The Su sisters, born to the direct line of Sterling Manor, have competed in all matters since childhood. Years ago, the younger sister mistakenly took her older sister's marriage contract, married into Gresham Manor and became Elspeth Gresham. After years of marriage, she and her husband maintained a respectful but distant relationship, until Gresham Manor planned to take the daughter of the enemy who drove her birth mother to death as an Honored Concubine, at which point she fully saw the coldness of this marriage. Her older sister, who had long prepared a mutual divorce agreement, came to her and said "let's get a mutual divorce", which made her fully determined to leave Gresham Manor. The two sisters left the manor with half a carriage of books, opened Jade's Academy in the Imperial Capital, and exclusively taught women who had no way out. At the Full Moon Banquet for the young son of Gresham Manor, someone publicly presented evidence that the Lord of Gresham Manor had a natural fertility problem, which made Gresham Manor lose all face and become the laughingstock of the entire city. Afterwards, her ex-husband repeatedly begged outside the academy for her to return, but she always refused to meet him. She once thought that marriage would give her lifelong support, but now, with her own hands, she has become the support of countless women.
