Rebirth: Back to the past

[First person point of view] Where Am I? Where is this place? No, this historical dress, don't tell me that I have travel back to the past... no, this can't be. I'm just a teenager. "You will married to the crown prince on behalf of your sister" I have to married a guy that no one see a face of nor have we heard of? I kind of joke is this? If the emperor can't even see his own son face then how am I supposed to know who he is? I need to find a way back home... There must be something that can bring me back to my real time line, I don't belong here.
