I have a theory : when the heir of the Flanker family who is a little girl, fell in to deep sleep (don't know why), her soul went into Sia's body when the crown prince found her... she occupied it until the moment she died, that's when her soul came back into her real body which is the one of the Flanker heir. That's why when she was little as Sia she remembered the name "Freya" because it is the name of the heir of Flanker, her real name. Therefore, now that she got her body back, she still thinks of the name Freya, but she does no know that's it's the body's real name... I think the crown prince took advantage of the body swap, but I still do not know whether or not he is directly linked to it.... Can't wait to discover the truth!!!!
