The narrator has a talent for understanding social dynamics and has chosen to act as the antagonist to ensure her sister Marin is seen as the suffering heroine, as Marin otherwise risks losing her food rations from their father. At a social gathering, the young heir of the Balgoa Marquisate, Rio, is present. She plans to help Marin by splashing wine on her dress, intending to create a scandal. However, instead of the expected outcome, Rio seizes her wrist and breaks it, marking the beginning of an unexpected encounter.
