'Wife of a 21st Century Prince' teaser"

'Wife of a 21st Century Prince' is a romance about breaking social barriers and forging destiny, set against the backdrop of 21st-century constitutional monarchy in South Korea. It follows ‘Sung Heejoo’, a woman who has everything as a chaebol heiress but is frustrated by her commoner status, and ‘Lee Wan’, the prince who is the king's son yet is saddened by his inability to possess anything.

IU portrays ‘Sung Heejoo’, the capable second daughter of a chaebol family who possesses outstanding beauty, intelligence, and a competitive spirit, yet is constrained by her commoner status. Sung Heejoo is a bold character who chooses a contract marriage with Crown Prince Lee Wan (played by Byun Wooseok) to obtain the one thing she lacks: ‘status’. Meeting Prince Lee Wan, who shares a similar background yet made different choices in life, becomes a turning point for her.

Byun Wooseok portrays the sorrowful Prince Lee Wan, who possesses nothing but his royal bloodline. As the second son of the royal family, forbidden to shine or make a sound, he has lived suppressing his fiery heart. Yet, his innate grace and charm make him one of the ‘most beloved royals’ among the people. Accustomed to always hiding himself, he undergoes a new inner transformation upon meeting ‘Sung Heejoo’, his contractual marriage partner, who seems both similar and different to him.
