Before entering the palace, Gu Bai and Ye Zimo became good friends. Gu Bai was sent to the palace by his mother disguised as a man and became the little prince's book boy.
Many years later, the little prince knew that Gu Bai was born as a girl. He held her waist and pointed at Ye Zimo and asked, "Who is he?" She answered truthfully, "A friend I met before entering the palace." The little prince sneered, "Friend? I don't believe it." Gu Bai kissed him without saying a word. Many years later, the little prince hugged Gu Bai and acted coquettishly, "I actually still think he is not your friend. Just kiss me once..."
