yeah but Joanna didn't do anything. She didn't expect to get pregnant and she was sure as hell not going to tell mark. It was Ou Wen who convinced her to tell Mark. Ou Wen decided to take a step back first in order to let mark make a decision and save both of them from too much pain in case the decision was to be with Joanna. That just shows how much Ou Wen loves Mark, he is willing to put himself second in order to do what he believes is best for mark.
I saw a wedding somewhere who gets married Shang Gu and bai jue or Hou chi and Qing Mu. Also I saw he gets married to another girl why? and how does it get resolved? One other thing shangu/hou chi gets pregnant?
I also don't think new guy will be an issue...they wouldn't make it an issue so late into the drama. We only have like 5 more episodes to go.
