Nova, a brilliant but underestimated operative, is publicly humiliated by her fiancé and stepsister. Forced into a fake engagement with CEO Roman Knight by his grandfather, General Knight, for cover and project funding, Nova consistently surprises everyone with her hidden talents. She's a scientific genius (Dr. Vance) and a formidable martial artist, secretly working on a critical fusion project. Roman initially dismisses her as a "charity case" but grows increasingly suspicious and impressed by her intellect and skills, from Go mastery to drone repair and defeating trained bodyguards. At the Aegis launch, Nova, disguised as Dr. Vance, secures the contract for Knight Industries, fulfilling her end of the bargain for an annulment. However, Roman's formidable mother, Eleanor, a martial arts master and Nova's senior sister under the same mentor, unexpectedly embraces Nova after a physical "trial." Nova, now accepted into the Knight family, moves into the manor, leaving her old life behind.
