Not rlly coz u can sign a contract for a drama but it doesn't mean they have to film straight away. The director only follows yang zi so might happen in the future?
I know with whom yang zi ends with but don't know other information anybody mind to share a glimpse of her life…
As a child while running away from her grand mother she discovered she could change faces so she could escape her grandmothers guards while they were searching for her so while doing so she changed herself to a guy in order to protect herself and avoid being victim of kidnap etc. Over time she forgot how her true face looks like so she stuck with her guy face.
