The Crown Princess Was Born to Bear Children

I was born with a body capable of bearing children, but because of my plump figure, my whole family treated me like a freak. My twin sister used her slender figure as an excuse to bully me like an animal, while my own parents treated me like a lowly slave. Later, my sister and I both entered the palace and married princes. The Crown Prince she married was frail from birth and unable to get her pregnant. But the Second Prince I married was virile, and we had two children in three years. Thanks to his children, he ascended the throne as emperor. My sister grew jealous, and on the day I was made empress, she burned me alive. When I opened my eyes again, I was back on the day before entering the palace. This time, my sister rushed to marry the Second Prince so she could become empress. I laughed. The Second Prince was actually the one who was truly incapable of having children. If my sister married him, not only would she never bear children, she'd also become a eunuch's plaything...
