In order to save her younger brother, she sold her ancestral fragrant recipe to the emperor of Beijing, Mo Juechen. She thought it was just a deal, but he became addicted to her unique fragrance, which was the only antidote to his years of stubborn insomnia. "Your fragrance is mine, and your people are also mine." He kept her close to him, never leaving her. From a desperate deal to a cage called "love", she struggled and escaped, but she didn't know that behind the ice-tempered domination was his bone-burning love that was already terminally ill.
