She is a queen with a hidden demon body. She is gentle and quiet, and wins the emperor's heart. The emperor didn't know her true identity at first, but once he realized that she was a fox demon, he secretly planned to kill her. But after getting along with her for a long time, he saw that she was pure, kind and lovely, and her mind was clear. He had already fallen in love with her, so he secretly hid the knowledge of the truth in his heart and favored only one person. Later, a national crisis came, and the enemy's demonic forces caused trouble in the court and endangered the country. She took off her palace clothes, put on her armor and went into battle, fighting against the evil spirits on her own, and was seriously injured and dying. The emperor stayed in front of the bed day and night, never leaving, full of regret and love. When she woke up and opened her eyes, looking at each other, the Emperor's heart had already determined that she was the only one in this life, no matter the mundane or the monster, she was the one who was close to his heart.
