Hidden Love (English Ver.)

In the Duke's mansion a daughter born to anyone but the official wife lives on whatever the official wife allows her. Li Chuchu was born that way and has spent more than ten years under it. Her birth mother is dead. When things turn against her she finds out that the death was arranged and that someone was behind it, and she begins working toward paying that back. The one other person in the house asking the same question is Li Zhen, the official wife's son and her half brother, and what runs between them holds love and hate and a fixation neither of them acts on. The two of them look for the truth together.
