An arrogant and selfish earl's daughter named Elena Boulder loses her memory in a freak accident shortly after her engagement to Viscount Oscar West is broken off. The story unfolds during the final ten days before their engagement is formally and irrevocably dissolved.

The premise centers on a dramatic role reversal. Before the accident, Elena was known for having no positive qualities and being a difficult, infamous figure in noble society. Oscar, having already decided to end their engagement, viewed her with contempt. However, the amnesiac Elena behaves like a completely different person, displaying a personality that Oscar finds himself drawn to. As she accepts their impending separation with grace, he becomes conflicted and begins to wish he would not have to let her go.

The narrative tension stems from the fixed ten-day timeline. Elena is moving forward with her acceptance of the broken engagement, while Oscar struggles with his growing feelings and the consequences of his initial decision. The setting is a fantasy noble society where engagements carry significant social and political weight. Major narrative arcs track Elena's journey of self-discovery as she learns about the person she used to be, Oscars internal conflict between his past judgment and present emotions, and the countdown to the moment that will change both of their futures. Themes of identity, personal growth, and the impact of ones past on present relationships drive the story forward without the typical fantasy adventure elements.
