Born with an incomplete soul and mentally impaired, Millie Harper was tricked by her parents into taking the blame for her sister's crime and was imprisoned for five years. In prison, she mastered deadly combat skills under the guidance of a ruthless mentor. On the day of her release,just as her ashamed parents try to commit her to an asylum, Isaac Bowen, heir to the nation's most powerful family, appears and marries her on the spot.

On their fifth anniversary, Emily discovers that she has merely been a “stand-in” for her boyfriend’s first love, Evelyn. Emily immediately breaks up with Ethan and returns to her old life as an up-and-coming researcher. Having long concealed her status as a brilliant scientist, she earns the support of Daniel, the youngest professor at a prestigious university, and ranks first in gaining admission to the PhD program under her dream advisor. Through hard work and resilience, Emily proves her worth to others and simultaneously exposes the carefully constructed persona that Evelyn built for herself. Only then does David realize exactly what Emily is truly capable of, as well as the love she poured into their relationship, leaving him filled with nothing but deep regret as he watches her flourish in her newly reclaimed life.
