Reincarnation.
Unable to accept the emperor, who is engulfed in obsession and madness, I killed myself. But a hundred years passed by and I was reborn, as if it was fate, as if fate played tricks on me, and with my past memory intact at that!! I vowed never to see him again, but I hoped that at least he would’ve forgotten all his memory. Could I not have escaped him even with death. I face the reincarnation of the emperor once again.
