Intro
On the day the Emperor returned from his expedition, a shockwave ran through the Imperial Court.
The Emperor, a man known to be ruthless and cold-blooded, who never opened his heart to anyone and was supposedly a stranger to the concept of love...
The person he brought back with him was a single, unknown woman.
The Emperor keeps her by his side, holding her hand and looking at her with a gaze more tender than anyone has ever seen. "Let no one lay a finger on her. She is my precious woman."
However, the Emperor already had a fiancée who was said to be the next Empress.
She was the one promised to stand by the Emperor's side, the one who was supposed to eventually become the Empress of the Empire.
Yet, the Emperor showed absolutely no interest in her.
He refused to fulfill even his duties as a fiancé, doting only on the woman he brought home.
A sudden romantic rival appeared just as the throne of the Empress was within reach. And a tyrant who might shake the very order of the Empire for the sake of the woman he loves.
