Hey, He and His Mortal Enemy Were Reborn as Twins.

In their previous life, they were loving emperors and empresses praised by both the government and the public. He controls the kingdom, and she manages the harem. Everyone knows that this is a match made in heaven. No one knew that after they stabbed each other to death, they all wanted to crush each other to ashes. Open your eyes again. Double birth, twins, dragon and phoenix. The same bed, the same set of dishes and chopsticks, crawled out of the same mother's womb. They were still smiling, still in love... Still waiting for each other to die first. He wanted to strangle her to death. She wanted to kill him. No one succeeded. No one will stop. They all have a common wish: In this life, you must die before me.
