My Daughter Wants a New Mother? Fine! I’ll Marry the Crown Prince—cry About It If You Want

[Husband fakes death + real and fake daughters + two branches of the family + multiple identities] "You killed Father, you don't deserve to be my mother! I want to be adopted by my aunt!" My daughter screamed, clinging to my deceased husband's coffin. I fainted from heartbreak. But then I overheard my deceased husband and sister-in-law talking. "It was clearly your elder brother, Gu Jinnian, who died. You faked your death to marry me, don't you care that she died for you?" "If she weren't the legitimate daughter of the Shen family, why would I marry her? My heart only belongs to you and Xin'er." My sister-in-law sighed, "Poor thing, she doesn't even know that Xin'er is our child, and her own daughter is just a servant in the mansion." My husband chuckled indifferently, "She loves Xin'er the most. If Xin'er insists on being adopted, she'll be reluctant to leave and will come to take care of her. Then I can have two branches of the family, wouldn't that be wonderful?" Outside the door, my heart was breaking. So, he faked his death, he had an affair with my sister-in-law... They even used an illegitimate daughter to steal my own flesh and blood! What a despicable couple! I swear I will not rest until I avenge this! Want to be adopted? You ungrateful wretch, I'll just give you away. I'll turn around and find my own daughter, and make her a princess! Want to inherit a branch of the family line? I'll marry the sickly, disfigured crown prince to bring him good fortune, shattering your pipe dream! But on our wedding night, the crown prince removes his mask. That face... it's exactly like my deceased elder brother, Gu Jinnian...
