Inhwa, Year 14, when King Hyun’s (Park Chanhwan) illness worsens, the Queen Dowager (Kim Hyeja) orders Crown Prince Shin (Ju Jihun) to submit to an arranged marriage. Shin (Ju Jihun) proposes to dance major Min Hyorin (Song Jihyo), who he’s secretly dating, but she thinks he’s joking and refuses him, saying that her dream of becoming a successful ballerina is more important to her.
Meanwhile, Chaegyeong (Yun Eunhye) is an ordinary high school student whose family is in deep financial trouble because her father had been guarantor to a person who skipped town without repaying the loan he’d taken out. When the Royal Family notifies her of the arranged marriage, it throws her world upside-down. What the family had thought was a joke in Grandpa’s will was for real.
Shin has already accepted that as Crown Prince, his life is not his own. He agrees to marry ordinary high school student Chaegyeong in exchange for permission to live in Changdeok Palace and the reduction of the number of bodyguards he must have with him.
Chaegyeong happened to witness Shin’s proposal, and argues that an arranged marriage is ridiculous and illogical. Just then, debt collectors charge into her family’s house and start putting red stickers on everything.....
