It’s 1258. A kingdom has fought Mongolia for 30 years and is close to collapse. A sacred relic could change everything, and a closed-off princess might be the one to help. Sacred Jewel just released its first look at Claudia Kim’s character, and it’s already setting a haunting tone.

The Story

Goryeo is on the brink of defeat after three decades of war with Mongolia. An expedition unit marches into battle in search of the Avalokitesvara Bead, a sacred relic believed to hold divine power to protect the nation. Meanwhile, a princess works to save them. For context on the real history, see the Mongol invasions of Korea on Wikipedia.

Meet the Princess: Wang Hee (Claudia Kim)

Wang Hee is the emperor’s youngest daughter. The pain of a political marriage and personal loss has closed her heart to the world.

She’s cold and indifferent to others’ opinions.
She spends her days in boredom at Gyeonghwa Palace.
Her life changes when she meets a young military commander.

Meet the Commander: Baek Gyeol (Ahn Bo Hyun)

Baek Gyeol is full of passion and innocence, which is the opposite of the princess’s guarded calm. The two fall in love, and their romance takes place against a war that could end the kingdom.

Why It Could Be Special

Few dramas combine epic war stakes with a quiet emotional arc. Here, the heroine’s slow thaw matters as much as the quest for the relic. Pairing Claudia Kim’s reserved royal with Ahn Bo Hyun’s passionate soldier suggests a contrast that works well on screen.
