I'm Done Being a Second Wife

After my elder half-sister died of blood loss giving birth to twins, a boy and a girl, I became Pei Zhishi's second wife. I honored my in-laws and managed the household, doing everything I could to raise the frail twins to adulthood. That was until Pei Zhishi returned from war with a young woman who looked just like my half-sister. The twins had never once called me Mother, yet at their first meeting, they threw themselves into her arms and affectionately called her Mother. From then on, they were inseparable from her, and even my usually sharp-tongued mother-in-law showered her with praise. When Pei Zhishi wanted to take her as his co-wife, I refused, even at the cost of my life. The twins poisoned me to death. When I opened my eyes again, I was reborn on the very day Pei Zhishi returned. Holding the woman in his arms, he looked at me coldly. “I’m marrying Jia’er. Do you have a problem with that?” This time, I had no problem with it at all. I handed over both custody of the twins and control of the household, then turned around and married the crown prince, who had secretly loved me for years.
