In a world where the “VIP of the Underworld” is known for meeting an untimely demise, the young Sangra Heeyo, the beloved daughter of the Jade Emperor and the King of the Underworld, finds herself in a precarious situation. Despite her divine lineage, she suffers from a frail body.
When she learns of the heart-wrenching tale of Seruha, a mortal princess in the Underworld who has lost her will to live, Heeyo resolves to take action. Defying celestial rules, she sneaks away to the human realm to assume Seruha’s identity, leaving her parents in the dark.
However, upon waking in the Empire of Un, she discovers that she has been treated like a pawn in a political game. The empire is rife with threats, not only against her but also against her new husband, Crown Prince Cheon Gyeol-woo, who is himself a target of deadly assassins.
Determined to protect the innocent and thwart the villains that plague her new life, Heeyo realizes that she can’t simply stand by while chaos unfolds around her.
