The Emperor Can't Sleep

"Thy revenge is just. Luke Allfenster..." Despite returning to the past, Chloe Langsher decided not to change anything. But as she waited for her destined end, her knight came before her. “He won’t be able to kill you so make him think you're already dead.” She faked her death and fled, led by her knight. She believed that after all of this, there would no longer be any obstacles in her future... “Your life is mine.” Even God could have not guessed that we would meet again, him as the emperor suffering from terrible insomnia, and me, the unfortunate pharmacist who prepared his sleeping pills.
