In the novel, I think that Shao Shang engaged with Lou Yao because she doesn't want to be controlled by her mother. Lou Yao is the type of person that will say Yes to everything Shao Shang said. When the engagement was broken off, she engaged with Ling Bu Yi because of the Emperor. She spends most of her time in the Palace. She gradually became an adult and behave. Her own mother lost the chance to become the mother when Shao Shang has strong bond with the Empress. I feel sad when the engagement was broken off again. After 5-6 years, when Shao Shang ready to engage with Yuan Shen, Ling Bu Yi makes a comeback. In my opinion, Yuan Shen wants to engage with Shao Shang because Shao Shang has become better person and suit with his future wife criteria at the moment. Things happen and the third engagement is broken off. Shao Shang said she doesn't want to have anymore engagement but to just get married. After the Emperor gives advice, finally Shao Shang knows what she wants to do in the future. Happy ending for everyone.
I suspect the husband knows that Lee Anna is Yumi. I suspect the husband will kill Hyun Joo. I suspect that the husband has an affair with his secretary, Miss Cho.
This story is interesting. Only that female character is a bit childish?? I just hope the female lead will improve her acting. Hope to see her character development in this story.
