Characters:

Prince Haechan - A noble Crown Prince of the Kingdom of Neo, son of the Great King Taeyong. He was forced into an arrange marriage that he despise the most. Maybe because he's straight and he doesn't like the idea of getting married to another Prince from the Kingdom of N City.

Donghyuck - A pauper who lives outside the Kingdom of Neo. He lives with his father, Yuta, a citizen of N City. Donghyuck lived in a poor neighborhood where they considered themselves a thrown out from the two kingdoms just because they didn't pay their taxes. Despite being treated like this, Yuta and Donghyuck stood strong together and used their skills for living.

Prince Mark - The Crown Prince from the Kingdom of N City. He is the son of King Youngho from a surrogate mother. After witnessing the marriage of his father and step father, Prince Ten from Dream Kingdom, the royal couple wished that their son will do the same thing to the Crown Prince from the Kingdom of Neo so that the two Kingdoms will unite as an empire.

King Taeyong - The Great King of the Kingdom of Neo. He was known as the greatest king among all kings due to his stern leadership, strict rules implemented and wars that he won multiple times. Everybody feared him due to his image but he's kind and humble inside. He had an agreement with King Youngho that they will make an arrange marriage for their sons to make the two Kingdoms powerful and modern.

Yuta - A pauper who originally came from N City. He was born as a rich business heir in N City until their business got bankrupt and forced to live outside the Kingdom. When his parents died due to illness, he was forced to live alone and find stable jobs from the Kingdom of Neo. Unluckily, he was kicked out due to his unknown status. Doyoung and Jaehyun, a couple who had the same fate with him, saw him and helped him make a living by working as a con artist.

King Youngho - The King of N City who implemented the modernization in his Kingdom. He was known as the cool King who used his brain in making his Kingdom a city and technology-centered. He also adopted the same marriage in his Kingdom, making him the first King who got married to a Prince.

Prince Ten - The Prince consort of N City. He serves as the mother figure of Mark as he raised him like his own son. He was originally from the Kingdom of Dream who lived as a King advisor before he became a Prince.

*This is based from Mark Twain's The Prince and The Pauper story but of course, this is a fanfic and everything can change.*

I'm back at writing another Markhyuck-Yutae centered fic. The very first Royal AU I've written in my life. I ended almost all of my fic just to make this one. The only on-going fic for now are Mission Abort, Lucky Seven and this one, which I will focus on. I planned on writing this plot a long time ago in my head and glad that I can finally put it in real writing.

I hope you don't expect much on this fic. I'm still a ty writer. But I hope you will like this too.
