IU and Byeon Woo-seok's Irresistible Charm Shakes Up 21st Century Korea in '21st Century Grand Prince's Wife'

IU and Byeon Woo-seok captivate audiences with their undeniable charm in the upcoming MBC drama '21st Century Grand Prince's Wife', set to premiere on April 10th at 9:40 PM.

The main teaser for the drama introduces the beginning of a romance that defies social status between Seong Hee-joo (played by IU) and Lee An Grand Prince (played by Byeon Woo-seok).

The teaser opens with Seong Hee-joo confidently proposing to Lee An Grand Prince, "Will you marry me?" Her bold self-promotion, highlighting her education, resilience, and capabilities, along with her status as a commoner, leaves Lee An Grand Prince with no choice but to accept, saying, "I can't refuse."

As Lee An Grand Prince instructs, "Prepare to become the Grand Prince's wife," the couple shares romantic moments, walking hand in hand under the spotlight and dancing a waltz at a banquet, exuding a genuine couple-like atmosphere.

However, opposition to their marriage arises, heightening the tension. Prime Minister Min Jeong-woo (played by Noh Sang-hyun) pleads with Lee An Grand Prince to distance Seong Hee-joo from the royal family, while Queen Dowager Yoon Yi-rang (played by Gong Seung-yeon) urges Min Jeong-woo to exercise his veto against their union.

With influential figures like Min Jeong-woo and Yoon Yi-rang opposing the marriage, a challenging journey is anticipated. Yet, the faces of Seong Hee-joo and Lee An Grand Prince reveal a growing excitement as they gaze at each other, promising a strong marital chemistry despite the obstacles.

Through its main teaser, '21st Century Grand Prince's Wife' hints at the inevitable clash between Seong Hee-joo and Lee An Grand Prince, who choose marriage as a means to overcome their destinies, and their adversaries, Min Jeong-woo and Yoon Yi-rang. The drama raises curiosity about whether Seong Hee-joo and Lee An Grand Prince can successfully marry against the opposition from the government and the royal family.

Even before its premiere, '21st Century Grand Prince's Wife' has generated significant buzz, ranking first in community response and second on social media in the TV-OTT drama category according to the FUNdex popularity index released by Good Data Corporation for the third week of March 2026, marking it as one of the most anticipated dramas of the first half of 2026.

Set in a 21st-century constitutional monarchy in Korea, '21st Century Grand Prince's Wife' tells the story of a wealthy woman frustrated by her commoner status and a prince who, despite being the king's son, is saddened by his inability to possess anything. The drama premieres on April 10th at 9:40 PM.
