This book is also called: "After breaking off the engagement, he tried his best to marry into my house" and "The Lady's Dog Training Diary"
The sinister young lady vs. The loyal dog, the little marquis
No one in the capital knows that the young marquis of the Zhaoyuan Marquis Mansion had to carry out ten family rituals in the ancestral hall in order to cancel the baby marriage that the old marquis had arranged for him.
Xi Jingxun hated the word "arrangement" the most in his life. When he knelt in the ancestral hall to write the letter of divorce, he never imagined that he would kneel in the Jinluan Hall with his fame and fortune to ask for a marriage decree.
PS: The male protagonist will change his surname later when he gets married.
