JTBC has pulled back the curtain on its big-budget historical drama Sacred Jewel, giving viewers a first look at the main characters. The show is set in 1258 during the Goryeo Dynasty, a time when the kingdom is about to fall after 30 years of war with Mongolia. The story follows a small team of fighters who go on a very dangerous mission to find a holy relic that could save their country.
The drama comes from director Jung Dae Yoon, who made popular shows like Reborn Rich, W, and She Was Pretty. The script is written by Jung Hyun Min, known for The Nokdu Flower and Assembly. This team has a strong track record, so people are paying close attention to this project.
The Main Cast and Their Characters in Sacred Jewel
Ahn Bo Hyun plays Baek Gyeol, the special commander of the expedition team. His job is to find the “Avalokitesvara Bead,” a holy jewel that people believe has divine power to protect the nation. The show calls this relic the Goryeo-era “Holy Grail.” Baek Gyeol used to be a member of the royal guard. He gets sent on this deadly mission after he falls in love with the emperor’s daughter. The first character stills show him looking sad but calm, hinting that he is a man with hidden passion and a bit of innocence underneath his tough outside.
Lee Sung Min takes on the role of Choi Gu, the leader of an elite Goryeo military unit called “Yabyeolcho.” He is a seasoned veteran who has survived countless battles. His face shows the scars of war and the heavy weight of past events. Choi Gu is put in charge of leading the expedition alongside Baek Gyeol, who has much less experience. Lee Sung Min’s strong acting is expected to bring a lot of depth to this hardened character.
Claudia Kim stars as Princess Wang Hee, the youngest daughter of the emperor. Her character still shows a bold and commanding presence. Princess Wang Hee has closed off her heart after going through a political marriage and personal loss. She lives a quiet life in Gyeonghwa Palace. That changes when she meets Baek Gyeol, which stirs up emotions she has kept hidden for a long time. Her cold and unreadable gaze shows an inner strength that does not shake, even when people watch her every move.
Ha Yun Kyung transforms into Geol Seung, the owner of a tavern on Ganghwa Island. She also works as a guide for the team. Baek Gyeol asks her to join the mission. She brings a free-spirited charm and unpredictable energy to the journey. Her bright and playful expression in the stills highlights her lively personality. Her resilience adds a sense of life and vitality to the otherwise dark and serious story.
Yoon Kyun Sang plays Wang Mu, the defense commander of Wonju Fortress. He is also Princess Wang Hee’s first love. He appears in armor on a horse, showing a quiet but firm presence. Wang Mu is a distant royal relative who has been pushed aside by political forces. He has spent his life on the edges of power. He carries the pain of having let Princess Wang Hee go once. Now, he finds himself pulled back into the center of big events.
Sacred Jewel Gets Invitation to Cannes International Festival
Before the show even airs, Sacred Jewel has already made a mark on the global stage. The production company SLL announced on April 1, 2026 that the drama has been officially invited to the 9th Cannes International Series Festival (Canneseries). The festival takes place from April 23 to April 28 in Cannes, France.
The show was selected for the “Rendezvous” section, which is a non-competitive category. In this section, directors and actors take part in screenings and walk the pink carpet. Ahn Bo Hyun and Claudia Kim will attend the festival on behalf of the series. They are set to meet global fans through these events, marking the drama’s official step into the international market. This invitation shows that people are already taking notice of the show’s high quality before its domestic release.
Background on the Story and Production
The drama uses the real historical setting of the Goryeo Dynasty in 1258. At that time, the kingdom was facing near destruction after three decades of war with the Mongol Empire. The “Avalokitesvara Bead” that the team searches for is a fictional relic, but it represents the hope and desperate measures people might take when their nation is collapsing.
The director Jung Dae Yoon is known for mixing strong visual storytelling with tight narratives. His work on Reborn Rich was a massive hit. The writer Jung Hyun Min has experience with historical political dramas, which suggests the show will have smart dialogue and complex characters. The first set of character stills released on April 14, 2026, focuses on the five main figures, each shown with their own beliefs and pasts that will clash and connect during the journey.
