Cunning and ruthless, Lady Medea Solon has only had one goal in her life: to become the princess of the Vasilios Empire by marrying Crown Prince Eros Orna Vasilios. However, Medea's ambitious scheme collapses when the crown prince chooses naive Psyche Callista as his fiancée instead of her. As a result, she resolves to remove Psyche by any means necessary and secure her place on the throne.

However, not all goes according to her plan. At the Yearly Prayer held in the Temple, Medea confronts Psyche and her ignorance toward possessing unfathomable authority. In an instant, Medea falls into a seemingly bottomless fountain, unable to reach the surface. Believing that God is responsible, she prays to be the one who rules the empire.

The deity grants Medea's wish at the cost of exchanging bodies with Psyche, a twist of fate that may reveal more than what meets the eye.
