What would happen if someone from the future had the opportunity to be reborn into the past with a different appearance and life twist curtains? Erica is a girl who is living a miserable life, and then one day, an angel comes to see her. The meeting ended where Erica was reborn as another girl named Este, the illegitimate child of a noble because her mother was just an ordinary concubine. Having lived in her father's magnificent residence, she was expelled as a peasant with her mother by her father's legal wife when she was a child. Deciding to accept her destiny, Este is determined to change the course of her future by becoming a maid at the residence of a prince she is avoiding. This new independent life confronts Este with much pressure, but because she has a firm stand, she attracts the attention of nobles, one of whom is Prince Carl Zeiss. The figure of a core noble known to be cold and has a hot love life that has become an open secret. When she is about to be condemned to death, Este gets help from Prince Carl Zeiss. Instead of taking refuge with Prince Carl Zeiss, that fell for her, Este disappeared, making it seem like someone had obliterated her. Then thanks to a unique offer from a duke, Este was reincarnated in front of everyone as the principal noble's daughter. Unfortunately, her new appearance creates a great stir, so she unknowingly meets new enemies who want her death again. At the same time, Prince Carl Zeiss tried to sniff out the traces left by Este. It formed two great fortresses, and war between the nobles seemed inevitable. Everything is based on the struggle for the throne and love its own.
