The drama follows Seong Hee-ju, played by IU, a brilliant chaebol heiress who hides her pain behind elegance and power. Despite her wealth, she faces prejudice due to her commoner background. Her life changes when she crosses paths with Prince Lee An, portrayed by Byeon Woo-seok, a royal who has the bloodline but no real authority or wealth. What starts as a calculated arrangement soon turns into an emotional journey that defies class and destiny, showing how love can bloom even under the weight of societal barriers.
Supporting the leads are Noh Sang-hyun and Gong Seung-yeon, adding depth to the royal and corporate drama surrounding the main couple. The chemistry between IU and Byeon Woo-seok is already being praised by fans, especially after the teaser release showing their first powerful encounter. The storyline promises both emotional intensity and grandeur — a modern fairy tale set in a 21st-century monarchy.
Produced by MBC and Kakao Entertainment, this drama aims to mix modern romance with historical prestige. The lavish visuals, intricate costumes, and emotional storytelling make it one of the most anticipated series of 2026. With IU’s charisma and Byeon Woo-seok’s rising popularity, 21st Century Grand Prince’s Wife could easily become a standout in K-drama history.
