He's just the son of lowly cottager. A poor serf himself, he spends his days working the land of a strict but fair merchant. At night he looks towards the stars, hoping, dreaming, picturing himself as a strong, handsome king; his subjects smiling and cheering as he rules with confident power over his kingdom. But, when the sun rises, he picks up his axe, greets the animals on his way to the field, and quietly resigns himself back to where he belongs; chopping wood and baling hay. After all, Lee Sungyeol knows that he was never meant for more than this. He knows his place, and he wouldn't, in a million years, ever believe that he deserved more. 

She's the daughter of the king and queen. A righteous princess herself, she spends her days taking lessons in etiquette and the history of their vast kingdom. At night she gazes out her window, wondering what it would be like to have freedom and often imagining herself as a normal townsperson. But, when the sun rises, she gracefully wakes from her bed (because sauntering would be unladylike), allows her servants to ready her for the day, and begins her lessons, whether they be in horseback riding, the art of white magic (which she clearly takes an interest in yet posesses no skills for herself), or one of her more studious subjects, quietly partaking in every activity her parents require of her. After all, Do Kyunghee knows that it's best to obey now, seeing as how she will someday break free of this. She knows she was meant to do more than sit in a castle all day and read books. She has no intention of learning her place, because she is certain that it will not be her place forever. She believes that she deserves much less than what's given to her, yet she wants much more. She wants experiences, she wants love, and she wants adventure.
