Need urgent spoilers for The Princess Wei Young

I am currently watching TPWY and desperately needs spoilers. Like how gradually the relationship in this drama evolves and how long can Wei Young outsmart the evil mother and step sisters before the story starts going around in circles. I am in episde 20 at the the moment and till now i love the plot and acting, but i constantly get the feeling that Wei Yang will turn into some noble damsel soon which my fierce feminine side is not prepared for. SO PLEASE SOME SPOILERS PLEASE!!
