Fake Princess...
Lee Chang-You remembered the day of her confession.
[Wang Hui: "Chang, I like you. Will you be mine for this lifetime?"]
[Lee Chang-You: "Hui, I have started liking you too, since the day I saw you for the first time. I will be yours not only in this lifetime but in every life when I get birth in this universe."]
At that time, Wang Hui was the prince in the heart of every female artist of the Sky Imperial. However, the prince couldn't be with everyone, he could only be with his princess.
When Wang Hui confessed his love to her, she thought she was his princess.
When she became pregnant, she was so happy. She had a child in her womb which was the result of their love.
She thought now Wang Hui would accept her in front of the world that she was his princess and now on, other women couldn't keep their eyes on her prince. Now she would be his one and only princess.
