I feel sorry for Fu Rong, she's hurting the most because she doesn't want to doubt Duke Su but all circumstances doesn't support his innocence. And she has lost 2 loved ones. Also, she didn't do anything that will endanger Xu Jin. She just want to prove that her master did not do the killings. ?
I have no complain. I enjoyed this drama. Struggles, conflicts and misunderstanding are real. You just can't judge each characters thinking. Even in real life these do happened. Anyway, it's a happy ending. Looking forward for the extra (modern) episodes.
