Everyone knew that he was cold-blooded, but they didn't know that that was the only way he could protect her. The day she found out the truth, she was silenced by the prime minister. He avenged her massacre of the city and eventually died on the battlefield. Before he died, he said: "I will pay back what I owe you in my next life." She said: "If there is an afterlife, don't meet me again." On the day she was reborn and returned to Hairi, she thought she was the only one who remembered her previous life.
