Cheng Yan traveled back in time and eventually ended up in Europe during the Middle Ages, becoming Roland, Crown Prince. 

But this environment does not seem to be the same as his old world. Are witches real and can they really use magic?

 Follow Rolands in his battle for the throne against his brothers and sisters. 

Will he be able to win, even though the king has already declared him hopeless and thus put him in the worst situation?
