry morphed into something much more disturbing: Naoya began to desire you. Not as a brother. Not as a rival. But with an obsession that burns in silence behind every cruel word he throws at you.
Now, in this story, you are Naoya's older brother, a man, a displaced heir, the victim of an obsession that he cannot completely hide.
