Crown Prince Yi Gang grew up in the palace, surrounded by suspicion and betrayal. He is devasted by the death of his mother when he is young, and more recently the suicide or his wife, the Crown Princess. And he is sure that his wife’s death was not the suicide they are claiming.

When Yi Gang meets a peddlar in town who looks exactly like his late wife, he is shocked and confused. And he is secretly thrilled when she takes a job posing as a eunuch in the palace. And when an accident causes them to swap bodies, they are both desparate to return to their own lives. But fate has another lesson in mind that will allow them to see life through each others’ eyes and find a new perspective and respect.

Crown Prince Yi Gang is cautious and distant. He has very few people in the palace he can actually trust. And losing his wife only made that loneliness more pronounced. But swapping bodies with Dal I forces him to open up in ways he might have never done otherwise. And slowly he learns that she is trustworthy. Kang Tae Oh has such a magnetic screen presence, and I enjoyed the way this role let him move between serious and sullen and silly and joyful. I loved him in this role and I thought he was a great fit for the character. 

Park Dal I is a traveling merchant before a chance encounter with a mysterious stranger takes her on an unexpected adventure. She soon finds out the stranger is actually the Crown Prince, and she ends up following him back to the capital to work as his eunuch. But a random accident leaves her waking up in the Prince’s body, and he in hers.

Now she spends her days doing the job of a Prince, and getting to know the dangers and frustrations he faces on a normal day. And as she helps him investigate the deaths of his mother and his wife, she finds out that she has a much more personal connection to life at the palace than she had ever imagined. And together they begin to reveal the thread of fate that has bound them together and brought them to this point.

Park Dal I  is bright and cheerful. She works hard and maintains a positive outlook on her life and family. But she has no idea that she was once the Crown Princess, married to Yi Gang. And that most of her early memories are built on lies told to her by her family in an effort to protect her royal identity. Kim Se Jeong is a fun actress with a gift for exaggerated movements and gestures that make her great in comedic roles. Whether she is playing the quirky peddler or the woman trapped in a Prince’s body, she was a great fit for this part.

Yi Un is a cousin of the Crown Prince. At one time he had stood as an heir to the throne. But after his mother is accused of treason and “killed”, he is forced to leave the palace and fend for himself. But rather than compete or act jealous toward Yi Gang, Yi Un acts as a friend and ally in the Prince’s quest to root out the corruption at work within the palace walls.

Kim Han Cheol is a minister and advisor to the King. But he has gathered secrets against all the most powerful men in the palace, including the King himself. And Han Cheol uses those secrets to blackmail his competitors and garner more power for himself. Han Cheol is driven by his greed and the need to avenge the mistreatment of his first love, Yi Un’s mother.

Kim U Hui is the daughter of Han Cheol. She met Yi Un when they were young and fell in love with him. But her father intends to make U Hui marry the King so that he can use her position to gain the last piece of power he has not been able to take from the King.
