Utsukushii Sub Chara Koushaku no Tsumori ga Onna Deshita

Before dying suddenly in an accident, Rosa read a novel set in the Helios Empire. Reborn into that exact world as Rosa Veronica, she spends her early years working tirelessly to survive. Her modest life is upended when emissaries from the Duke of Estella’s estate arrive to retrieve her. Upon meeting her biological father, she is thrust into an entirely new existence as Rozenta Estella, the duke’s sole heir. With the aid of magical artifacts, Rosa successfully assumes the identity of this minor male supporting character from the story she once knew, choosing to embrace the unfolding narrative. Yet the familiar plot quickly deviates from her expectations. The male and female leads are nothing like the characters she remembers reading about. Despite these surprises, Rosa adapts to the complexities of her new family and role, forming a genuine bond with Theodore and Vivian. However, their shared happiness proves fleeting. As the three grow older, they are inevitably drawn into the demanding roles they were born to fulfill, forcing Rosa to confront the unpredictable reality of a story she thought she already knew.
