Hatred?

Yu Seok finally had an answer that he was looking for when Elder Yoo slipped up and mentioned this last line. Quietly,he asked,"Why does Lady Lu hate Xie Eun? If it is just about the will then both are her granddaughters and if it is about gaining control then she could have just manipulated Xie Eun without the girl being none the wiser."

Elder Yoo however did not answer the implied question in the statement and instead asked,"Yu Seok?Are you not curious about the past? Are you not going to ask me anything about that. You have lived as an orphan in spite of having a family..I want to ask if you have been well. Have you suffered a lot? Are you not curious about your parents deaths?About your twin's life?Anything?"
