After transmigrating into a book as a cannon-fodder daughter born to a concubine, I married the coldest living King of Hell in the capital. No one knows that the supposedly heartless man is the older boy I've been searching for for ten years. But he has forgotten me. The boy who once promised to protect me now looks at me like a stranger. He guards against me and tests me, yet his eyes turn red when my life is in danger. Then he finds the jade pendant I've treasured and asks in a trembling voice, “How did you come to have this jade pendant?”
