Out of fear, Arshe kills her brother who would have become the king, and gets imprisoned inside the palace. Later, a prince comes from the Empire and gives her a secret offer.

Arshe, who has always wished to live a stable life, is told by her brother that there was a marriage proposal from a neighboring country. When she’s forced to be sent there, she gets frustrated, worrying that she might get killed in a foreign land. After poisoning her brother to death, Arshe is locked up inside the palace. Then one day, a prince comes from the Empire to visit her.

During a chance meeting, Princess Asché shares an unforgettable kiss with Ethan, the second prince of a nearby empire. Years later, Asché’s brother arranges a marriage that will force her to become the Emperor’s ninth wife. Rather than suffer in a loveless union, Asché poisons her brother, and is imprisoned in the palace for her crime. But as revolution stirs, Ethan, now an anti-imperial rebel, suddenly reappears in her bedroom, and a steamy romance fraught with political implications begins.
