Violet Lawrence had a wonderful childhood as the princess of Lakraund. However, the royal family's business collapsed, the king passed away, and the remaining members fell into debt. Winter Blooming, the illegitimate son of a duke, repaid the Lawrences' debt in return for Violet's hand in marriage to better his social standing and gain a noble title. Everything begins to fall apart on Winter and Violet's wedding day. Violet's brother, Ash, suddenly announces that the royal family will renounce their nobility, rendering Violet completely useless to Winter. For three years, Violet lives quietly as a mouse, tortured by guilt and desperate for Winter's attention and love. Yet, not a single person looks her way—especially not her cold, avaricious husband. Seeking an escape from the misery and ridicule with no more attachment to her own life, Violet overdoses on pills. But instead of dying, she wakes up as Winter! Oblivious as to why they swapped bodies, Violet and Winter are forced to cooperate, slowly learning about each other's pains and what it means to be husband and wife. [Written by MAL Rewrite]
