"The princess is laughing at me?"
"My lord, please don't make trouble unreasonably."
"Princess, I need to rest."
"My lord, go."
"Shouldn't the princess serve the king?"
"If the prince is too full of energy and cannot vent it, why not ask the mother and concubine for instructions tomorrow and select two more girls to join the palace?"
"Presumptuous."
After regaining true form
"Emperor, did you fall in love with me at first sight?"
"No, it's not love at first sight, it's love at first sight. The first time I saw you, my heart fell on you and I can never come back."
