For those who are binge-watching or just starting, we've prepared a must-read summary of the characters and universe.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2026 South Korea: The Secret of the Constitutional Monarchy<\/h2>\n\n\n\n<p>The biggest charm of this show starts with the provocative premise: \"What if a royal family still existed in South Korea in 2026?\"<\/p>\n\n\n\n<p>However, it\u2019s far from a fairy-tale royal life. The royal family in the drama appears elegant on the outside, but in reality, they are on the 'brink of bankruptcy' due to massive maintenance costs and internal corruption. To reform the rotting monarchy and overcome the financial crisis, the royal family opts for a strategic 'arranged marriage' with a massive chaebol group that controls the nation's economy.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Core Character Analysis: Grand Prince Ian VS Sung Hee-ju<\/strong><\/h2>\n\n\n\n<p>\ud83d\udc51 Grand Prince Ian (Actor Byeon Woo-seok)<\/p>\n\n\n\n<p><strong>\ud83d\udc51 Grand Prince Ian (Actor Byeon Woo-seok)<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\" translation-block\">Traits: On the surface, a troublemaking playboy of the royal family who parties every day.<\/li>\n\n\n\n<li class=\" translation-block\">Hidden Truth: He is actually hiding sharp fangs.
