Mr. Gu, Please Stop Begging, I Won't Be a Substitute.

This is a misplaced love between a "white swan" and an "ugly duckling" whose identities are exchanged. Gu Zhixing thought that he was being backward compatible and saved a bird that accidentally entered the altar; in fact, it was Su Nian who broke its wings for him and was willing to be trapped in his palm. Many years later, when she regained her identity and came back as a capital tycoon and said to him, "Mr. Gu, you are well," he realized that some belated affection was worthless than grass.
