Wife of a 21st Century Prince is an upcoming South Korean romantic drama that reunites IU and Byeon Woo Seok, marking a full-circle moment for the pair after nearly a decade.

Now, they take center stage together in a story that blends royal lineage with contemporary romance.

Controversies & Rumors:
Production Delays
Although initially announced in December 2024 with a tentative release date of late 2025, industry insiders have reported that Wife of a 21st Century Prince may now be pushed to 2026. The reason cited is scheduling conflicts among cast and production members, as well as ongoing negotiations over international streaming rights.
Casting Rumors
In early 2025, rumors spread online claiming that both IU and Byeon Woo Seok had quietly stepped down from the project due to creative disagreements or conflicting schedules. These claims sparked panic among fans and speculation in entertainment circles. However, both actors’ agencies swiftly denied the rumors, stating that their involvement remains unchanged and that they are still on board for the project. No official changes have been announced by the production team.
Platform Disagreement
Another internal issue reportedly involves a dispute over the global streaming platform. IU and Byeon Woo Seok are said to prefer the drama to be released on Netflix, due to its established global reach and simultaneous release model. Meanwhile, the production company and MBC are allegedly leaning toward Disney+, which has aggressively expanded its K-drama slate but has been criticized for delayed and inconsistent international rollouts. As of now, the official streaming partner remains unconfirmed.
Despite the swirling rumors and production hiccups, Wife of a 21st Century Prince remains one of the most anticipated Korean dramas in development. The combination of a high-profile cast, an alternate-history love story, and the reunion of two beloved performers has created strong buzz across fan communities. With both IU and Byeon Woo Seok still reportedly attached, viewers are eagerly waiting for filming to begin and for official updates to put the speculation to rest.
