I feel bad for the MC. I hope she starts being appreciated for herself and not as a medium of the consort. Her depiction of the consort's "concern" for him is not going to help him recover from his loss and only encourages him to continue yearning for what is gone.
well, they're gonna have to phase away the fake possessions pretty soon or else this story is going nowhere with the relationships. Looking into the murder of the former crown princess would be a start. Maybe once they solve that, the Crown Princess can be "at peace" and go away?
