After years of doing nothing in the palace, Isali, the little princess of the Divine Realm, has finally been given her first "mission" as a princess: a diplomatic visit to the Demon Realm. Yet this seemingly official assignment is met with firm opposition from her quiet, timid mother and her doting elder brother. It seems there are reasons they cannot bring themselves to speak of. But the God King, Isali's father, stands by his decision despite their objections, and sends Isali off to the Demon Realm in grand style.
The Demon Realm's high-ranking officials naturally give the princess of the Divine Realm a lavish welcome. The Demon Realm's eldest prince, Xi Se, becomes Isali's "tour guide," accompanying her for meals, play, and sightseeing. Aside from the occasional bickering, he proves attentive and considerate. One day, the two happen upon a secluded lake in the woods. To their surprise, the spell sealed within the lake draws them into another setting: a chapter in the Demon Realm's history from ten thousand years ago, when it was destroyed, a period never mentioned in the history books. The one behind it all seems to have mysterious ties to both the Demon Realm and the Divine Realm. Thus begins a difficult and winding journey to uncover the truth of the past. But what impact will this choice have on the future, and what will happen between the princess and the prince? Only time will tell...
