How so?
Well..the plot is ok...It's slightly different.. And the chronicles of stories are also difference like in chapter 73.. Yoon yoo yoon flees from palace... After he left the palace his sister gives him in the hand of some bandits...then suddenly the general appears...save ukhe and gets injured then when they moves from there they notice that the crown Prince' soldiers are runnig after them the genarel tells ukhe to run alone..then the ukhe run away to another country with the help of a merchant...In this running process the '"ukhe never meets with the crown prince""..like they shows in manga that the ukhe "jump off" from the clif infront of the "crown Prince "... .
Well...the novel and the manga Doesn't match... It has quiet big difference!!
