Let's role to some preview of this drama!!!
The series starts off with the news that the King, Shin's father, is very ill. With the grim outlook on the King's health, the royal family scrambles to find a wife for Shin, so as to allow him to take over the royal throne if the situation requires. Despite being in love with another girl, the ambitious and talented ballerina Hyo-rin whom Shin initially proposed to (she rejects him to pursue her ballet dreams), Shin eventually marries a commoner to whom he was betrothed by his late grandfather in an old agreement with the girl's grandfather. Shin marries the headstrong yet lovable Chae-kyeong after Hyo-rin's rejection. Despite initially feeling nothing for Chae-kyeong, love eventually blossoms between the couple as time passes.
Portrayed by Yoon Eun Hye, Shin Chae-kyeong is a very creative and outgoing, normal high school girl. She attends the same school as Lee Shin, the Crown Prince of Korea. Her grandfather was best friends with the previous King. To honor his friend, the previous King dictated that Chae-kyeong is to become the Crown Princess, which means that she is to marry whoever is the Crown Prince at the time of the marriage (Lee Shin)
Lee ShinThe crown prince of Korea, Lee Shin, as portrayed by model and actor Joo Ji Hoon, is seen as a smug, indifferent, insensitive young man. After getting rejected by his girlfriend when he proposes to her, he decides to go along with his elders' arranged marriage with Shin Chae-kyeong. At first, he was irritated by her naivete and enthusiasm, but as he recognizes how genuinely sweet she is, he begins to open his heart to her, and falls in love.
Throughout the series, it becomes obvious that inside, he is just a lonely, sensitive, warm and kind young man. He also owns a teddy bear, Alfred, the only thing that he can let his guard down for, which is used as a focal point throughout the series. As his cousin re-enters the picture after being forced out of the country many years earlier, the prince quickly butts head with him, as Lee Yul is a contender not only for the throne, but for the crown princess Chae-kyeong's love. Chae-kyeong does not realize this until later on in the story.
