Terriella, a princess was sold as a bride to the Emperor of Leonhardt. The Emperor, Livanfell, was known as the worst tyrant in history. But this man, he's weird at night. "The only one who can heal me is the princess. I need the princess." He unbuttoned his shirt. A burning desire was revealed in the flashing light of his eyes. 'Do we have to do this every night?' As if to relieve the extremely old thirst, the man endlessly longed for everything about me. And at the same time, many things surrounding me began to change. "I will protect the Empress." "According to God's will." I was the only savior of the perishing world.
