Sisters Swap Marriage

I was a concubine-born daughter of the family, always looked after by my legitimate elder sister. In my past life, she married the Prince Regent—cold, distant, and incapable of intimacy. She spent her days in misery and died of heartbreak. I, on the other hand, married a top scholar from a poor background. He disliked me for being vulgar, and I disliked him for being pedantic. Our marriage was a disaster. In this life, both my sister and I were reborn. My sister asked, “Want to swap?” I didn’t hesitate. “Alright!”
