Li Fangzheng is a man with a treacherous heart but no courage. He is still the same even after traveling to the era of Emperor Lengquan of Japan. On the surface, he is sanctimonious and cautious in his words and deeds, but in fact, he maintains his image because of his timidity. Originally, he might have died of old age like this, but an affair with his wife changed his life. He actually fell in love with the adulterer, Mr. Genji.
