(The entire story is set in a fictional world.)
After traveling back to 1980, Yang Yuwei finds herself in a tiny three-square-meter bedroom with no windows or lock. The original owner is the family's live-in maid, invisible to everyone around her.
To outsiders, the original owner is strange and antisocial, lazy and greedy. Her father is successful in his career; her stepmother works tirelessly and is the model of a virtuous wife and loving mother; her stepsister is gentle and charming, and her younger brother is lively and adorable.
Apart from the original owner, the odd one out, the rest of her family has an excellent reputation throughout the residential compound.
Everyone in the compound has forgotten that her stepmother's job and the house they live in both belonged to the original owner's birth mother. Her father remarried his first love less than six months after her mother died. Her stepmother entered the family with a daughter a year older than the original owner, then gave birth to a son just seven months later.
Worse still, the original owner is about to graduate from high school and inherit the job her birth mother left behind.
To avoid giving the job back to the original owner, her stepmother is discussing marrying her off. She plans to get as much as she can out of the arrangement, using the original owner's marriage to secure a job for her own nephew.
The original owner has become timid and helpless in this environment. Her only act of defiance is wanting to apply to medical school. She plans to force her birth father to give in by refusing to eat, but in the face of someone who doesn't love her, this proves useless. In the end, she loses her life instead.
Yang Yuwei, a genius doctor from the twenty-first century skilled in ancient martial arts, becomes a pitiful girl in 1980. See how Yang Yuwei takes on her scumbag father and poisonous stepmother, builds her medical career, and rises to the top.
