Rosa remembers her past life. She remembers reading about the Helios Empire in a novel before dying suddenly in an accident. Reborn as Rosa Veronica, she works hard to make ends meet until someone from the Duke of Estella's estate comes to fetch her. Meeting her biological father turns her life upside down as she's forced to live the life of Rozenta Estella, the sole heir and only son of the Duke of Estella. She decides to embrace this new life as the narrative unfolds. Despite knowing the story, she's surprised the male and female leads have not become the characters she's read about. Rosa learns to navigate Rozenta's life while fostering a budding friendship with Theodore and Vivian, though happiness doesn't last as all three grow up and enter the roles they've been born into.
