Tsk, My Archrival and I Were Reborn as Twins

In their previous lives, they were the loving emperor and empress praised by the entire court. He ruled the realm, and she managed the inner palace. Everyone said they were made for each other. No one knew that after they killed each other, they both wanted to grind the other’s bones to dust. Then they opened their eyes again. Both reborn, as twins, a boy and a girl. The same bed, the same bowls and chopsticks, born from the same womb. They still smile, still love each other... and still wait for the other to breathe their last first. He wants to strangle her. She wants to kill him. Neither has managed it. Neither will give up. They share one wish: in this life, you have to die before I do.
