Shen Jingyi was tricked several times by her stepmother and father to make her a concubine for the King of Chu, but she was rescued by Wu'an Marquis Chu Huaixu by accident.
Shen Jingyi planned to leave the capital with her younger brother to seek shelter, but was surrounded by many people on the way. At the critical moment, Marquis Wu'an appeared and took her back to the capital.
Shen Jingyi simply ignored the two masters and agreed to marry Wu Anhou. The two of them each got what they needed. Wu Anhou helped Shen Jingyi deal with her stepmother and father, and Shen Jingyi helped him deal with the temptations of various royal forces.
Marquis Wu An was very wary of Miss Shen at first, but after seeing her being framed by her stepmother again and again, he felt a little pity for her.
After bringing her back to Beijing, facing the emperor's urging for marriage, he was worried that his future wife was an informant of several other forces, so he and Shen Jingyi proposed an agreement to get married.
