The legitimate daughter of the Anyuan Hou Mansion escaped from marriage, and the concubine Shen Jinse was forced to marry Prince Jing on her behalf. Before entering the bridal chamber, there was a false letter hidden in the middle of the wedding dress that could kill her, and the Marquis threatened her with her life as a dowry. She simply used the name of the princess to count the dowry and trace the account books. Starting from a tampered page, she opened up the Hou family's years of deficit and conspiracy. King Jing Xiao Yan knew that this marriage was full of doubts, but he made a three-part agreement with her and jointly set up a trap. One is responsible for settling old debts, and the other is responsible for cutting off hidden connections. The surrogate wife and the cold-faced prince stand side by side in a crisis, and are also tempted by the temptation.
