"Prepare to become the Grand Princess."
About
"Prepare to become the Grand Princess." Set in a 21st-century constitutional monarchy in South Korea, this drama depicts a romance that defies fate and social status. It follows a woman who, despite being a chaebol with everything, is frustrated by her status as a commoner, and a man who, as the King's son, is saddened because he can have nothing. Based on the premise that Crown Prince Munhyo, son of King Jeongjo, survived to succeed the throne, the story unfolds in a world where the constitutional monarchy has continued since 1945 without the Japanese colonial period or the Korean War.

After his older brother passed away in a mysterious accident, he took charge of state affairs on behalf of his five-year-old nephew. Nicknamed the '21st Century Grand Prince Suyang,' he is highly popular for his outstanding looks.
