When the strong-willed Im Jeongah reads a novel titled The Flower From Another World, she sincerely relates to the villainess. Empress Robellia Blanchett is slowly pushed out by the saintess from another world, Aisha, who wins the heart of the tyrant emperor, Alexandros Grandia Kshayarsha Le Castilla. Robellia eventually dies, and Alexandros never even bats an eye.

Jeongah suddenly awakens in Robellia's body, determined to break free and repeatedly demand a divorce until the emperor yields. The new Robellia has no emotional connection to her indifferent husband, though she quite dislikes Aisha's obvious pretense. Although Alexandros harbors no kind feelings for Robellia, her uncharacteristic request and subsequent acting out only pique his curiosity. The more outrageously Robellia rebels against him, the more Alexandros holds onto her, unwillingly falling for both her haughty temper and tender heart.
