The concubine Su Jinning married into the Xie Mansion on behalf of her younger sister, and married Xie Hengzhi, the marquis of Zhenbei who was framed and dormant. In the Hou Mansion, she dealt with Liu Ruyan's provocation and the old lady's temptation, and reorganized the general affairs with her ability. Later, she formed an alliance with Xie Hengzhi because of the common goal of revenge (finding out the truth about her father's death and redressing the Xie family).
Purpose: A concubine breaks away from the shackles of her birth, forms an alliance with dormant powerful officials, uses wisdom and courage to fight against machinations and conspiracy, wash away her grievances, stick to justice, and finally gain self-salvation and the warmth of walking side by side.
