The MBC drama '21세기 대군부인', starring IU and Byeon Woo-seok, has faced intense backlash over historical inaccuracies and perceived distortions. Critics, including Sungshin Women's University professor Seo Kyoung-duk, argued that the series provided ammunition for China’s Northeast Project by depicting elements like '천세' (thousand years) and incorrect royal attire. Following public outcry, director Park Joon-hwa, the lead actors, and finally screenwriter Lee Ji-won issued formal apologies on the official website on March 19, acknowledging failures in historical research and documentation. | The MBC drama '21세기 대군부인', starring IU and Byeon Woo-seok, has faced intense backlash over historical inaccuracies and perceived distortions.
