Nia wakes up in a time-traveled body, dropped into a troubled noble family and adopted by Prince Zion. She arrives with a system that lets her see threats before they land, and the Crown Prince has already marked her new family for death.
Using the system's warnings, Nia starts blocking the Crown Prince's plans one by one, turning assassination attempts back on his own people. The more she saves her family, the more attention she draws — and the more the imperial court wants to know who this adopted girl really is. By the end, she is the most favored princess in the city, and everyone who tried to kill her family is afraid to say her name.
