Set in a 21st-century constitutional monarchy in Korea, ’21st Century Grand Princess’ portrays a romance where Seong Hee-joo (played by IU), who has everything but is limited by her commoner status, and Lee An-dae (played by Byeon Woo-seok), the king’s son who has nothing, overcome their social statuses.<\/p>\n

Global fans’ anticipation for the chemistry between popular actors IU and Byeon Woo-seok is rising, leading to high pre-broadcast buzz.<\/p>\n

Kakao Entertainment plans to enhance the drama’s quality by directly planning and producing the OST.<\/p>\n
