She is the eldest daughter of the General's Mansion and has unparalleled resourcefulness. However, in order to find out the truth about her mother's death, she married into the Eastern Palace on behalf of her twin sister. On her wedding night, she was caught disguised as a man - it turned out that the person she was going to marry was not the prince, but the prince's new "male concubine".
He appears to be a sickly prince, but in reality he is King Shura who has been dormant for many years. She thought he was plotting against her, but she didn't know that this substitution marriage was actually his game.
When she wears the mask of her sister and becomes his crown princess as a man; when he looks into her eyes and says "I know who you are" - in the game of two powers, whoever is tempted first loses.
Later he knelt in front of her: "Please, look at me again."
She said: "Your Highness, I am a man."
