The difference from the original drama is that Dajun and Yinlu are together instead of Jidong.
It is said that the first male lead in Korean dramas is used to develop the plot, while the second male lead is used to be liked. I think this drama is also like this. I like the Maharaja so much, so I wanted to make him innocent (haha, that's a bit exaggerated), so I came up with this novel.
