Li Mo Ran was the fourth son of the Duke of Anguo, born to a concubine of the Duke of Anguo. Although he was concubine-born, due to his good looks and intelligence, he was greatly favored by the Duke of Anguo. However, he had a deep affection for his brother-in-law, Prince Jing Zhao Yuanxian.

To assist Prince Jing in securing the throne, he agreed to the plans of the Duke of Anguo and Prince Jing, and married into the Crown Prince's residence to steal information. Unexpectedly, after Prince Jing succeeded in taking the throne, he heartlessly said, "If this palace accepts you, wouldn't it be a joke?"

Directly dismissed with just two thousand taels of silver and a separate estate, he spent the last years of his life alone. In his final moments, he regretted everything and wished he had returned the love of the man who had given him his heart.

When he returned back in past, to the moment he was born, he was determined to fix everything this time.
