Goong, and The Palace Princess Hours is based on the same titled manhwa by Park So Hee. Goong is a story about young love in the face of tradition, politics, and intrigue. In an imaginary world, modern-day Korea is a constitutional monarchy and the Royal Family lives in a grand Palace, the Goong. The story opens with the sudden death of the reigning King. Faced with the decreasing popularity among the public for the Royals, a grand wedding for the Crown Prince, Lee Shin (Joo Ji Hoon), is decided to be the best publicity move to improve the image of the Royalty and at the same time prepare Shin for immediate succession. The intended bride? The headstrong, awkward, and sweet-spirited Shin Chae-kyung (Yoon Eun Hye) that just happens to go to the same exclusive art school. Chae-kyung was betrothed to become the next Crown Princess by her grandfather and Shin's grandfather. After 14 years of living in England with his mother, Lee Yul (Kim Jeong Hoon) appears out of nowhere. He is Shin's cousin, as well as the former Crown Prince. Everything seems to be going normally, until Chae-kyung's optimistic spirit wins the heart of the internally lonely Yul. As the Crown Prince Shin and simple-minded Chae-kyung's relationship appears to be developing deeper feelings, a series of scandals are exposed to the public right after the pair were officially announced married. Will love prevail in a world of political pressures and marital hardships? Or will being in the spotlight be too much for the young newlyweds to endure?
