Among the most talked-about upcoming Korean dramas, 21st Century Grand Prince’s Wife has quickly risen to the top of industry watchlists. Scheduled to air on MBC in April 2026, the series is set in a modern constitutional monarchy version of South Korea a premise that has inevitably drawn comparisons to the iconic 2006 drama Princess Hours.

The story follows Seong Hee Joo (IU), a chaebol heiress who has everything except noble status, and Prince Ian (Byun Woo Seok), a royal who possesses a title but no real power or wealth. Their romance unfolds as both characters attempt to break free from rigid class systems and inherited destinies.
