The ugly duckling turned into a swan. The sow's foot is called Xia Keke.

Are you looking for a novel with Xia Keke as the heroine? A few years ago, I did read a novel whose heroine was Xia Keke. I don't know if it is the one you are looking for. The name should be "angel's promise" Mainly about four men and four women. The hero's name is Xia Ba, and the male number two is Ann, and the female number two is Lin Keer. I don't remember the rest clearly. I hope I can help you.
