Duke’s daughter Luzeria fell in love with King Edward, married him, and became queen.
However, theirs was a white marriage—a marriage in name only. The king brought his baroness childhood friend Airi to the castle and became completely absorbed in her.

Worn out from her unrequited love for the king, Luzeria drinks a “love-erasing medicine” given to her by Akhil, a foreign apothecary, and lets go of her feelings.

Freed from her suffering and returning to her original cheerful self, Luzeria begins helping Akhil out of gratitude.
But when the king sees this, he suddenly starts approaching Luzeria again…!?
