Inspired from Singderella variety show. I combine the classic Cinderella with Beauty and The Beast in some improvisation.  Hope you enjoy.  This is gonna be one shot with some part maybe. It depends on my mood.  LMAO.  But I will make it complete. 

Once upon a time,  there is a huge kingdom named Carpediem. The kingdom is so famous because their king and queen has a very handsome prince named Prince Kim Myungsoo.  But not only handsome,  he is also known as arrogant and cold-hearted prince, unlike his parents. They never treated people as their social status while Myungsoo always mock on ugly people. On his 20th birthday, the king and the queen prepare a very big party to celebrate it. They ask all the people from the entire place to join,  even the poor people. This is not only a birthday party,  but also the party to choose the bride for Prince Myungsoo. But something bad happen when an old poor lady who comes to the kingdom to join the party accidentally bump into Myungsoo and spill some drink on his shirt.  He was so angry and yelled at the lady with some hurtful words.  The lady was hurt at his words and suddenly something terrible happen.  To everyone surprise, she is the descendant of the witch.  In anger, she then curses the prince.  And some magic happen, in front of the people, Myungsoo's face turn so ugly,  his face now is more like monster making the people run in fear. 
Far away from the kingdom,  live a simple family with a father, mother and three sons in it. One of them named Lee Sungyeol.  Actually, Sungyeol only lives with his father.  Sungyeol's mother had died when Sungyeol was ten. Now, Sungyeol is seventeen and last year his father remarried a widow with two sons. So, from that day on,  Sungyeol lived with his stepmother and step brothers.  But unfortunately,  his new family is not very nice to him.  They only nice when his father was at home. His father is a servant in Carpediem kingdom. He rarely came home because of his duty. 
One day, Sungyeol's father is sick,  so Sungyeol replaces his place in the kingdom because none of his brothers willing to do that low and dirty job.
Out of his knowing,  fate has brought him a beautiful gift that will change his life forever.
