My Transmigrated Half-Sister Insists on Switching Marriage Partners With Me

[Both leads are romantically inexperienced] [Household intrigue] As a concubine-born daughter, Zhou Yunjin follows the rules and asks only to live out her life in peace. At her legal mother’s arrangement, she becomes engaged to her cousin. But after her elder half-sister is rescued from drowning, her personality changes completely. When she hears that her fiancé, the heir to the Marquis of Ding’an, has a six-year-old son, she refuses point-blank to marry him. Then she happens to catch sight of Zhou Yunjin’s handsome, dashing fiancé and falls in love at first sight. She insists they switch fiancés. As a lowly concubine-born daughter with no say in the matter, Zhou Yunjin can only agree. She resolves to be dutiful and keep her head down after marriage. Surely life can’t be too hard. After marrying, she does keep her head down, but the heir to the Marquis of Ding’an, Gu Tingwang, grows more and more attached to her. Zhou Yunjin: “My lord, the rules come first.” Gu Tingwang takes her soft, delicate hand. “In my heart, A Jin comes first.” Much later, the stepson her half-sister despised is revealed to be the pampered young Crown Prince. Her half-sister regrets everything. “I was the one who was supposed to marry your father! I’m your rightful adoptive mother!” The young Crown Prince’s face turns cold as he takes Zhou Yunjin’s hand. “She is my adoptive mother. How dare you insult her? Take her away and give her twenty strokes of the cane!”
