Produced by Kakao Entertainment and airing on MBC, “21st Century Grand Prince’s Wife” has been described as MBC’s largest tentpole drama since its founding. Meaning, it is their biggest and boldest project yet. With a massive budget, high-end casting, and huge expectations, the drama is being crafted with a level of care and ambition rarely seen in Korean television.
Filming is currently taking place in Socho-myeon, Wonju (Gangwon Province), where an enormous 23,000㎡ set has been built exclusively for the series. Gangwon is quickly becoming a go-to destination for K-drama productions, and this project is expected to spotlight the region even more.
According to reports, MBC is putting everything into this production to the point that they even reorganized their drama division to handle large-scale projects like “21st Century Grand Prince’s Wife.” It’s not just a drama. It’s a statement of confidence in the global power of K-content.
A Modern Woman in a Royal World
The story follows a modern-day woman who gets entangled with a royal family in a fictional South Korea where a constitutional monarchy still exists. “21st Century Grand Prince’s Wife” dives into the world of modern royalty and high society, exploring the romance between a chaebol heiress and a prince who struggles to find his place in the modern world.
With IU’s graceful emotional depth and Byeon Woo-seok’s charismatic charm, the pairing promises a breathtaking mix of love, class tension, and self-discovery. It is a story about two people who redefine what it means to live freely in a world bound by status.
Set to air in the first week of April 2026, “21st Century Grand Prince’s Wife” is already shaping up to be one of MBC’s biggest dramas of the year — the kind that will make us swoon, cry, and rewatch again and again.
So mark your calendars, because April’s about to feel royal.
